白石嶂矿床成矿地质条件及找矿标志

Ore-forming geological conditions and prospecting criteria of the baishishi deposit

白石嶂矿区归属于环太平洋钼成矿带华南褶皱系钨-铜-钼成矿省,成矿于中生代燕山期。矿床赋存于燕山二期细粒二云母花岗岩株南东端西侧与上三叠-下侏罗统地层的接触带,白石嶂断裂(F19)与杨塘断裂的交汇部位。对成矿地质条件与矿体特征、矿体规模及找矿标志作了较深入的分析,结合粤东地区钼矿成矿特征,总结出本区控矿地质条件与成矿规律,为粤东地区该类矿床的寻找提供理论上的参考。

The Bai Shi Zhang mining area belongs to the Southern China fold system tungsten copper molybdenum metallogenic province in the circum Pacific molybdenum metallogenic belt, and was formed in the Mesozoic Yanshan period. The deposit occurs in the contact zone between the west side of the south east end of the south east end of the southern east end of the Yanshan two fine granitic granite and the upper three-Lower Jurassic strata, and the intersection of the baishishi fault（F19） and the Yang Tang fault. The ore-forming geological conditions and ore body features, ore body scale and ore prospecting criteria are deeply analyzed. The ore controlling geological conditions and metallogenic regularity are summed up in the east of Guangdong Province, which provides a theoretical reference for the prospecting of this type of ore deposits in eastern Guangdong.
