Name: Queen Alexandra Range 94575 This is an OFFICIAL meteorite name. Abbreviation: QUE 94575 Observed fall: No Year found: 1994 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 39.4 g
Macroscopic Description: Roberta Score
This stone is completely weathered, devoid of fusion crust, and any other worthwhile characteristics.
Thin Section (,2) Description: Brian Mason
The section shows abundant chondrules, up to 0.9 mm across, and chondrule fragments in a black matrix which contains about 25% of nickel-iron and troilite. Weathering is extensive, with limonitic staining and areas of brown limonite throughout the section. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa1-22, mean Fa13; pyroxene, Fs12-24. The variability of the olivine and pyroxene compositions indicate type 3, and the abundance of metal H group, so the meteorite is classified as an H3 chondrite (estimated H3.6).
