Writeup

Writeup from AMN 19(1):

Sample No.:	QUE94575
Location:	Queen Alexandra Range
Dimensions (cm):	4.6 x 3.0 x 2.1
Weight (g):	39.4
Meteorite Type:	H3.6 chondrite

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, Fa_1-22, mean Fa₁₃; pyroxene, Fs_12-24. 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).
