Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) Well formed, closely packed, unequilibrated, glass-bearing chondrules (apparent diameter 940±460 µm, N = 24) are set in a fine grained matrix containing altered kamacite and troilite. One LL7 lithic clast with poikiloblastic texture and no recognizable chondrules is present in the studied thin section. Magnetic susceptibility log χ (× 10-9 m3/kg) = 3.28. Geochemistry: Olivine (Fa18.3±12.1, range Fa2.2-39.8, N = 9), low-Ca pyroxene (Fs6.1±3.7Wo1.0±1.2, range Fs2.2-11.1Wo0.2-2.8, N = 4), kamacite (Ni 2.8-3.2 wt.%, N = 2), taenite (Ni 10.9 wt.%). Classification: Ordinary chondrite (LL3). Specimens: 23.65 g including one polished thin section at PSF; remainder with Mr. J. Whitcomb. | ||||||||||||||||||||||||||||||||
