Sample No.: MAC88100 Location: MacAlpine Hills Dimensions (cm): 8x5.5x3 Field Number: 5745 Weight (g): 177.3 Meteorite Type: C2 chondrite
Macroscopic Description: René Martinez This oriented carbonaceous chondrite is almost entirely covered by black fusion crust. A thin layer of evaporite deposit appears along the fusion crust-interior boundary. The interior is black with no inclusions visible to the naked eye.
Thin Section (,2) Description: Brian Mason The section consists largely (about 80%) of translucent brown isotropic material, with sparse chondrules and many minute mineral grains, mostly olivine with minor pyroxene. Microprobe analyses show olivine and pyroxene compositions near Mg2SiO4 and MgSiO3 respectively, with a few more iron-rich grains. The meteorite is a C2 carbonaceous chondrite. | ||||||||||||||||||||||||
