Accessory minerals of the Far East lithium-fluoric granites as indicators of ore presence

RMS-DPI code:  2014-1-2-0
Scientific session:  M1. Mineralogy and geochemistry of rare and rare earth metals

Abstract - Summary 
(short description):
On the basis of the published and new data concerning granite composition and ore metasomatite from Badzhalsky (Amur River region) and Kujviveem-Pyrkakajsky (Chukotka) ore areas the presence of ore in Pacific Li-F granite is considered. The comparative analysis of rare-metal Li-F granite accessory mineralization as well as tungsten-tin deposits ore mineralization is carried out. The main features of magmagene and hydrothermal mineralization evolution are revealed. Conclusions are drawn on conformity of composition of ore mineralization in zwitter-tourmalinite formation of the Far East and its relationship with Li-F granite accessory mineralization. It is established that magmatic and hydrothermal mineralization are parts of one evolutionary sequence. The assumption of genetic relation between the embedding of Li-F granite in the Far East belt and the formation of the largest deposits of East Asian tin-tungsten zone is put forward. Keywords: accessory and ore minerals, lithium-fluoric granite, leucogranite, zwitter, tourmalinite, tungsten- tin deposits, presence of ore, Far East, Chukotka, Amur River region
