Classification: Iron, IAB-MG
Place/Time: 2008 in Sahara
Mass: >12kg
Petrography: UCLA samples from two masses; in these and in web photos, silicates are common. We examined two sides of a slice with total area 25 cm2. Silicate abundance ~15 vol%, troilite ~1.5 vol%. Kamacite lengths only ~1.5x widths, making width determination uncertain; best estimate 1.6±0.3 mm. Neumann lines abundant. Some silicates contain abundant small metal grains. A few large (3×4 mm) kamacite lamellae with incompletely resorbed taenite.
NOTE: Etched slices covered with Paraloid for protection
Each slice have reheated and recrystalized rim
On few slices I have seen small dark green crystals
