摘要
宝山钨多金属矿地处南岭东西向构造岩浆带铅厂南北向断陷带,宝山燕山期花岗岩体侵位于石炭系碳酸盐岩-含钙碎屑岩中,沿接触带形成套筒状夕卡岩蚀变矿化环带。花岗岩内出现浸染状钨钼矿化,岩体顶部接触带产出帽壳状夕卡岩钨多金属矿化,接触带上部产出项圈状夕卡岩钨多金属矿化,接触带下部外侧产出似层状夕卡岩钨钼多金属矿化,接触带深部梓山组底部可能产出叠生富硫化物多金属矿化,接触带外侧构造裂隙有脉状钼铅锌矿化,构成以岩体为中心接触带多个部位矿化的"一体多位"成矿定位模式。
The Baoshan tungsten polymetallic ore deposit is located in Qianchang north-south fracture-sag zone of east-west tectonic magematic belt in Nanling region. Baoshan Yanshanian granite has invaded in carbonates and calcic fragmental rocks of carboniferous system forming cover-columned skarn type of tungsten-molybdenum polymetallic alteration-mineralization ring belt along the contact zone. There probably occurred several kinds of polymetallic mineralization in more different portions of contact zone between the granite and wall rocks, just as description as follows. Disseminated W-Mo inside the granite, shell shaped skarn W-Mo on the top, chaplet shaped skam W upon the zone, stratoid skarn W-Mo outside the down, superposed rich in sulfides on the unconformable face between the system of carboniferous and devonian in the deep, vein shaped Mo-Pb-Zn in structure fissures outside the zone. Thus, a metallogenetic orientation model of One Rock Body More Places has come into being, centered the granite, and mineralized in more portions of the contact zone.
