| 摘 要： | 岩石熔融-岩浆固结过程不仅导致花岗岩的形成,同时造成了副族微量元素的富集,形成不同类型的矿床和矿田.根据成矿元素与氧、硫元素的关系,文中将上述元素形成的矿田分为亲氧元素型、亲硫元素型和氧硫复合型.前者产于花岗岩体内部,成矿与成岩基本同时,矿田的形成主要受控于岩浆分异作用和岩体剥蚀深度;次者产于岩体外部,成岩与成矿具有一...

| Abstract: | In-situ melting(remelting) not only results in formation of granite,but also in enrichment of subgroup elements to form different types of ore-deposits.The subgroup elements include oxyphiles and sulphophiles,and thus the related ore-field can be divided into three types,i.e.of oxyphiles,of sulfophiles and of both composited.The first type that occurred in granite body with the ages similar to that of the host rock is controlled by magmatic differentiation and its appearance depends on the erosion depth of ... |
