Sample No:QUE94616
Location:Queen Alexandra Range
Dimensions (cm):3.0 x 2.5 x 1.5
Weight (g):13.6
Meteorite Type:Howardite

Macroscopic Description: Kathleen McBride

The exterior surface of this achondrite is dark gray in color with a small patch of black fusion crust. The exterior has a pebbly texture. The interior reveals a dirty gray matrix with abundant mm-sized white, black and gray inclusions. Minor oxidation is visible.

Thin Section (,2) Description: Brian Mason

The section shows a microbreccia of pyroxene and plagioclase clasts in a comminuted groundmass of these minerals; the groundmass contains a few small grains of opaques. The pyroxene is orthopyroxene with a lesser amount of pigeonite; orthopyroxene clasts are up to 1.5 mm across, whereas pigeonite clasts are smaller. Microprobe analyses show othropyroxene of essentially uniform composition, Wo3Fs24, and a wide range of pigeonite compositions, Wo5-30, Fs17-58. Plagioclase composition is An74-92. Two grains of olivine, Fa59, Fa62, were analyzed. The meteorite is a howardite.
