新疆那拉提成矿带控矿因素及成矿模式

Ore-controlling factors and metallogenic model of Xinjiang Nalati metallogenic belt

新疆那拉提成矿带的控矿因素为层纹状褶皱,由于地质张裂而形成互相个不干扰的不同金属独立矿区,形成断裂带的矿区同时与横向或纵向裂缝互相重叠,形成“矿藻”或深浅不一的“矿团”;新疆那拉提成矿带内发育多条断层区域剪切带,剪切带宽度、长度均不相同,纵横交错在西部赋矿层;通过研究新疆那拉提成矿带成矿模式,结果表明该矿区成矿模式主要为岩浆气液交代模式。通过以上研究,致力于为新疆那拉提成矿带的发展奠定良好的基础。

The ore-controlling factor of Xinjiang’s Nalati metallogenic belt is layered folds.Due to geological cracking,separate metal deposits of different metals that do not interfere with each other are formed.The mines forming the fault zone overlap with lateral or vertical fractures at the same time,forming“mineral algae”"Or"dumps"of varying depths;multiple fault zone shear zones are developed in the Xinjiang Nalati metallogenic belt,and the width and length of the shear zones are different,criss-crossing the ore-forming layers in the west;The metallogenic model of the ore belt shows that the metallogenic model in this mining area is mainly the magmatic gas-liquid metasomatic model.Through the above research,we are devoted to laying a good foundation for the development of Xinjiang Nalati metallogenic belt.
