Name: Meteorite Hills 00433 This is an OFFICIAL meteorite name. Abbreviation: MET 00433 Observed fall: No Year found: 2000 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 10.9 g
Macroscopic Description: Kathleen McBride The exterior of these meteorites is black. The interior is platy and black in color with evaporites and tiny, round, white chondrules.
Thin Section (,2) Descriptions: Tim McCoy and Linda Welzenbach
MET 00431 Cross-Pol. Light
MET 00433 Cross-Pol. Light
The sections consist of a few small chondrules (up to 1 mm), mineral grains and CAIs set in a black matrix. Olivine compositions are Fa0-31, with most less than Fa2, and orthopyroxene is Fs0-7. In thin sections, these meteorites exhibit fracturing and flattening of chondrules along a preferred orientation. The matrix is an iron-rich serpentine which occurs in spheres of ~200 microns in diameter, with each sphere exhibiting a fibrous internal texture. Parting of the meteorites occurs between these spheres. The meteorites are CM2 chondrites
