Macroscopic Description - Cecilia Satterwhite | |
The exterior of this meteorite has some black/brown fusion crust with some rusty oxidation and abundant pits. Interior is a gray matrix with some small inclusions/chondrules of a lighter color and some areas have abundant rust. | |
Thin Section Description (,,2) - Cari Corrigan, Tim McCoy | |
This meteorite consists of individual unmelted mineral grains, fragments and clasts in a matrix of microcrystalline olivine grains, with metal-sulfide blebs, possibly including multiple sulfide phases, throughout. A few relict chondrules/chondrule fragments are present that show signs of micro-melting of their opaque components. Olivine ranges from Fa0-53, and pyroxenes are Fs10-35. Given the heterogeneity, this preliminary assignment should be followed up with more detailed work involving additional thin sections. |
