71135 (28) Ilmenite Basalt
 >View Microscope
Fact sheet
Description: 

The astronauts spotted what appeared to be a contact between two areas of different vesicularity. They hammered off two pieces (71135 and 71136) from one side of the contact and one piece from the other side (71155). 71135 and 71136 are vesicular ilmenite basalts with both freshly broken and exposed surfaces. They are characterized by large sawtooth needles of ilmenite set in a fine-grained intergrown plagioclase-pyroxene matrix. In places the pyroxene is also dendrite-like (rotation 1).

The sample weighed 36.85 grams before analysis and has not been dated.
