Pallasites are considered by many to be the most beautiful type of meteorite. They are thought to originate at the core-mantle boundary of differentiated asteroids, where the metallic core meets the lighter rocks of the crust. They were then shattered to space through another meteorite impact, where they travelled for millions of years until they fell on Earth. The Imilac meteorite and its crater were discovered in 1822 by Europeans. It belongs to the main group of pallasite meteorites. Metal is mainly iron and 9.9% Ni, 21.1 ppm Ga, 46.0 ppm Ge, 0.071 ppm Ir.
In this slice olivines are abundant and have a characteristic golden color that allows the light to get through.
