摘要
青海省域内板块构造体系中的基底隆起带、洋壳沉积带、岛弧隆起带和岩浆岛弧带、陆缘(间)裂谷带、陆缘活动带、弧后(前)盆地等成矿构造环境,其成矿作用具明显的差异性;在板块构造不同演化阶段,形成的矿床组合也各不相同;多期次造山活动的叠加,对各类型矿床的改造作用明显。因此,青海省内各类矿床的形成具有多阶段和多成因的特点。
Within the plate tectonics system of Qinghai province , such The basement uplifted belt, the sedimentary belt of the oceanic crust, the island - arc uplifted belt, the magmatic island - arc belt, the rift belt and the active belt of the continental margin, the back（front） arc basin as the geoglogic environment of metallogenetic structure, there are clear differences in their metallogenesis. During the different evolutionary phase of the plate tectonition , there were different deposit associations. By experiencing the overlape of repeated mountain - making activities, the deposits have the feature of many phases and many genesis of the metallogenesis.
