Writeup from AMN 18(2):

Weight (g): 941.6
Meteorite Type: C2 Chondrite
    LON94102 sample

Macroscopic Description: Kathleen McBride
LON94102 consists of one large fragment and one small piece that do not fit together but are definitely pieces of the same carbonaceous chondrite. Approximately 5% of the dull, pitted fusion crust remains on this specimen. The exterior matrix is black and contains numerous small white angular inclusions. Small areas have oxidized to a red-brown color. Fractures that penetrate the interior are numerous. Slickenside-like features are visible on the surface. Evaporite deposit is present. The sample is friable and easily crumbled when trying to obtain a chip for thin sections.

Thin Section (,11) Description: Brian Mason
The section shows a few chondrules, up to 0.6 mm across, some irregular aggregates, and numerous small mineral grains in a black matrix. The mineral grains are almost entirely olivine, near Mg2SiO4 in composition, with a few iron-rich grains. A small amount of pyroxene, near MgSiO3 in composition, is present. The matrix consists largely of iron-rich serpentine. The meteorite is a C2 chondrite. It is very similar to LON94101, and the possibility of pairing should be considered.
