Fact sheet
Description: 

Most of 14179 is a crystalline matrix breccia. It may be a piece of sample 14303 or 14305 which were returned in the same bag. Some thin sections contain anorthosite clasts but ours shows a clast of troctolitic granulite. The thin section is unusually thick with some feldspar crystals displaying orange birefringence colours.

The sample weighed 3.03 grams before analysis and is 3.97±0.01 billion years old (Ar/Ar).
