Macroscopic Description - Kathleen McBride, Cecilia Satterwhite | |
Exteriors of these meteorites are covered with brown/black fusion crust. The interiors range from dark gray to black in color with heavy oxidation, rust and metal. Some have rusty weathered inclusions and chondrules. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
These sections are similar enough that one description suffices. The sections show an aggregate of chondrules (up to 1 mm), chondrule fragments, and pyroxene grains in a matrix of about 30% metal and sulfide, including daubreelite. Chondrules contain traces of olivine. Microprobe analyses show the olivine is Fa2 and pyroxene is Fs1-12, though most are Fs1. Kamacite contains 2.7 wt. % Si. These meteorites are EH3 chondrites. |
