Fact sheet
Description: 

76577 was collected as a rake sample. It is a light tan, vesicular, impact melt rock with a poikilitic texture. Our thin section contains a large single rounded metallic iron clast mantled with troilite. Rotations focus on some of the larger mineral clasts. In places the ilmenite forms dendritic crystals.

The sample weighed 13.5 grams before analysis and has not been dated.

Note: this section is slightly thick.
