甘肃省岷县闾井-马坞一带地球化学特征及成矿作用类型讨论

Discussion on geochemical characteristics and types of mineralization in the Lujing Mawu area of Minxian County, Gansu Province

研究区构造位于西秦岭复合造山带东昆仑-中南秦岭裂陷海盆系东段,宗务隆山-南中秦岭裂陷盆地中轴部位。该地区矿产资源丰富,优势矿种为Pb、Zn、Au等。矿床的分布与地层、构造-岩浆岩带分布一致,主要受断裂控制,并相对集中于侵入岩周围。本次研究工作针对该区成矿作用类型进行了初步讨论。

The structure of the research area is located in the eastern section of the East Kunlun Middle South Qinling Rift Basin in the West Qinling Composite Orogenic Belt,and in the central axis of the Zongwu Longshan South Middle Qinling Rift Basin.The region is rich in mineral resources,with advantageous minerals such as Pb,Zn,Au,etc.The distribution of mineral deposits is consistent with the distribution of strata,structures,and magmatic rock zones,mainly controlled by faults and relatively concentrated around intrusive rocks.This research work has conducted preliminary discussions on the types of mineralization in the area.
