Lunar Sample Atlas

This library of images provides pictures of the Apollo samples taken in the Lunar Sample Laboratory, full-color views of the samples in microscopic thin-sections, cutting views and diagrams that illustrate how the samples were subdivided for scientific analyses, and in situ views of the samples on the lunar surface. The atlas contains information about the type of sample (e.g., rock, soil), the lithology (e.g., basalt, norite), and a description of the sample. Links to additional information about each sample are provided for those that have been previously described in The Lunar Sample Compendium and Lunar Sample Catalogs. Version 1 of the atlas was released in August 2009 and version 2 was released in July 2010. The process of scanning lunar sample images continues and the atlas will grow in the future.

A subset of this collection, the Apollo Thin Sections catalog, includes all samples for which thin-section views are available. Another subset, the Virtual Microscope catalog, provides interactive views of selected thin sections as they would be seen through a microscope. Another rich source of thin-section views by William Phinney (formerly with the NASA Johnson Space Center) and Howard Wilshire (formerly with the U.S. Geological Survey) is the Digital Petrographic Slide Collection, which is hosted by our colleagues at Arizona State University.

Sample Number Sample Type Lithology Description
12001 soil-general   12001 is <1 cm fraction of bulk regolith collected about 30 meters northwest of the LM on the first EVA traverse. Astronaut Conrad saw several beads of pure glass while collecting this sample. Fryxell reports that the fines are weakly coherent; they adhere to rocks and do not slump when the sample holder is tipped 45 degrees.
12002 rock basalt  
12003 soil >1 cm   12003 is coarse (>1cm) split from 12001, along with friable material from the bottom of the sample box. This was collected about 30 meters northwest of LM on EVA-1. These broken up fines from larger rocks do not make a statistical sample.

The sample was collected on a gentle southward slope and was partly buried. The area was characterized by abundant fragments ranging from the limit of resolution up to 1.5 m blocks. The sample was returned in documented bag 7N in ALSRC 1006.
14052      
14053 rock basalt holocrystalline, fine-grained, equigranular mare basalt (Carlson and Walton 1978); basalt (Wilshire and Jackson 1972) and (Quaide and Wrigley 1972); and mare basalt (Simonds et al 1977)

14059   breccia Sample 14059 was collected during the second EVA from station E. It was placed in bag 15N by the astronauts, and returned in ALSRC 1006 along with samples 14055-14062. Sample consists of two pieces, larger being irregular in shap and smaller being subrounded.
14060 rock breccia Sample 14060 was collected from station E during the second EVA. It was placed in bag 15N by the astronauts and returned in ALSRC 1006 along with 14055-14062. Sample is well rounded (almost spherical), friable, fragmental rock and is medium gray in color.
14061   breccia Sample 14061 was collected druing the second EVA from station E. It was placed in bag 15N by the astronauts and returned in ALSRC 1006 along with 14055-14062. (Sample 14062 is residue). Sample is friable and appears grayish brown in color. It is an equidimensional, subrounded block.
14063 rock breccia So-Called "White Rocks"; friable with dark clasts (Wilshire and Jackson 1972); annealed or slightly annealed, feldspathic Fra Mauro breccia (Chao et al 1972); "white rock breccia" (Quaide and Wrigley 1972);
14064 rock breccia Sample 14064 was collected in the White Rocks area at Station C1 and was returned in bag 16 along with 14063 and 14065 (residue) in ALSRC 1006. There was a strong feeling at the LRL that 14064 and 14063 are parts of the same rock because not only do they look very much alike, but 14064 has a protruding 1 cm clast, while 14063 has a 1 cm clast mold. Shepard stated that he had put "a couple" of hand specimens into bag 16, which is what was found. Sample 14064 is one of those studied by the Imbrium Consortium. Sample is pale gray with leucocratic matrix and contains approximately 40% clasts and 60% matrix. The sample is friable "white rock".
14066 rock breccia Sample 14066 was collected at Station F on the second EVA. The sample was found in the vicinity of Weird Crater. Sample was returned in documented bay 17N in ALSRC 1006.

