浒坑钨矿床地质特征、成矿规律以及找矿方向

Geological Characteristics, Metallogenic Regularities and Prospecting Direction of Hukeng Tungsten Deposit

浒坑钨业是一个开采60年的老矿山，矿床受区域断裂与花岗岩株及其围岩的联合控制。区域构造一方面控制浒坑岩株的侵位，另一方面拓展容矿裂隙。含钨石英矿脉主要赋存于自接触面往岩体深处300-500m内接触带中，近于垂直接触面发育，在剖面上呈后侧式排列。根据前人的有关资料和浒坑钨矿床近年来勘查成果和采矿实践，分析总结出矿床地质特征和成矿规律新认识。最后，在综合分析成矿条件和找矿成果的基础上，指出围绕浒坑花岗岩体边缘内外接触带，有较好找矿前景。

Hukeng tungsten deposit is jointly controlled by the regional fracture, granite strains and its surrounding rock. Regional structure controls the stock emplacement and expand ore fissure. Tungsten-containing quartz vein mainly occurs in the contact area within 300-500 meters into the deep rock mass in the contact zone, which is close to the vertical interface with sectional rear type arrangement. Geological characteristics and metallogenic regulations are analyzed based on the related data, exploration .results and mining practice. Based on comprehensive analysis of metallogenie conditions and prospecting results, this paper suggests that good ore prospects exist around the edges of the inner and outer contact zones of granite body.
