摘要
南江县水马门铁矿大地构造归属于扬子地块,位于秦岭造山带和四川盆地稳定克拉通之间的前陆褶皱冲断带。通过对前人资料进行收集、整理及研究,而后又对矿区进行实地考察,初步分析了水马门铁矿的地质特征及控矿因素,并主要得出以下结论:矿区内主要出露地层为元古界火地垭群,在构造上主要表现为强烈的压性特征,片理和近南北向的小规模横断层非常发育,岩浆活动较为频繁,围岩蚀变以矽卡岩化为主;主要控矿因素为岩浆岩和断裂构造;经过初步分析认为该区域铁矿为沉积变质经后期热液迭加改造而形成的铁矿床。
The Shuimamen Fe deposit in Nanjiang, Sichuan lies in the foreland fold-and-thrust zone between the Qinling orogenic belt and the Sichuan basin. This paper deals with geological features and ore controls for the Shuimamen Fe deposit. The study indicates that strata exposed in the ore district belongs to the Proterozoic Huodiya Group characterized by development of longitudinal cross faults and magmatism and skarnization and Fe orebodies are controlled by magmatic rock and fracture structure. The Fe deposit is a sedimentogenic metamorphic one.