14067      
14068 rock breccia Sample 14068 was collected during the second EVA from station C1 and placed in bag number 10. It is one of the surface rocks collected while a gray layer, just under the surface, was samples 14140-14143; blocky, gray, coherent, holocrystalline, melt rock with less than 5% clasts.
14069 rock breccia Sample 14069 was collected at Station C1, 1.28 km ENE of the LM and 100 m SE of the rim of Cone Crater during the second EVA. The material at C1 appears to be material originally ejected from Cone Crater and re-ejected from a 30 m crater just south of Station C1 (Swann et al., 1977). Sample is block, gray, finely crystalline breccia with a sugary texture.
14070 rock breccia Sample 14070 was collected from Station C1, 1.28 km ENE of the LM, and 100 m SE of the rim of Cone Crater during the second EVA. It appears to have been ejected from Cone Crater that was later re-ejected from a 30 m crater in the vicinity (Swann et. al., 1977). This is a blocky, subangular, coherent, light gray, crystalline breccia that is similar to 14069.
14071   breccia Sample 14071 was collected at Station C1 approximately 1.28 km ENE of LM and 100 m SE of Cone Crater. The area is locally flat with a slight southerly slope. The sample was collected amongst abundant debris ranging in size from the limit of resoution up to 75 cm. The photo-documented area was too disturbed to be able to see any intact craters. The sample was returned in documented bay 10N in ALSRC 1006. All the samples collected in the vicinity of 14071 are blocky and angular to subrounded with very rough surfaces.
14072 rock basalt Sample 14072 was collected at Station C1 approximately 1.28 km ENE of LM and 100 m SE of Cone Crater. The area is locally flat but generally slopes slightly to the south. The area is strewn with debris which ranges in size from the limit of resoution up to 75 cm. The debris is mainly angular to subrounded. The entire area of photo documentation is too disturbed to see any intact craters. The sample was returned in documented bag 10N in ALSRC 1006. Sample is medium light gray basalt and is somewhat smooth in appearance. The shape is blocky to subrounded and the rock is extremely coherent.

They share a common lithology which is especially evident along the broken surfaces. These samples were returned together in weigh bag 1027 which also contained samples 14305/302 and various smaller chips (see Phinney et al., 1975). These samples were examined in the CRA and NNPL by the PET< and 14303 was extensively distributed for scientific experimentation. Sample 14304 has been designated a posterity sample. This rock (14303) is a coherent, gray, block to subrounded breccia.
14304 rock breccia These samples (14303 and 14304) are pieces of a football-size rock collected from a location 80 m NNW of the LM during EVA 1.

This coherent, gray breccia has a rounded surface and an angular flat underside.
14316 rock breccia Sample 14316 is a breccia collected at Station H during EVA 2. It has not been identified in lunar surface photographs, so its exact lunar location and orientation are unknown. It was returned in weigh bag 1038. This rock is a medium gray, inhomogeneous, fragmental breccia with one flat face. There is a predominance of leucocratic clasts.
14317 rock breccia Breccia sample 14317 was collected at Station H during the second EVA but has not been identified in the North Boulder Field photographs, so its lunar location is tentative, and lunar orientation, unknown. It was returned in weigh bag 1038. This rock is a medium gray, coherent breccia.
14318 rock breccia Breccia sample 14318 was collected from the regolith near the south end of North Boulder Field at Station H during the second EVA. It was returned in weigh bag 1038. Sample 14318 is one of the specimens chosen for study by the Imbrium Consortium, who received 14318,0. A complete set of matched thin sections, across the entire specimen was made by the Consortium (1976); This sample is a very coherent, gray, polymict breccia consisting of light gray clasts in a medium gray matrix.

This sample as well as 14312 were collected from Turtle Rock at Station H during the second EVA and returned in weigh bag 1038. Its lunar orientation and location have been well documented. It appears to be similar to Turtle Rock and the other rocks in the area. This is alight-medium gray coherent breccia which is flat on one side and rounded on the other side.
14320   breccia This breccia was collected from North Boulder Field from Station h during EVA 2. The sample has not been identified in lunar surface photographs so the lunar location is only tentative and the lunar orientation is unknown. Sample 14320 was returned in weight bag 1038. This is a medium gray, coherent, polymict breccia.
14321 rock breccia largest sample returned during Apollo 14 mission; also known as "Big Bertha". This sample is the third largest sample returned by any Apollo mission. This breccia was collected during the second EVA at Station C1, near the rim of Cone Crater. A voice transcript made during the collection, as well as a more detailed discussion of the lunar environment can be found in Geological Survey Professional Paper 880 (Swann et al., 1977). The sample was returned in bag 1038. This large sample is typical of the apparently dominent rock type in the Cone Crater ejecta blanket. It is a moderately well-indurated breccia, in which predominately dark clasts are set in a lighter matrix. The relative abundance of this rock type suggests that it is probalby representative of the Fra Mauro Formation. This rock, 14321, is a partly annealed, moderately coherent polymict breccia. The blocky surface is gray with patches of black and white.

