阿尔泰萨热阔布金矿成矿特征及控矿因素

MINERALIZING CHARACTERISTICS AND CONTROLLING FACTORS OF THE SAREKUOBU GOLD DEPOSIT IN ALETAI

萨热阔布金矿既受层位和沉积相控制,又受后期构造—岩浆作用的叠加改造或再造所控制。萨热阔布金矿的形成经历了两个成矿阶段:早期断陷火山—沉积盆地阶段,形成了火山—热水沉积预富集层(有的可富集达到贫矿层)和VHMS型铅锌多金属矿化;晚期(造山过程中)由于构造作用改造和再造,在构造有利部位形成金的工业富集。

The Sarekuobu gold deposit was controlled by the stratigraphic layer, the sediment phase and the superposition enrichment or reconstruction of the late structuremagma activities It was formed through two mineralizing stages: early fault depressional volcanicsediment processes, in which the volcanic exhalation sediment formed the preenrichment layers (some part would be enriched as lean ore layer) and VHMS type leadzinc deposits; late (in the orogenic process) structuremagmatic processes, in which the transform reconstruction made the gold ore bodies deposited in the favorable structural position
