Palladium is almost invariably associated with other platinum metals. The major deposits of rhodium are located in the north of Siberia, in the Ural mountains, in the Ontario region of Canada, and in Transval in South Africa. Other mineral deposits that contain palladium, although of smaller commercial importance, are located in Colombia and Alaska, USA.
Palladium, like all the platinum metals, occurs in volcanic rocks like peridotite or norite. In Siberia, palladium occurs associated to iron, nickel and copper sulfides.
The palladium abundance in the terrestrial crust is about 0,01 grams per ton.
