Sample No.: RKPA80202

Location: Reckling Peak

Field No.: 1036

Weight (gms): 544.5

Meteorite Type: L6 Chondrite

Physical Description: Carol Schwarz

Less than 1.5 mm thick, brown to black fusion crust covers the entire specimen except for one small area. The fusion crust is polygonally fractured. White evaporate deposit was visible in some of the fractures after the stone dried overnight in the nitrogen cabinet. Interior material is gray with some oxidation halos. A number of parallel fractures are present. Some weathering has occurred along these cracks. Dimensions: 12 x 5.5 x 5.5 cm.

Petrographic Description: Brian Mason

Chondrules are sparse and poorly defined, tending to merge with the granular groundmass, which consists of olivine and pyroxene with minor amounts of maskelynite, nickel-iron, and troilite. Well-preserved fusion crust is present in one edge of the section. A little limonitic staining is present around some of the nickel-iron grains. The section is cut by a dark glassy veinlet, maximum thickness 0.3 mm; clear isotropic material. in this veinlet is tentatively identified as ringwoodite and majorite. Microprobe analyses show olivine (Fa₂₄) and orthopyroxene (Fs₂₀) of uniform composition; the maskelynite has CaO content (2.4%) appropriate to oligoclase composition, but has deficient and variable Na₂O content (2.4-5.0%). The meteorite is classified as an L6 chondrite.  This specimen is identical in texture, mineral compositions, and degree of weathering with RKPA78001, 78003, 79001, and 79002, which evidently are all pieces of a single meteorite.
