Lot Essay

First found in 1987, several masses of Zagora have since been recovered; the total known mass is about 50 kg. Silicates are absent in the vast majority of iron meteorites, but many members of the IAB group contain rounded silicate inclusions, sharp-angled fragments and small grains. Whereas most iron meteorites are derived from the molten metal cores of asteroids, the IAB group appears to have formed near the surface of a chondritic asteroid following a large impact. Molten metal and silicate were incompletely separated after the impact event.
