Thin Section Description (,2 and thick section (,4)) - Cari Corrigan, Tim McCoy
This meteorite was examined in a thin section (,2) which contained only silicate material and a thick section (,4) dominated by metal with minor silicates and chromite. As a whole, the meteorite is metal dominated. Silicates are coarse grained, with individual grains reaching up to 3 mm. Pyroxenes exhibit approximately 2 micron scale striations of high birefringence. Chromites reach up to 1.4 mm. The metal exhibits partial swathing kamacite adjacent to silicates and chromite with plessite dominating most of the section. Metal and sulfide inclusions occur within the chromites. Compositionally, olivines are Fa12-13 and pyroxenes are Fs5Wo42-46 and Fs12Wo1. The compositions and texture suggest grouping with the lodranites. However, the metal rich nature of the sample is reminiscent of QUE 93148, which was also originally classified as a lodranite, but may be related to the HEDs or pyroxene pallasites.
