    LON94101 sample

Macroscopic Description: Kathleen McBride
LON94101 consists of abundant friable pieces, none of which fit together. This sample contains small (2-3 cm) patches of purplish-red fusion crust. It is black, heavily fractured, and contains green inclusions in the millimeter to centimeter size range. There are also some rusted clasts and small (<1 mm) angular white flecks. The exterior has a greenish tinge where the interior is black. Interior clasts consist of angular tan colored inclusions that are ~3-4 mm in size. Also visible are several rounded white clasts with a sugary texture that are about 3 mm in diameter.

Thin Section (,12 and ,14) Description: Brian Mason
The sections show a few chondrules, up to 0.4 mm across, some irregular aggregates, and numerous small mineral grains in a black matrix. LON94101,12 has two pale green-gray granular enclaves, one 2.9 mm and the other 1.8 mm across. 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 larger enclave consists almost entirely of serpentine, similar in composition to the matrix. The smaller enclave consists largely of enstatite (Fs1-3), with a little olivine (Fa2) and some carbonate grains, both calcite and dolomite. The meteorite is a C2 chondrite.
