新疆萨瓦亚尔顿金矿床位于塔里木地台、天山皱褶系、西昆仑皱褶系三大构造单元交汇部位的天山皱褶系南天山锚地槽皱带东阿赖腹背斜中。地质背景和特征与穆龙套金矿床(乌兹别克斯坦)具有类似的特点,因此属于穆龙套型金矿床。通过对该矿床的研究分析,指出该矿的成矿时期为海西晚期-印支期,主要赋存在含碎屑岩建造中(中-上石炭统),矿化的主要因素有构造破碎带、深部的热源循环以及大气降水和地下水渗流的作用。其成矿特点为深部与浅部成分混合特点。
The Savannah Gold Deposit in Xinjiang is located in the Tianshan folds in the intersection of the Tarim platform, the Tianshan fold system, and the West Kunlun fold system in the Tainan antelope anticline in the southern Tianshan Anchorage Belt. Its geological background and characteristics are similar to those of the Murongtao gold deposit (Uzbekistan) and therefore belong to the Mu Longtai type gold deposit. According to the research and analysis of this deposit, it is pointed out that the ore-forming period of this deposit was Late Hercynian-Indosinian, mainly occurring in the middle of the Cretaceous (Middle-Upper Carboniferous). The main factors of mineralization include tectonic fractured zone , Deep heat cycle and the role of atmospheric precipitation and groundwater seepage. Its mineralization is characterized by the mixture of deep and shallow components.
