GEOCHEMICAL CHARACTERISTICS AND MINERALIZATION SIGNIFICANCE OF THE TAOXIKENG GRANITE IN SOUTHERN JIANGXI PROVINCE, CHINA

Geochemical analyses are carried out on the Taoxikeng granite which is closely related to the economically important Taoxikeng tungsten deposit in Southern Jiangxi Province, South China. The results show that the Taoxikeng granites are characterized by high silicon and aluminum contents and low titanium content. The granites show strong depletion of Eu, Sr and Ba, and enrichment of Th and U. These geochemical characteristics resemble to those of A-type granite, showing well mineralization of tungsten. Combined with the regional data, the authors propose that granitic magmatism played an important role during tungsten mineralization, which provides ore-forming material source for the mineralization and further leads to the formation of Taoxikeng tungsten deposit.
