10049 - Fine grained ilmenite basalt
 >View Microscope
Fact sheet
Description: 

10049 is a fine-grained ilmenite basalt (weight 193 grams) that is 3.5 billion years old. It has a granular texture and in places is vesicular to vuggy. An almost spherical vesicle is depicted in rotation 1 of the virtual microscope. Three species (pyroxene, plagioclase feldspar and ilmenite) make up the bulk of the rock and consist of anhedral or subhedral crystals in an interlocking network. The sample also contains rare olivine and a small interstitial component that includes troilite (an iron sulphide) with metallic iron inclusions and glass.
