Macroscopic Description - Kathleen McBride, Cecilia Satterwhite | |
Shiny, rusty-black fusion crust of varying amounts, cover the exteriors of these iron meteorites. | |
Thin Section Description - Tim McCoy | |
These 8 meteorites are all paired with each other and with the MET 00400 pairing group. All exhibit the irregular shape and shiny brown surface typical of the MET 00400 irons. All 8 occur along the same ~6 km long linear array at the MET 00400 irons. Slices were removed from MET 00834 and MET 00864, surfaces were polished and etched to reveal the internal structure. Both meteorites exhibited the preterrestrially, heat-altered, medium octahedrite structure typical of the MET 00400 pairing group. The meteorites certainly belong to that group and are probably IIIAB irons. |
