14047 (51) Regolith breccia
We would like to thank the following for the use of this sample:
14047 is a blocky, sub-angular rock with about 10% of its surface coated by vesicular glass (not visible in our thin section).The rock is a friable fine-grained clastic rock have a small percentage of sub-angular light clasts in a medium-grey matrix - its a regolith breccia. Abundant brown glass is obvious in thin section - most is agglutinate glass. Lithic fragments (mainly plagioclase-rich granulite) are also common, making up 16% of the sample. Rotations 1 and 2 show some of these fragments.
The sample weighed 242 grams before analysis. It has not been dated.
The mounting resin of this thin section has deteriorated over time and now contains clusters of feathery crystallites within and around the margins of the thin section.
