辽宁河坎子钼多金属矿区地质特征及找矿标志

Geological Features and Prospecting Signs of Mo-Polymetallic Ore Field in Hekanzi

河坎子钼多金属矿区位于喜峰口-凌源多金属成矿带的北东部,成矿与侵位于北东向河坎子向斜的燕山晚期杂岩体具有明显的时空关系和成因联系;形成了黑云母花岗岩与雾迷山组燧石条带白云质灰岩接触带的金铜矿化、黑云母花岗岩中的金矿化及钾长花岗岩体内的斑岩型钼矿化等;通过对矿床地质特征的分析,进一步总结成矿规律,初步认为该区具有良好的找矿前景。

Hekanzi Mo-polymetallic deposit is located in northeast part of Lingyuan-Xifengkou gold ore zone. space-time and genesis, it proved that mineralization was distinctly contact with the later Yanshan period complex-rock mass, that introuded in the northeast＇s Hekanzi-Syncline. Formed contact zones＇Au-Cu-mineralization between Biotite-granite and Dolomitic- limestone of Wumishan- Formation, Biotite- granite＇s gold mineralization, and Porphyry type Mo-mineralization in K-granite. By analyzing geological characters of the deposit, the further genetic laws of the ore is sumed up , and it is considered preliminary that, there is a good prospect in ore-finding .
