Fact sheet
Description: 

71565, 71566 and 71567 are coarse-grained, plagioclase-poikilitic ilmenite basalts that were collected as rake samples. They have vugs and vesicles and contain aggregates of ilmenite and pyroxene. Plagioclase plates are intergrown with pyroxene. Large pyroxene grains are sector-zoned and enclose ilmenite and resorbed olivine. Pyroxene zoning includes pigeonite. Minor minerals include zirconolite, tranquillityite, armalcolite, baddeleyite and blebs of metallic iron. Large crinkled areas of silica can be found in the intersitices.

The sample weighed 24.1 grams before analysis and has not been dated.
