| 摘 要： | 阿尔泰诺尔特地区的金矿床(点)主要赋存于下石炭统红山嘴组.区内断裂发育,加里东晚期、华力西中晚期及燕山期花岗岩分布广泛.该区的地壳演化经历了基底陆壳、拉张型过渡壳、汇聚型过渡壳、新陆壳及新陆壳在中生代的发展等阶段.对地层含矿性、元素地球化学特征、成矿流体性质、微量元素及同位素特征等的研究表明,区内金成矿物质主要来源于下石炭统.金成矿为燕山期南北向挤压、构造活化动力学背景下的产物,属于与岩浆活动有关的中低温热液成矿.

| Abstract: | Nurt area of Altay is located in the east of the northern Altay tectonic zone,at the southwest of the Siberia plate.The gold deposits(dots) mainly occur in the Lower Carboniferous Hongshanzui Formation.The main structures are fractures,and the granites formed at late Caledonian stage,middle Hercynian stage.Late Hercynian stage and Yanshanian stage are widely exposed in the Nurt area.The crustal evolution of the Nurt area includes old continental crust stage,transitional crust stage of extensional type,convergent stage,new continental crust stage and new continental crust stage developing in Mesozoic.The studies on the material composition of strata,the characters of geochemistry of elements,the properties of mineralizing fluids,the characters of trace elements and isotopes show that the source materials of the gold deposits(dots) mainly came from the Lower Carboniferous Formation.The gold deposits(dots) are the middle-lower temperature hydrothermal ore deposits(dots) related to magmatism in the Nurt area.At Yanshanian stage,the crust had tectonic activity again because the south plate moved toward the north plate and the gold deposits(dots) were formed at the period. |
