12045 (5) - Ilmenite basalt
 >View Microscope
Fact sheet
Description: 

12045 is comparable to olivine vitrophyre 12008. Like 12008, 12045 has glomerophyric aggregates of early-formed olivine phenocrysts, spinel grains and rare metallic iron droplets. It also has elongate non-skeletal phenocrysts of titanoaugite. These phenocryst assemblages are set in a variolitic groundmass of acicular pyroxene, plagioclase, silica, ilmenite, troilite and metal. The ilmenite is highly skeletal and occurs as parallel sets of thin platelets. Thus 12045 appears to be a more crystalline, less glassy version of 12008.

The sample weighed 63 grams before analysis. It does not appear to have been dated.
