 >View Microscope
Fact sheet
Description: 

NWA 10989 was found near the Algeria/Morocco border and acquired as a single stone in 2015. It is a mixed fragmental breccia with a dark fusion crust. The breccia contains mm-sized minerals, lithic and impact melt clasts in a dark brown glassy matrix, in which vesicles can be seen. Accessory minerals include spinel, ilmenite, apatite, merrilite, silica, troilite, kamacite and schreibersite. Evidence for shock is seen in some feldspar grains through recrystallization and partial maskylenisation.

The sample weighed 14.41 grams before analysis and has not been been dated.
