QUE93517; QUE93575; QUE93584; QUE93586
Location: Queen Alexandra Range
Dimensions (cm): 1.2 x 0.9 x 0.4; 1.5 x 0.8 x 0.4; 2.7 x 2.1 x 1.7; 1.0 x 0.8 x 0.4
Weight (g): 0.9; 1.5; 24.3; 0.8
Meteorite Type: Mesosiderite
Macroscopic Description: Carol Schwarz and Robbie Marlow
These weathered, small, angular fragments contain little or no fusion crust and have a dark red-brown color. The smallest two fragments, QUE93517 and 93586, are now entirely embedded in epoxy.

Thin Section (QUE93517,1; 93575,2; 93584,2; 93586,1) Description: Brian Mason
Microprobe analyses of these sections show a wide range of pyroxene compositions (Fs14-57). The meteorites are classified as mesosiderites. They are very similar to the larger mesosiderite QUE86900 (Antarctic Meteorite Newsletter 10(2), 1987), with which they are probably paired.