15016   basalt Lunar Sample 15016 is a highly vesicular, olivine-normative, basalt with a major element composition similar to that of non-vesicular basalt 15555. It is a medium-grained basalt with subhedral phenocrysts of zoned pyroxene (1-2 mm) and olivine (~1 mm) set in a matrix of subophitic intergrowths of pyroxene and plagioclase.
15017     Ryder (1985) gives a description of 15017. It is a very vesicular glass with numerous included mineral grains. Only the outside surface was smooth and shiny. Some interior vesicles were open to the outside. There were a few zap pit on some of the surface, but little accretionary material.

15030 soil-general   At Station 8, Astronaut Irwin dug the deep trench; samples 15030 through 15034 were taken from the bottom of the trench. The trench area is similar to the area near the ALSEP, a smooth, hummocky surface of fine grained material with rare, cobble sized fragments not visibly related to any particular crater. The trench wall was described by the astronauts as uniform, with perhaps a slight color darkening in the middle part, above a hard layer which was not penetrated, but just reached at a depth of about 35 cm.

The trench wall was described by the astronauts as uniform, with perhaps a slight color darkening in the middle part, above a hard layer which was not penetrated, but just reached at a depth of about 35 cm. One small fresh crater occurs a few meters north of the trench, but it is too distant to add a significant layer of ejecta to the top of the trench area.

15059   regolith breccia Ryder (1985) described 15059 as a "tough regolith breccia containing mare basalt and KREEP basalt and abundant glass, in a glassy matrix. A thin very vesicular glass coat covers most of the sample and intrudes it along fractures."
15065   basalt 15065 is a coarse-grained mare basalt that is about 3.35 b.y. old.
15070   soil Soil 15070, rock sample 15075, and rock sample 15076 were taken from a small area about 25 m east of the rim of Elbow crater at Station 1. The samples were taken as the middle part of a three part radial sample of the ejecta blanket of Elbow crater. The soil and two rock samples were placed in the same sample bag.

15075   basalt 15075 was one of several basalt samples collected as a radial sample near the rim of Elbow Crater (15065 through 15085). They all appear to be similar (Ryder 1985) . 15077 is interpreted as a "sister" sample to 15076.
15076   basalt 15076 is a coarse-grained, porphyritic pigeonite basalt with subophitic matrix. It has been dated at 3.35 b.y. and has been exposed on the lunar surface for ~300 m.y. (Elbow Crater ?). The top surface is rounded with numerous micrometeorite craters.

15085   basalt It is one of the samples collected as a suite, from different distances from a small crater (15065 to 15085). It is a is about 3.4 b.y. old and is coarse-grained, quartz-normative mare basalt (catalog reports 5 mm) dominated by pigeonite.
15086   regolith breccia Soil 15080 and two cobble-sized rocks, 15085 and 15086, were collected at Station 1 about 65 m east of the Elbow crater ejecta rim. This collection was the farthest from the rim of the three part radial sample of ejecta blanket. In the local area of this sample, the general ejecta blanket appears smooth with scattered cobble sized rocks. A chip from friable breccia 15086 was put through freeze-thaw cycling and ultrasonic vibration to disaggregate, then sieved.

15088      
15090   soil Samples 15090 through 15093 and 15095 were collected near a large boulder at Station 2. The regolith is notable for its fine texture. Coherent fragments larger than a centimeter in diameter are scattered, and none larger than 10 cm in diameter occur within the immediate sample locality. The soil can be assumed representative of the mature, well gardened regolith composed of St. George crater ejecta plus whatever exotic components have been admixed since the St. George impact.

