Fact sheet
Description: 

15119 is a micro-porphyritic basalt with small phenocrysts of olivine set in a groundmass of granular-looking pyroxene enclosed in plagioclase. It was collected as a fragment associated with breccia in a rake sample. Pyroxene and plagioclase compose nearly 90% of the rock. Accessories include ilmenite, metallic iron and troilite. 

The sample weighed 14.1 grams before analysis. It has not been dated.

The mounting resin of this thin section has started to deteriorate and delamination of the rock slice from the glass slide has occurred on the left margin.
