Macroscopic Description - Kathleen McBride | |
The exterior of this meteorite is brown with some weathered fusion crust. The interior is the color of mud with some tiny light colored inclusions. | |
Thin Section Description (,2) - Tim McCoy | |
The section consists of abundant small (up to 1 mm) chondrules, chondrule fragments, and mineral grains in a dark matrix. Metal and sulfide occur within and rimming the chondrules. Olivine ranges in composition from Fa1-50, with a continuous range of intermediate compositions and a slight peak at Fa1-5. Two pyroxene analyses range from Fs1-15. The matrix appears to consist largely of Fe-rich olivine. Terrestrial weathering effects are extensive. The meteorite is a CO3 chondrite. Comparison to the criteria of Scott and Jones (1990, GCA, Vol. 54, pp. 2485-2502) suggests a very low petrologic subtype (<3.2). |
