Sample No.: MIL 05013
Location: Miller Range
Field No.: 18027
Dimensions (cm):   10.5x7.7x7.8
Weight (g): 1494.6
Meteorite Type: CO3 Chondrite


Macroscopic Description: Cecilia Satterwhite
This fractured carbonaceous chondrite has brown/black fusion crust covering 95% of its exterior surface. Evaporites and oxidation are visible. The interior is black with oxidation and some rusty areas. White specks and some metal are visible.


Thin Section (,2) Description: Tim McCoy and Valerie Reynolds
The meteorite is likely paired with the MIL 03377 pairing group, the original description of which was: The sections consist 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. Olivine ranges in composition from Fa0-55, with a continuous range of intermediate compositions and a slight peak at Fa1-5. Pyroxene is Fs1-2. The meteorites are CO3 chondrites.
