Sample No.: DRPA78009

Location: Derrick Peak

Field No.: 302

Weight (gms): 138100.0

Meteorite Type: Iron

 

Physical Description:

This sample was very clean and fresh when recovered in the Antarctica. However, on its arrival in Houston, the sample was somewhat oxidized, though not as severely as DRPA78008. The original overall color was metallic brownish-black, but now parts of this meteorite are reddish brown. The T surface was in contact with the ground at time of recovery. This surface is concave and wavy (the E surface is also wavy). Silvery material is scattered randomly over the T-N-W surface, ten laths cover an area of ~10 sq. cm. Each lath is oblong and from 1 to 4 cm in length. The B and W surfaces contain many regmaglypts, with the deepest being ~4 cm in depth, thus giving these surfaces a very rough appearance. Silvery inclusions (schreibersite?) with high relief and a tabular shape are scattered on this surface. The B surface is the most weathered surface.
