Lunar crystalline matrix breccia
4.27 billion years old!
almost as old as Earth's Moon itself!
1 stone of 34,4g was found 11th of August 2001
by anonymous finder. Fusion crust absent.
The meteorite is a crystalline matrix feldspathic breccia
consisting of clasts of various lithologies embedded into a fine-grained crystalline matrix. . Very low 10Beand 41Ca concentrations .
The ejection depth was more than 1100 g/cm2 on the Moon. The transition time was 6±2 kyr.
Makroscopic View: Light-brown and white-brown parts, that are transparent at the side and shiny.
We see light Mascelinite which is isotropic (black) in polarisation;
There is a green fine granulate, some pieces show small breccias, some are red (troctolite), consisting of many broken grains;
some of the grains are showing shock-veins.
