The Geochemistry of Ore Bone Deposits of the Maikop Sea

摘要

A major part of the Northern Paratethys at the end of the Neogene was a large basin occupying territory from modern Bulgaria to the Aral Sea and called the Maikop Sea, after the oil-bearing Maikop Suite in the Caucasus area. Bones of fish and marine mammals with high U and REE are widely abundant in the bottommost beds of this basin. In some regions this material forms ore deposits in a shape of series of lenses and beds with a thickness up to tens of centimeters. The largest Melovoe deposit located in the southern part of the Mangyshlak Peninsula provided 44 000 tons of uranium for the development of atomic industry and has been exhausted by now [1]. However, there are a
