| Abstract:The Xianglushan tungsten-ore field is part of the Jiuling-Zhanggongshan W-Sn metallogenic belt in northern Jiangxi Province. Combining the ore field exploration in recent years, this paper researches the ore-controlling factors on the basis of geological background of this ore field. The result
shows that the impure limestone combination in the Upper Sinian and Cambrian strata is closely related to mineralization in the area. Folds are the major
controlling structures in the ore field. Faults and interlayer fracture zones control the ore body position. The Yanshanian magmatic activities provided ore-forming material sources and played an important role in the process of ore fluid migration and deposition. The main ore bodies, hosted in the pyroxene-biotite metamorphic belt, are related to greisenization alteration. This article establishes a metallogenetic model for the Xainghushan tungsten ore field.It may have important guiding significance for the prediction of ore deposit and resources prospecting and exploitation. It can be also used as a reference in searching for similar deposits in the southern margin of the Yangtze Plate. |
