| 摘 要： | 河南光山县千鹅冲矿床属于癍岩型钼矿床。矿床围岩蚀变硅化、钾长石化、黄铁矿化、绢云母化、绿帘及绿泥石化、高岭土化等多叠加出现，强弱不等。其中硅化、钾长石化、绢云母化、黄铁矿化发育较强且与矿化关系密切。研究表明：在岩浆期后的各成矿阶段，石英、钾长石、磁铁矿、辉钼矿、含矿流体等经过充填、沉淀，在岩体上部围岩中形成了多期矿化细脉叠加、范围集中、规模巨大的钼矿体。

| Abstract: | The Qianhechong Mo Deposit in Guangshan, Henan is a porphyry Mo one. The wall-rock alteration is characterized by silicification, potash feldspathization, pyritization, sericitization, epidotization, chloritization and kaolinization. The Mo mineralization was in close relationship with silicification, potash feldspathization, sericitization and pyritization. |
