Macroscopic Description - Kathleen McBride | |
This meteorite is a dull brown-black color with oxidation halos. The fusion crust covers 100% of the surface area. The interior is very weathered. It has a fine grained, sugary textured matrix with some metal. It is very rusty. | |
Thin Section Description (,2) - Tim McCoy | |
The section 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 extensive, including weathering veins. Enstatite is Fs0-2. One grain of free silica was analyzed and metal contains ~1.8 wt % Si. The meteorite is an EH4 chondrite. |
