| Abstract: | The external morphologies of Boulder 1, Station 2, and of the four samples taken from it by the Apollo 17 crew, are briefly described. The boulder is a polymict breccia, containing the following principal materials as clasts: gray competent breccias (GCBx), black competent breccias (BCBx), anorthositic breccias (AnBx), pigeonite basalt (PB), coarse norite (CN). All are enclosed in a matrix of light-colored friable breccia (LFBx). |
