Abstract

This paper describes the stratiform fluorite and fluorite–base-metal mineralization within the Baikal area, Aldan Shield, Sette-Daban Ridge, and Omulyovka uplift in the Kolyma region. It is assumed to have developed in the Bureya, Khanka, and East Chukchi massifs. Fluorite was concentrated in terrigenous–carbonate rocks of the predominant dolomite range, in the shallow shelf zones separated from the open sea by coral reefs. The fluorite accumulation within layers and horizons at the diagenesis stage was followed by its redistribution with the formation of commercial ore bodies at the catagenesis stage. The Baikal stratiform fluorite mineralization is typical for stratiform deposits of fluorite–base-metal ores. The Aldan type occurs as deposits of high-quality fluorite ores in the carbonate cover of the Siberian Platform. The examples of typical deposits are considered and the forecast fluorite resources are estimated.
