Name: Queen Alexandra Range 94366 This is an OFFICIAL meteorite name. Abbreviation: QUE 94366 Observed fall: No Year found: 1994 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 0.8 g
Macroscopic Description: Roberta Score This tiny carbonaceous chondrite is almost totally covered with dull, black fusion crust. There is not much interior material available but what is visible is light gray with troilite and small areas of crystalline material which will be impossible to separate.
Thin Section (,2) Description: Brian Mason The section shows chondrules (up to 1.2 mm across) and irregular granular aggregates in a brown to black semi-translucent matrix. The chondrules and aggregates consist almost entirely of olivine; trace amounts of nickel-iron and troilite are present, mainly within the chondrules. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa1-25, mean Fa6; pyroxene, Fs1-8. The matrix appears to consist largely of iron-rich serpentine or other phyllosilicates. The meteorite is tentatively classified as a C3 chondrite of the Vigarano subtype, although the phyllosilicate matrix suggests C2; in this respect it is similar to Bali (Geochim. Cosmochim. Acta, v. 58, p. 5589, 1994).
