This stone is one of many pairings to NWA 5744 & others. It is a granulitic, troctolitic breccia:
-a “troctolite” is a coarse-grained cumulate rock, so it formed pretty deep in a magma chamber (or impact melt sheet): presumably, some of the clasts in this rock match this description
– “granulitic” means that its texture has been partly recrystallized (to granular) by impact heating
This particular lunar is highly shocked, and the dark veins are bottle green when illuminated with a bright light. The single stone “NWA 5744” didn’t have any visible shock veins, but ~all later pairings do. The stones are compositionally ~identical. Pairings total 6+ kilograms: the main mass weighs ~1.6 kilograms.
