Macroscopic Description: Robbie Marlow Dark black fusion crust almost completely covers QUE93006 but appears as one small patch on 93004. The exterior color of 93004 is greenish-gray. Evaporite deposit is present on 93006. Numerous submillimeter-sized white inclusions were noted in both of these fragments but the matrix of 93004 is black while the matrix of 93006 is dark gray. Both specimens are friable.

Thin Section (QUE93004,3; 93006,2) Description: Brian Mason
The sections are so similar that a single description will suffice; the meteorites are probably paired. They show scattered chondrules, up to 0.6 mm across, a few irregular aggregates, and small mineral grains in a dark brown to black matrix. The minerals are almost entirely olivine near Mg2SiO4 in composition, with a few more iron-rich grains. A little pyroxene near MgSiO3 in composition is present. The matrix appears to consist largely of iron-rich serpentine. The meteorites are a C2 chondrites.
