Fact sheet
Description: 

60637 is a rake sample from the area near the Lunar Module. It is a typical glass matrix regolith breccia and has been described as a fragmental breccia, although it has all the attributes of compacted lunar soil. Glass shards, lithic fragments and mineral fragments in a seriate grain size distribution are present. Rotation 1 shows a basaltic clast, a shocked plagioclase feldspar clast and a tiny spherical glass bead. A larger, but this time devitrified bead is visible in rotation 2. A further bead of metallic iron (containing sulphide inclusions) is visible in reflected light. 

The sample weighed 8 grams before analysis and has not been dated.
