Writeup from AMN 5(1):

Sample No.: RKPA80225

Location: Reckling Peak

Field No.: 1111

Weight (gms): 8.3

Meteorite Type: L6 Chondrite

 

Physical Description: Roberta Score

Fusion crust covers about half of this stone. The remainder is fracture surface which has been highly weathered. No unweathered material was exposed in chipping. Dimensions: 2.5 x 2 x 1 cm

 

Petrographic Description: Brian Mason

Chondrules are sparse and poorly defined, tending to merge with the granular matrix, which consists of olivine and pyroxene with minor amounts of maskelynite, nickel-iron, and troilite. The section is traversed by a thin (0.05 mm) dark glassy veinlet. Weathering is extensive, with brown limonitic staining throughout the section. Microprobe analyses show olivine (Fa25) and orthopyroxene (Fs21) of uniform composition; the maskelynite has CaO content (2.3%) appropriate to oligoclase composition, but has deficient and variable Na2O content (3.7-5.4%). The meteorite is classified as an L6 chondrite. Apart from a greater degree of weathering this specimen is identical with RKPA78001, 78003, 79001, 79002, and 80202, and probably should be paired with these specimens.
