The primary ruby mineralization in the Kochkar anticlinorium in the Southern Ural Mountains has been investigated in detail (Kisin, 1992).
The corundum is most intensely concentrated in marbles of the Chuksin-Kuchin graben-syncline, to the north and south of which the
Chuksin and
Kuchin ruby placer deposits were explored.
