摘要
中条山西南段铜镍、铜铁、金矿与中生代中酸性岩浆活动有关,成因类型为高-中低温热液型。矿体严格受断裂构造控制,不同矿产形成与矿源岩有关,铜镍矿、铜铁矿和金矿分别产于变基性侵入岩、变基性火山岩和片麻岩中,构成了中条山西南段中生代构造—岩浆—热液成矿系统。这一成矿系统是同一能量场和流体场、不同矿源场之间耦合的结果。根据成矿系统分析,该区具有很好的找矿前景,预测在不同矿源复合叠加地段,还有铜铁金、铜镍金、铜铁镍矿床产出,地质找矿应部署在中生代中酸性岩体的分布区。
Cu -Ni, Cu -Fe and Au deposits in the southwest part of Zhongtiao Mountain are related with Mesozoic intermediate to acidic magma ac- tivity, and belong high to low temperature hydrothermal type. Orebodies are strictly controlled by regional faulted structure, geneses of different deposits have relationship with ore source rock, such as Cu - Ni deposits hosted in metamorphic basic intrusive rock, Cu - Fe deposits in metamorphic basic volcanic rock and Au deposits in gneiss. All deposits build Mesozoic structure - magma - hydrothermal metallogenic system in the southwest part of Zhongtiao Mountain. The metallogenic system is the couple results of the same energy field, fluid field and different ore source field, and has good potential for ore The reconnaissance of ore prospecting ought to be arranged in the area where Mesozoic middle - acid magmafic rock is distributed .
