Writeup

Writeup from AMN 19(1):

Sample No.:	QUE94368
Location:	Queen Alexandra Range
Dimensions (cm):	1.5 x 1.0 x 0.5
Weight (g):	1.2
Meteorite Type:	E5 chondrite

Macroscopic Description: Kathleen McBride
The exterior of QUE94368 is shiny and iridescent. The interior is heavily oxidized and has a sugary texture.

Thin Section (,2) Description: Brian Mason
The section shows numerous chondrules and irregular aggregates, up to 0.6 mm across, and mineral grains in a moderate amount of dark matrix. The matrix contains a minor amount of nickel-iron and sulfides. The chondrules, aggregates, and mineral grains appear to consist entirely of pyroxene. Weathering is extensive, with veinlets and patches of brown limonite throughout the section. Microprobe analyses show that most of the pyroxene is close to MgSiO₃ in composition, but a few more iron-rich grains were analysed. The nickel-iron contains 0.5-0.7% Si. The meteorite is classified as an E5 chondrite.
