Name: Queen Alexandra Range 93351 This is an OFFICIAL meteorite name. Abbreviation: QUE 93351 Observed fall: No Year found: 1993 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 4.7 g
Sample No.: QUE93351
Location: Queen Alexandra Range
Dimensions (cm): 1.8 x 1.5 x 0.9
Weight (g): 4.7
Meteorite Type: E3 chondrite
Macroscopic Description: Cecilia Satterwhite
Forty percent of the exterior of this chondrite is covered with brown/black fusion crust. Areas devoid of fusion crust have a polished look. The interior matrix is dark brown to black. Metal is visible. The areas that are oxidized are a yellowish-brown.
Thin Section (,2) Description: Brian Mason
The section shows an aggregate of chondrules and chondrule fragments, up to 1.8 mm across, and mineral grains in a moderate amount of dark matrix. The chondrules and mineral grains consist almost entirely of pyroxene, with possible traces of olivine. The matrix contains a considerable amount of nickel-iron and minor sulfides. 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 analyzed. The nickel-iron contains 0.5-1.1% Si. The meteorite is classified as an E3 chondrite.
