Fact sheet
Description: 

70185 is a coarse-grained high-Ti mare basalt. It has a granular texture comprising pyroxene and plagioclase feldspar with little olivine and abundant ilmenite. The average grain size is about 0.8 mm. Rotation 1 shows a small cristobalite crystal with a dark brown melt inclusion. Rotation 2 also contains two small cristobalite crystals but is mainly focused on a large pyroxene that displays wavy extinction due to strain.

The sample weighed 466.6 grams before analysis and has not been dated.
