Sample No.: RKPA78003

Location: Reckling Peak

Field No.: Reckling Peak #3

Weight (gms): 1276.0

Meteorite Type: L6 Chondrite


Physical Description:

This sample was found in Antarctica as two individual pieces, which fit together perfectly. All surfaces with the exception of 2 are covered with thin, dull black fusion crust. The surfaces devoid of fusion crust have weathered a deep reddish-brown, as have the two surfaces that fit together. The W butt end has a clast, ~1 cm in diameter, that appears to be troilite. Upon chipping the meteorite to obtain a suitable thermoluminescence sample, the interior of the specimen was exposed, revealing weathered surfaces composed of very dark gray and very light gray matrix material, possibly the result of weathering processes.


Petrographic Description: Brian Mason

This thin section is indistinguishable from that of RKPA78001, both in texture and mineral composition. It contains maskelynite of similar variable composition, and includes a veinlet like that in RKPA78001, again with material tentatively identified as ringwoodite and majorite. The meteorite is an L6 chondrite. RKPA78003 and RKPA78001 are presumably pieces of a single meteorite.
