Original Classification CO3 Chondrite
Macroscopic Description - Cecilia Satterwhite
This carbonaceous chondrite has 40% of its exterior covered with fractured black fusion crust, frothy in some areas. Areas without fusion crust are gray to black with some brown weathered areas. Some evaporites and small light colored/weathered inclusions/chondrules are visible. The interior matrix is dark gray to black with abundant mm sized white to light gray inclusions. Matrix around the rim is weathered brown.
Thin Section (,2) Description - Cari Corrigan, Linda Welzenbach and Nicole Lunning
The section consists of abundant, small (up to 1 mm) chondrules, chondrule fragments and mineral grains in a dark matrix. Metal and sulfide occur within and rimming the chondrules. Glass within chondrules appears to be very clear/fresh. CAIs are abundant (mostly Type A), and range in size up to 1 mm. AOAs up to 1 mm are present, as well. Olivine ranges in composition from Fa0-39. This is a CO3 chondrite (likely type 3.0-3.2).
