Fact sheet
Description: 

70135 is a vesicular high-Ti basalt typical of the Apollo 17 site. It has been described 70135 as plagioclase-poikilitic. Small olivine grains are found poikitically enclosed in pyroxene and plagioclase. Rare armalcolite is found poikitically enclosed in pyroxene. Silicate melt inclusions occur trapped in ilmenite. Metallic iron and troilite are found in the groundmass. Silica-rich regions are shown in the two rotations.

The sample weighed 446 grams before analysis and has been dated at 3.77±0.06 billion years (Sm/Nd).
