柿竹园钨矿床,钨元素在夕卡岩中不仅可以形成白钨矿床,而且还可以形成黑钨矿床,两者均具有相当大的规模,构成黑、白钨矿复合型矿床,这在文献中却少先例.因此,探讨夕卡岩中黑钨矿形成的地质地球化学特征,对进一步研究黑钨矿的成矿理论和普查找矿工作等均具有一定的意义. 区域地质概况矿田位于东坡-月枚复式向斜北段扬起部位.矿区内泥盆系余田桥组地层广泛发育.矿区的西北侧沿褶皱、断裂的交汇处有斑状黑云母花岗岩侵入,接触带上形成不连续的“周边状”夕卡岩,
Shizuyuan tungsten deposit, tungsten in skarn can not only form a scheelite, but also can form a wolframite deposit, both of which have a considerable scale, forming black and scheelite composite deposit, which is in the literature There are few precedents.Therefore, to explore the geological geochemical characteristics of Wollastonite in the skarn is of certain significance for the further study of the ore-forming theory of wolframite and the prospecting work of the prospecting.Regional Geological Survey The ore field is located in In the mining area, the Yintanqiao Formation of Devonian is extensively developed, and the northwest side of the mining area invades the porphyritic biotite granites along the junction of folds and faults, resulting in discontinuities in the contact zone The “peripheral” skarn,
