Writeup from AMN 18(1):
Sample No.: QUE93030
Location: Queen Alexandra Range
Dimensions (cm): 9.2 x 7.0 x 7.4
Weight (g): 896.9
Meteorite Type: H3 Chondrite (estimated H3.6)

QUE93030

Macroscopic Description: Cecilia Satterwhite
QUE93030 is mostly covered with black fusion crust. Some exterior surfaces are pitted; some have oxidation haloes. Areas devoid of fusion crust are brown and small inclusions are visible. Cleaving this chondrite revealed a medium gray matrix with yellowish-brown oxidation uniformly scattered throughout. A thick dark brown oxidation rind is present. Only a few light and dark inclusions are discernible.

Thin Section (,2) Description: Brian Mason
The section shows numerous chondrules (up to 1.5 mm across), chondrule fragments, and mineral grains in a dark brown to black matrix. Nickel-iron grains are abundant in the matrix; troilite is present in lesser amounts. The meteorite is severely weathered. Microprobe analyses show a wide range in olivine and pyroxene compositions: olivine, Fa6-20, mean Fa14; pyroxene, Fs11-17. The variable olivine and pyroxene compositions indicate type 3, and the amount of nickel-iron H group; the meteorite is therefore classified as an H3 chondrite (estimated H3.6).
