| 摘 要： | 秦岭造山带黑色岩系划分为南、北、中三个带,北带分布于北秦岭,以秦岭杂岩为基底的岛弧火山岩与花岗岩带到二郎坪弧后边缘海盆带,形成于活动大陆边缘类似的沟、弧、盆构造体系,产出沉积-变质-构造-热液改造型镍-钼小型矿床.中带分布于南秦岭北部,环绕岛链古隆起形成深水-半深水滞留断陷局限盆地,发育与热水沉积有关的黑色岩系,赋存沉积轻微改造型超大型钒矿床和沉积-构造-热液改造型大型金-钒矿床.南带分布于南秦岭南部,扬子板块北缘早古生代沉积区局部拉张环境发育裂谷式断陷盆地,发育巨厚的硅质-泥质-重晶石互层岩系,形成沉积改造中型含钼-钒矿床和热水沉积大型毒重石-重晶石矿床等.解剖了秦岭黑色岩系容矿的典型矿床特征与成矿作用,划分了矿床成因类型,建立了黑色岩系容矿的金属矿床成矿系列.

| Abstract: | The black rock series of Qinling orogenic belt can be divided into three parts. The north part is located in north Qinling orogenic belt and is composed of island volcanic rocks, granite zones and Erlangping marginal basins belt, with the Qinling Complex rock as the basement. There exists the trench-arc-basin system similar to the active continental margin as well as some small-sized sedimentary-metamorphic-structural-hydrothermal-reformation type Ni-Mo deposits. The middle part lies in the northern segment... |
