南泥湖钼矿田是我国最大的钼矿之一,主要由南泥湖矿区大型斑岩钼矿床、三道庄矿区大型矽卡岩型钼钨矿床、上房矿区大型斑岩钼铁矿床组成。是一个多期多阶段、多成因、多矿种的综合矿床。有关区域和矿床情况以往报导较多,本文仅围绕蚀变和矿化,探讨了矽卡岩化、钾化、石英化与成矿作用的关系,划分蚀变、矿化阶段,确定与成矿作用有关的主要蚀变类型的时空关系。
Nannihu Molybdenum Mine is one of the largest molybdenum mines in China. It consists of a large-scale porphyry molybdenum deposit in Nannihu Mining Area, a large skarn molybdenum-tungsten deposit in Sandaozhuang Mining Area, a large porphyry molybdenum-iron deposit in Shangfang Mining Area composition. Is a multi-stage, multi-genesis, multi-mineral deposits. There are many reports about the regional and ore deposit situation in this area. In this paper, only the relationship between skarnization, potassicization and quartzization and mineralization is discussed around alteration and mineralization, and the alteration and mineralization stages are divided and determined and mineralized The role of the main types of alteration associated with the spatio-temporal relationship.
