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