14045 (8) Regolith breccia
We would like to thank the following for the use of this sample:
Samples 14041–14046 are fragments from a fractured clod that broke apart when it was collected. 14045 is a blocky, subangular rock with a rough, hackly surface. Glass-lined zap pits occur on all but one surface. The sample is a friable, fine-grained clastic rock with very sparse sub-angular light-coloured clasts in a medium-grey matrix.
The sample weighed 65.2 grams before analysis. It has not been dated.
Our thin section contains many fragments of irregularly-shaped glass of variable colour and composition. A large (0.3 mm) spherical glass globule can be seen in rotation 1. Throughout the section small fragments of anorthositic material are commonly found (see rotation 2 for one of them.
