Macroscopic Description: Kathleen McBride, Carol Schwarz, Cecilia Satterwhite

These meteorites have brownish black polygonally fractured fusion crust with iridescent oxidation haloes present. All samples had fractures that penetrated the surface and are very friable. The interiors are steel gray to black, fine-grained, sugary textured, with metal grains visible. Rusty colored oxidation rind is present. Minor rust is present. These meteorites smell like sulfur and have very small light colored chondrules.

The sections consists of an aggregate of small chondrules (most less than 0.5 mm), chondrule fragments and pyroxene grains with metal, troilite, daubreelite and niningerite. Weathering is relatively minor. Enstatite is Fs0.-1. One grain of free silica was analyzed and metal contains ~1.8 wt. % Si. The meteorite is an EH4-5 chondrite.
