摘要: 老定沟钼矿位于豫西熊耳山地区，区内岩浆活动频繁，断裂构造发育，具有良好的成矿条件，是我国金、银、钼、铅、锌等有色金属重要成矿带之一.矿化带受北西西向断裂和中酸性侵入体控制，主要有K1、K2两条构造蚀变带，其中K1中的3条工业矿体呈脉状，厚度稳定，Mo品位0.01×10-2~0.48×10-2.北西西向矿化蚀变带是主要的构造找矿标志，硅化、绢云母化是主要的蚀变标志，辉钼矿化、黄铁矿化、黄铜矿化为主要的矿化标志.矿体深部未封闭，找矿前景较好.Abstract: The Laodinggou molybdenum deposit is located in Xiong'ershan area of western Henan Province, which is one of the important metallogenic belts of nonferrous metals such as gold, silver, molybdenum, lead and zinc in China, with frequent magmatic activities, developed fault structures and good mineralization conditions. The mineralized zone is controlled by NWW-trending faults and acid-intermediate intrusive bodies. K1 and K2 are the two main structural alteration zones, of which three industrial orebodies are in veins with stable thickness. The grade of Mo is 0.01×10-2-0.48×10-2. The NWW-trending mineralized alteration zone is a major structural prospecting indicator. Silicification and sericite are the main alteration symbols. Molybdenite, pyrite and chalcopyrite are the main mineralization signs. The orebodies are not closed in deep part, showing a good exploration prospect.
