60626 (5) Aluminous Impactite

Fact sheet
Description: 

60626 is a highly aluminous impact melt rock that was collected as a rake sample near the Lunar Module. It has a poikilitic texture, but the plagioclase chadocrysts have indistinct boundaries. In appearance and in composition, this rake sample is different from other impact melt rocks. Its fine grain-size make positive identification of the constituent minerals problematic although considerable plagioclase feldspar and minor olivine can be discerned. Only one small crystal of metallic iron was observed.

The sample weighed 15.9 grams before analysis and has not been dated.

Our thin section image shows a sequence of numbers (1-3) that have been scribed on the glass behind the three rock fragments.
