Fact sheet
Description: 

70035 is a vesicular, medium–grained, hypidiomorphic, granular high-Ti basalt with large anhedral clinopyoxene enclosing armalcolite, ilmenite, ulvöspinel and chrome spinel. The ilmenite content approaches 20%. Interstitial plagioclase encloses ilmenite and olivine. The groundmass includes cristobalite, K-feldspar, tranquillityite, ilmenite, ulvöspinel, troilite and pale brown granitic glass.

Our thin section is a scatter grain sample consisting of mainly pyroxene, plagioclase feldspar and ilmenite.

The sample weighed 5765 grams before analysis and is 3.82±0.06 billion years old (Rb/Sr).
