| 摘 要： | 甘肃省肃南县卡瓦铁矿位于走廊南山地体与托莱山地体的构造结合部位。地层出露较为简单,主要为长城系桦树沟组以及白垩系下沟组,其中长城系桦树沟组为含矿层位。区内构造较为复杂,主要为加里东期形成的褶皱、断层,也有后期的构造。区内的变质作用程度较低,属于低绿片岩相。区内侵入岩主要为超基性岩,基本沿断层分布。总体上卡瓦铁矿与镜铁山铁矿的地质特征极为相似。

| Abstract: | Kawa iron mine in Sunan County of Gansu Province is located in structure combining site of Zoulang south mountain terrain and Tuolai mountain terrain. It includes Huashugou Formation of Changcheng System which contains iron mine and Xiagou Formation cretaceous system. It mainly contains fault and fold of Caledonian. It also contains structure behind of Caledonian. It has low degree of metamorphism-Low greenschist facies. Intrusive rocks are mainly uhrabasic rock which distribute along the fault. Overall Kawa Iron Mine Area and Jingtieshan Iron Mine Area have the similar geological characteristics. |
