Sample No.: RKPA79002

Location: Reckling Peak

Field No.: 1201

Weight (gms): 203.6

Meteorite Type: L6 Chondrite

Physical Description: Roberta Score

Dull black fusion crust covers parts of three surfaces. One surface is highly polished in the areas where the fusion crust is. Clasts as large as 3 mm in diameter are visible on the exterior and are identical to those seen in RKPA79001. The surface devoid of fusion crust has weathered to brownish-yellow and reddish-brown color. These areas are rough in texture. The interior matrix is whitish-gray in color with oxidation haloes scattered throughout. A small weathering rind was noted. RKPA79001 and RKPA79002 may be pieces of a single meteorite. Dimensions: 8.5 x 5.5 x 3.5 cm.

Petrographic Description: Brian Mason

Chondrules are sparse and poorly defined, tending to merge with the granular groundmass, which consists largely of olivine and pyroxene, with minor amounts of maskelynite, nickel-iron, and troilite; accessory chromite was noted. Veins up to 2 mm thick of fine-grained material appear to contain ringwoodite and majorite. The meteorite is somewhat weathered, with brown limonitic staining in association with nickel-iron grains. Microprobe analyses give the following composition: olivine, Fa24; pyroxene, Fa20; the maskelynite has CaO (2.3%) appropriate to oligoclase composition, but Na2O is low and variable (3.6-6.9%). The meteorite is classified as an L6 chondrite.
