 >View Microscope
Fact sheet
Description: 

70255 is a fine-grained Ti-rich basalt. It is a blocky, subangular, homogeneous basalt with 1-2 % vugs. It contains both olivine (rotation 2) and silica as a consequence of rapid crystallization. Complex compositional zoning and a degree of strain has produced remarkable pyroxene crystals (rotation 1).

The sample weighed 277.2 grams before analysis and has not been dated.
