| 摘 要： | 通过对纳日贡玛斑岩钼（铜）矿床的蚀变类型的详细研究，识别了矿床蚀变的3种主要类型：钾硅酸盐化、青磐岩化和长石分解蚀变.前二者为矿区早期形成的蚀变，长石分解蚀变形成于晚期.钾硅酸盐化蚀变主要以黑云母化、钾长石化为特征，青磐岩化以脉状绿泥石、绿帘石、方解石等蚀变矿物的发育为基本特征，长石分解蚀变则发育绢云母、高岭土、方解石、硬石膏等矿物.研究认为矿化与石英-辉钼矿±硬石膏±黄铜矿±黄铁矿脉、辉钼矿±黄铁矿±黄铜矿脉有较为密切的联系.

| Abstract: | The Narigongma porphyry molybdenum(-copper) deposit in Southern Qinghai Province is located in the northern part of Yulong metallogenic belt.Research on the deposit recognizes three types of alteration in the orefield,i.e.K-silicate alteration(biotite-K feldspar),propylitic alteration(chlorite-epidote ± calcite) and feldspar-destructive alteration(sericite ± kaolin ± calcite ± anhydrite).The metallogenesis is closely related to the quartz-molybdenite ± anhydrite ± chalcopyrite ± pyrite vein and molybdenite ± pyrite ± chalcopyrite vein. |
