矿区岩浆活动强烈,有从中基性向中性到中酸性演化的特征。成矿母岩为第一次晚期侵入的石英闪长斑岩,与中国同类岩石相比,具a值偏高,Na_2O>K_2O为特点,与菲律宾莱克斯斑岩铜矿成矿母岩(闪长岩)类似。蚀变岩带围绕石英闪长斑岩体分布,蚀变中心为石英—钾长石化带,其外是青盘岩化带,二者间为不甚发育的过渡带—石英绢云母化带,因比,相应的热液活动也可分为三期:高温气成热液期;高中温热液期和中低温热液期。含矿热液为高盐度,其中K、OH~(-1)、Si与Cu、Mo,S等成矿元素呈正消长关系,S来自上地幔或地壳深部。矿化与石英钾长石化带密切,为含钾成矿溶液交待固结岩石,产生钾化,铜的络合物分解,以硫化物形式沉淀成矿。
The magmatic activity in the mining area is intense with the characteristics of evolution from medium to neutral to moderately acidic. The ore-forming parent rock is the first late-intruded quartz diorite porphyrite, which is characterized by high a-value and high Na 2 O> K 2 O compared with the Chinese counterparts in the rest of the country, Feldspar) is similar. The alteration zone surrounds the quartz diorite porphyry body, the alteration center is quartz-potassium feldspath zone, and the outer one is the green-plate rock zone. The transition zone between the two is undeveloped-quartz-silica mica- Due to the ratio, the corresponding hydrothermal activity can also be divided into three phases: high temperature gas into hydrothermal period; high temperature hydrothermal period and low temperature hydrothermal period. The ore-bearing hydrothermal fluids have high salinity, of which K, OH ~ (-1), Si and Cu, Mo, S and other metallogenic elements showed a positive depletion relationship, and S came from the upper mantle or the deep crust. Mineralization and quartz potassium feldspar zone close, for the mineralization of potassium bearing fluid consolidation of rock, resulting in potassium, copper complex decomposition, precipitation of sulfide form of mineralization.