15100 rake soil Sample was collected at the rake sample site 5m east of the large rock at Station 2. The mature fine grained regolith with a few scattered fragments up to about 10 cm in diameter is characteristic of the entire Station 2 area and presumably represents intensely gardened St. George ejecta to which some ejecta from impacts elsewhere in the Apennine Mountains and Imbrium basin have been added. This sample has not been studied.

15105   basalt According to Swann et al. (1972), lunar basalt 15105 as a small rock (peanut) collected with soil from station 2 at Apollo 15. It is a fine-grained, olivine-normative mare basalt with relic olivine phenocrysts
15115 rake basalt 15115 is a relatively coarse basalt and was collected as a rake sample from station 2, Apollo 15..
15116 rake basalt 15116 was collected as part of a rake sample from station 2, Apollo 15 (Swann et al. 1972). It is a coarse grained pyroxene-rich mare basalt and has not been dated.
15117 rake basalt Collected by rake as part of a comprehensive sample taken at station 2, Apollo 15 (near St. George Crater and the Hadley Rille); a coarse-grained pigeonite basalt similar to 15115 and 15116. It has been dated at 3.35 ± 0.04 b.y.
15118 rake basalt Lunar sample 15118 was collected by rake as part of a comprehensive sample; chemically it is a quartz-normative basalt with pyroxene phenocrysts set in a fine groundmass. It has not been dated.
15119 rake basalt 15119 is an olivine-normative mare basalt with a microporphyritic texture. The phenocrysts are small, sparse, and yellow-green olivines. A regolith breccia adheres to the basalt, hence the basalt is actually a clast. The basalt is tough; the regolith breccia is friable and brownish-gray. Zap pits occur on the regolith breccia, and the basalt has a few vugs.
15124      
15125 rake basalt It is a pyroxene-phyric basalt, with numerous skeletal pyroxenes and some olivine embedded in a dark, cryptocrystalline matrix (quench texture). The composition and texture of 15125 are similar to that of larger sample 15597.

15200   soil Soil 15200 and fragments 15201 through 15206 were broken from the 1 m boulder at Station 2. The boulder appears to be an ejecta fragment from a relatively recent impact of another site. The boulder may have impacted at a low angle and rolled uphill onto the rim of its own secondary crater. Sample area is generally flat and free of fragments. Carrier notes that this is an unrepresenative collection of rock chips and loose soils found at the bootm of a sample bag.
15201   soil These soil were collected adjacent to the small boulder at station 2, Apollo 15. 15205 and 15206 were chipped off of the boulder and when 15205 was picked up, some soil (19201) was placed in same bag. !5211 was collected as a “fillet” sample of the boulder

15205   breccia 15205 is noteworthy in that it contains a high percentage of KREEP basalt fragments as clasts, but also contains fragments of the mafic green glass, and mare basalt found in the Apollo 15 regolith. 15205 has not been dated, but it has an exposure age of 169 m.y. It has a thin coating of vesicular glass on most surfaces, such that it must have broke free from the boulder along an interior glass vein. Micormeteorite carters on an exposed surface have been carefully studied.
15206   impact melt breccia It is a vesicular glassy breccia containing KREEP basalt and mare basalt clasts. Unlike 15205 the clasts are shocked and penetrated by glass and there is a higher proportion of matrix (figure 3). It is an impact melt rock, that was probably generated from a regolith.

15256 rock breccia 15256 is a rare type of lunar breccia, made up of mostly mare basalt fragments, that are welded together; is rounded, aphanitic, coherent and covered with micrometeorite craters on most sides. It is made up of fragments of olivine-normative basalt and lacks fragments of pyroxene basalt (the other main variety of Apollo 15 basalt). The sample lacks a signature of meteoritic siderophiles and was not a soil. This rock has not been dated.

Sample 15012 was also collected at the bottom of this trench and placed in a Special Environmental Sample Container. The surface where the trench was dug is littered with fragments ranging from .5 - 2 cm size, but distinctly fewer than on the north rim of the same crater.

They are breccia fragments from the same location as 15265. Consist of all components of the soils in a fragmental, perhaps partly glassy matrix and contains, besides ophitic and intersertal basalts, plagioclase breccias, troctolites, noritic fragments, glass and individual mineral grains.
15286   breccia It is a coherent glassmatrix soil breccia, similar to other samples collected at same time. Ryder (1985) even suggests that 15286 may be spalled from 15265-15267, but that seems impossible because glass wraps around the particle.

