Abstract:
On the basis of the experience in evaluating work of tungsten resources potential in Jiangxi Province, authors summarized the main tungsten genetic types, which include magmatic hydrothermal quartz-vein type, granite type, porphyry type, skarn type and greisen type. This study describes the geological characteristics of various typical deposits, analyzes exploration strategy, and predicts the resources potential. A total of 13 tungsten metallogenic prospect areas have been determined using volume method of Au-bearing geological masses to predict tungsten ore resource potential in Jiangxi province. The results show that the quartz-vein type deposits contain up to 5 million tons, the granite type to 2 million tons, the granite type about 160 thousand tons, the skarn type to 3.5 million tons, and the greisen type about 0.5 million tons. Key aspects of prospecting tungsten deposits in Jiangxi should focus on(1)studying metallogenic regularity of tungsten mineralization in north Jiangxi and proposing metallogenic models;(2)strengthening study of deep ore-prospecting theory so as to explore hidden orebodies; and(3)deepening study of other tungsten-bearing deposit types(except quartz-vein type), especially the most prospecting potential type deposits such as Dahutang-type rock-quartz vein type tungsten deposit and Zhuxi skarn-type tungsten and copper deposit, which can be the key direction of future prospecting.
