Macroscopic Description - Cari Corrigan, Tim McCoy, Nicole Lunning and Linda Welzenbach
These meteorites are pallasites with common exterior morphology and weathering. They all exhibit a very weathered, rusty exterior with extensive removal of olivine, leaving voids that range in size from a few millimeters to many centimeters. The larger cavities probably resulted from extensive olivine removal during physical and chemical weathering and weathering of any residual metallic matrix. Sections were made from the two largest stones, and since all were found proximal, the smallest was not sectioned.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy, Nicole Lunning and Linda Welzenbach
These meteorites are similar enough to share a description. These slices exhibit fragmental, angular olivine grains ranging in size from 100 microns to 5 cm. Olivine grains exhibit minimal iron oxide staining. Interstitial to these olivine grains are euhedral and irregular chromites, as well as troilite and schreibersite. Olivine is Fa12-13. The meteorites are pallasites, probably members of the main group.
