| 摘 要： | 弄如日金矿床围岩蚀变类型有黄铁矿化、绢云母化、雄黄化、钠长石化、硅化、碳酸盐化等,其中强硅化、黄铁矿化、雄(雌)黄化与金矿化关系密切。从断裂-岩脉中心向两侧围岩,蚀变强度由强转弱。矿床的形成主要与喜马拉雅期花岗斑岩的侵入活动有关。

| Abstract: | The wall-rock alteration types in the Nongruri gold deposit,Xizang consist dominantly of pyritization,sericifization,realgarization,albitization,silicification and carbonatization,of which intense silicification,pyritization and realgarization(orpimentization) are closely related to gold mineralization.Furthermore,a direct genetic link for the gold deposit is postulated to be associated with the intrusion of the Himalayan granite-porphyry. |
