Macroscopic Description: Cecilia Satterwhite
Black fusion crust covers ninety percent of each of these specimens. Oxidation haloes are present in the fusion crust of 90909. The interior of both specimens is dark brown to black with areas of extensive oxidation. Light and dark inclusions are abundant and range in size from 1 mm to 3 mm.

Thin Section (EET90909,2; 90916,2) Description: Brian Mason
The sections are so similar that a single description suffices; the meteorites are probably paired. Chondrules and chondrule fragments, up to 2.9 mm across, are abundant, and are set in a black matrix which contains a little nickel-iron and troilite. Considerable weathering is indicated by brown limonitic staining throughout the sections. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa1-22, mean Fa12: pyroxene, Fs2-23. The meteorites are classified as L3 chondrites (estimated L3.6).

Black, frothy, pitted, and fractured fusion crust covers most of EET90986. The interior is made up of fine-grained, black matrix with a few shiny inclusions. This sample is extremely friable.

Thin Section (,2) Description: Brian Mason
The section shows chondrules and chondrule fragments, up to 0.9 mm across, and small scattered mineral grains, in a black matrix. The chondrules and chondrule fragments appear to be completely serpentinized. Most of the mineral grains are calcite. The matrix consists largely of iron-rich serpentine, made opaque by carbonaceous matter. The meteorite is a C2 chondrite; it is similar to EET90047 and the possibility of pairing should be considered.

Twenty percent of the exterior of this chondrite is covered with shiny, brown fusion crust. A few small light-colored and heavily weathered inclusions are visible in the dark gray to black matrix. Oxidation is heavy in areas.

Thin Section (,2) Description: Brian Mason
The section consists mostly of chondrules and chondrule fragments up to 2.1 mm across; they consist of granular or radiating pyroxene, sometimes with a little olivine. The opaque material consists largely of nickel-iron with minor sulfides. Minor weathering is indicated by brown staining and occasional limonite areas. The section is partially rimmed with fusion crust. Microprobe analyses show that most of the pyroxene is close to MgSiO3 in composition, but FeO contents up to 2.7% were recorded. The metal contains 0.7-1.1% Si. One grain of plagioclase, An9Or2, was analyzed. The meteorite is classified as an enstatite chondrite, EL3, it is similar to EET90299, and the possibility of pairing should be considered.

Small, dull patches of fusion crust remain on QUE93001 but are gone from 93002. The overall color of the exterior of these two specimens is red-brown. Large and small pyroxene crystals, both green and black in color, are visible on the exterior surfaces. The largest crystal noted in 93001 was 3 x 2 cm in dimension. Numerous fractures penetrate the interior of the specimens making the meteorite easy to break apart. Chipping the specimens revealed an interior that is red-brown, pyroxene-rich, and contains some rounded dark inclusions.

Thin Section (QUE93001,5; 93002,2) Description: Brian Mason
The sections are identical and evidently represent a single meteorite. They show pyroxene and plagioclase clasts, up to 2.4 mm across, in a matrix of nickel-iron and minor troilite (the nickel-iron extensively weathered to limonite). Most of the pyroxene is hypersthene, with composition Wo3Fs24, but a few grains of pigeonite were analyzed. Plagioclase compositions are in the range An90-96. The meteorite is a mesosiderite, and can be confidently paired with QUE86900 (AMN 10(2), 1987).

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.

QUE93005 has dull black fusion crust covering 90% of its exterior. Flow marks are present on all surfaces. Cleaving this specimen revealed a fine-grained, grayish-black interior. Evaporite deposit is present immediately underneath the fusion crust.

Thin Section (,2) Description: Brian Mason
The section shows a few chondrules, up to 0.7 mm across, and numerous small mineral grains in a dark brown to black matrix. Some chondrules consist of granular or porphyritic olivine, but most have been converted to brown serpentine. Fusion crust is present along one edge. Olivine is near Mg2SiO4 in composition, with a few more iron-rich grains. Many of the small mineral grains consist of calcite or ferroan dolomite. The matrix appears to consist largely of iron-rich serpentine. The meteorite is a C2 chondrite.

Macroscopic Description: Robbie Marlow

Macroscopic Description: Cecilia Satterwhite
One patch of black fusion crust remains on this achondrite. One large black inclusion which measures approximately 4 x 2 mm is visible on the exterior surface. The interior is a lighter gray than the exterior and contains numerous 1-2 mm, light and dark inclusions. A minor amount of oxidation is present.

Thin Section (,3) Description: Brian Mason
The section shows a brecciated texture, with angular clasts of pyroxene and plagioclase, up to 0.9 mm across, in a fine-grained comminuted groundmass of these minerals. Microprobe analyses show two distinct pyroxene compositions: orthopyroxene of fairly uniform composition, averaging Wo2Fs25, and pigeonite of variable composition, Wo5-15, Fs40-50. Plagioclase composition ranges from An87 to An94. The presence of the orthopyroxene component indicates that the meteorite can be classified as a howardite.
