Writeup from AMN 16(2):
Sample No.: MCY92500 Location: Mackay Glacier Dimensions (cm): 2.9 x 2.6 x 2.3 Weight (g): 23.4 Meteorite Type: C2 chondrite
Macroscopic Description: Cecilia Satterwhite Fractured, black fusion crust covers 25% of this carbonaceous chondrite. The interior matrix is fine-grained, medium to dark gray, with abundant small white and gray inclusions. A few chondrules are visible. Oxidation is minor.
Thin Section (.5) Description: Brian Mason The section shows chondrules up to 1.2 mm across, irregular aggregates, and small mineral grains in a black matrix. The minerals are mainly olivine, with minor pyroxene. Olivine compositions are mostly near Mg2SiO4, but occasional iron-rich grains were analyzed, up to Fs40. Pyroxene compositions range from Fs1 to Fs4. The matrix appears to be largely iron-rich serpentine. The meteorite is a C2 Chondrite.
