Petrography: The meteorite is a melt breccia composed of large black completely molten and recrystallized regions and some few unmelted chondritic clasts. Chondritic clasts are of LL6 type (plagioclase grain size about 70 µm) and contain rare poorly defined relict chondrules. Melt regions contain characteristic FeNi metal and sufide spherules and frequently carry mineral fragments of the host rock.
