Entire exterior is covered with possible fusion crust that is very dark brown-black, rough and has frothy texture in some areas as well as some spots of orange rust. Fresh interior is grey matrix that is mostly rusted to a dark orange-brown with black and metal inclusions throughout. |
The thin section consists of abundant chondrules set in a metal- and sulfide-bearing weathered matrix. Olivine is homogeneous at Fa12 and pyroxene exhibits a small range from Fs9-11. Links to the acapulcoites (GRV 020043) or low-FeO chondrites (such as LAP 04773/04757) should be considered. |
