Abstract
Fluorite is one of the leading economic minerals in Mongolia. The ore reserves of fluorite of the country ranks fourth in the world. The first fluorite occurrence was found in 1933, then first economic fluorite deposit was discovered on 1939. Based on the morphology of major ore bodies, the fluorite deposits could be subdivided into four main types as vein deposits, vein shaped mineralized zones, lenticular bodies and metasomatite ore in carbonate host. Regarding to mineral assemblage and paragenetic sequences, fluorite deposits and occurrences in Mongolia are divided into 3 main types and 10 subtypes. Fluorite deposits and occurrences in Mongolia are mainly distributed at the east and southeast part of country, making wide zone with 200-300 km width and more than 1,100 km in length. This zone continues to northeast direction to the Russian territory and makes one big metallogenic province in the world. Fluorite mineralization of Mongolia shows close relationship with Mesozoic tectonics and magmatic activity.
