NWA 832 (Morocco) L4 Regolith Breccia (stone) - found 2001
This is a classic example of a regolith breccias: a host material containing broken up, angular clasts of stony material, with their sharp points smoothed by the bombardment of a myriad micrometeoroid impacts at the surface of the parent asteroid from which it came.
The fresh fusion crust and fresh interior suggest that NWA 832 is a relatively recent fall.
