Fact sheet
Description: 

76575 is a different kind of highland breccia compared to most other samples. It is highly aluminous, with a suevite-like texture. It undoubtedly has an impact origin, but didn’t reach the melting point. The sample is polymict and contains dark glassy clasts of breccia in a lighter coloured breccia matrix. Pyroxene and plagioclase feldspar are the major minerals with metallic iron, troilite and ilmenite present in minor amounts. 
The sample weighed 16.2 grams before analysis and has not been dated.
