Sample No.: RKPA78001

Location: Reckling Peak

Field No.: Reckling Peak #1

Weight (gms): 234.9

Meteorite Type: L6 Chondrite


Physical Description:

A thin, dull black fusion crust covers 2 surfaces of this angular sample. The other surfaces are fracture surfaces and are stained reddish-brown by iron oxidation. Several cracks appear to penetrate the specimen. When the sample was cleaved only a very small amount of unweathered material was observed. This material is grayish in color. No inclusions were discernible. Dimensions: 9 x 5 x 4.5 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. One edge is bordered by a small amount of fusion crust. Some limonite is present, usually in association with nickel-iron. The section is cut by a dark glassy veinlet, about 0.05 mm thick; clear isotopic material in this veinlet is tentatively identified as ringwoodite and majorite. Microprobe analyses show olivine (Fa23) and orthopyroxene (Fs20) of uniform composition; the maskelynite has CaO content (2.4%) appropriate to oligoclase composition, but has deficient and variable Na2O content (3.4-6.2%). Accessory merrillite was identified with the microprobe. The meteorite is classified as an L6 chondrite.
