| 摘 要： | 北达巴特铜钼矿赋存于酸性次火山．浅成斑岩体中，其矿化作用呈上铜下钼的双层矿化结构模式。蚀变作用可划分为二期：早期蚀变作用发生在主成矿期之前，表现为黑云母化和钾长石化；晚期蚀变作用与铜钼矿化关系密切，主要表现为硅化、绢云母化、水白云母化、伊利石化、萤石化、电气石化及绿帘石化等，其成因类型可确认为斑岩型铜钼矿．

| Abstract: | The Beidabate copper-molybdenum deposit is hosted by a subvolcanic acidic porphyry intrusion. The mineralization forms the double layer configuration model. The copper mineralization mainly occurs in the supergene layer and the molybdenum mineralization mainly occurs in the lower layer. There are two stages of alteration in the Beidabate copper deposit. The early alteration occurred before the main mineralization, and it is represented by biotitization and K-feldsparization. The late alteration is closely related to the copper-molybdenum mineralization and it is represented by silicification, sercitization, hydromuscovitization, illitization, fluoritization, tourmalinization, and epidotization. The Beidabate copper deposit may be a porphyry-type copper-molybdenum deposit. |