Soil 15290 includes soil from the immediate area and possible some fragments from 15295 which may have disintegrated in transit and handling into additional fines. This comminution of the breccia enriches the large size fractions of this soil and degrades the pristinity of the grain size distribution.

One side is shiny; the other dusty. The sample is broken slightly, revealing its hollowness, and at least where it is broken the walls are thin. It has never been processed or allocated. It was observed by the astronauts on the lunar surface and put in the container with soil".
15308   impact melt breccia It is a clast-rich impact melt rock with high content of trace elements. It has not been successfully dated.
15310      
15311 rake   Soil sample 15310 was collected as part of a large rake sample and may contain material rubbed off of the friable rocks collected by the rake. On the other hand, it is certain to also contain some soil collected by the rake and/or attached to the rocks. In any case 15311 is a large soil sample that goes along with 15301 and it has about the same composition.. The fines from this sample have not been characterized.

15382 rake basalt pristine feldspathic basalt with high rare-earth-element content. Only a few pristine samples of this important rock type were returned from the moon, also including 15386 and fragments in 15434 and other Apollo 15 soils. These fragments were recognized as samples of chilled volcanic liquid and have been a source of much speculation
15383      
15384      
15385 rake basalt These small samples are found to have high Mg content, probably due to olivine accumulation (another “picritic basalt” from Apollo 15 is found as a large clast in breccia sample 15459). The formation of 15385 has been dated at 3.4 b.y. with exposure to cosmic rays for about 280 m.y.
15386   basalt 15386 is the largest sample of pristine KREEP basalt in the collection. By pristine we mean that it is lacking in meteoritical siderophiles (Ir, Re, Au etc), and hence not contaminated by meteorite debris. Thus it is thought to represent an indogenous lunar volcanic melt derived from the lunar interior (see discussion in 15382).

15400   soil Soil 15400 and green breccia 15405 were collected from the singular rounded 3 meter long boulder and from an apparent fillet developed high on the south side of the boulder. Relatively few fragments occur in the vicinity of the rock. Most are angular and lie on the fillet, but sparse fragments are found with random distribution in all directions. The samples are probably representative of the boulder and its disintegration products which may typify the composition of its fillet.
15401   soil is very immature and it has an unusual grain size distribution weight towards large particles. The average grain size distribution of 15401 is 89 microns.

Prominent clasts include mineral fragments of plagioclase and pyroxene, along with lithic clasts of KREEP basalt, granite and quartz monzodiorite (QMD). Flow banding in the matrix includes small irregularly-shaped vugs.
15410   soil Collected at Station 7 from the summit of the subdued rim crest of Spur Crater. Local surface is moderately well populated with rock fragments up to tens of centimeters across. The sample area is characterized however by the abundance of less than 1 cm size fragments. Several large fragments in the sample have been excluded from the grain size analysis.

72320   soil 72320 was collected at Station 2, near the base of the South Massif. This "shadowed soil" collected about 20 cm under the east - west overhang of a 2 meter diameter boulder. The sample area is a strewn boulder field with boulders up to 2 meters across common. Craters up to 10 cm are abundant in the immediate sample area. The soil probably does not have as complex an exposure history as rake sample 72500 because of the protection from the rock overhang.

74220   soil Considered to be a clod of friable material taken 6-8 cm deep in a trench from Station 4, on the rim of 120 meter Shorty crater. The site is near the low place in the crater rim crest. The fragments population is highly variable, craters up to several meters in diameter are common. The particles larger than 1 mm are mostly friable clumps that disagregated during sieving. Any discontinuity is probably due to the fact that the sizes <1 mm were sieved and the sizes >1 mm were hand picked.

79001 core soil Double drive tube 79001/79002 was taken 2 meters from two 1 meter craters on the southeast flank of the Van Serg crater ejecta blanket, at Station 9. The site has a gentle slope to the southeast away from Van Serg crater. Fragments 2-20 cm cover 3% of the surface. Astronauts report that driving the first core was easy. The second one was a little tougher, and then it got very hard at the end. >1mm particles were hand picked and not sieved, where they would have broken down, so there is a discontinuity in the size distribution caused by the lab procesures.
