Macroscopic Description: Cecilia Satterwhite
The brown exterior of this meteorite has some patches of black fusion crust. The interior consists of weathered black matrix with abundant mm sized light inclusions.

Thin Section (,2) Description: Cari Corrigan, Tim McCoy

MAC 02675 - Reflected Light
Reflected Light
The section consists of 70-80% round, elongate and irregular metal particles typically 100-200 microns in diameter but reaching 1 mm. These particles are separated by terrestrial hydrated iron oxides. Chondrules occupy 20-30% of the rock and occur in similar shapes and sizes as metal. They are fine-grained and dominated by barred, microporphyritic and cryptocrystalline texture. Silicates are iron-poor (Fs1-4). The meteorite is a metal rich chondrite and is similar to QUE 94411.
