Description: 

77035 is an impact melt rock that has partially dissolved the original clasts or welded them into its recrystallized matrix. It has a fine-grained flow-banded matrix and contains several clasts including one large, pristine clast of cataclastic norite (not seen in our thin section). Smaller, additional lithic clasts include dunite, norite and anorthosite. Mineral clasts of olivine, pyroxene and plagioclase feldspar are also common.

The sample weighed 5727 grams before analysis and has not been dated.
