Name: Queen Alexandra Range 93018 This is an OFFICIAL meteorite name. Abbreviation: QUE 93018 Observed fall: No Year found: 1993 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 1.3 g
Macroscopic Description: Robbie Marlow The exterior of this carbonaceous chondrite has patches of dull black fusion crust. Areas devoid of fusion crust are dull black and porous. The interior matrix is black and fine grained. One millimeter-sized dark clast is visible.
Thin Section (,2) Description: Brian Mason The section shows rare chondrules up to 0.5 mm across, and numerous small silicate grains in a dark brown to black matrix. Most of the chondrules have been converted into brown serpentine. Trace amounts of nickel-iron and troilite are present as minute grains. Olivine is near Mg2SiO4 in composition, with a few more iron-rich grains. The matrix appears to consist largely of iron-rich serpentine. The meteorite is a C2 chondrite; it is very similar to QUE93005, with which it is probably paired.
