| 摘 要： | 贵州境内与峨眉地幔柱不同演化阶段有关的矿产初步分为三类,一类是在峨眉地幔柱演化的壳幔相互作用阶段,因地壳隆升于遵义断拱内形成的石炭纪沉积型铝土矿;第二类是在峨眉地幔柱演化的喷发—消退阶段,与玄武岩有直接成因关系的热水沉积型锰、铁锰、含锰菱铁矿,玄武岩铜矿及火山—沉积型硫铁矿等;第三类可能主要于峨眉地幔柱喷发—消退阶段,因壳幔相互作用,地幔热流上升诱发地壳的重熔以及各种地质响应而形成的中-低温热液矿床,还有一些是在喷发-消退阶段后期,与残留在地壳底部的固化地幔柱"活化"有关的中-低温热液矿床。

| Abstract: | The minerals in Guizhou that has relation with the E' mei mantle plume in different evolution stages were divided into three kinds:one is crust and mantle interaction stage,the Carboniferous sedimentary bauxite formed in the Zunyi broken arch because the crustal uplift;second is the eruption and degrade stage, geothermal sedimentary manganese,ferro-manganese,manganese bearing siderite,basalt cooper,volcanosedimentary pyrites that has direct relation with basalt formed;third maybe is eruption and degrade sta... |
