红山糜棱岩-超糜棱岩金矿带大地构造背景属天山地槽北天山地向斜褶皱带,位于康古尔与苦水断裂之间狭长的含金韧性剪切带东段北缘;其出露地层为中下石炭统;华力西中晚期的多期次岩浆活动、韧性剪切作用和构造活动叠加形成了一系列金及多金属矿床,已成为新疆东部主要的产金基地;通过对糜棱岩-超糜棱岩带金矿带赋存的金矿床矿床地质特征的研究,并从宏观及微观尺度进行成矿条件分析,发现金的富集与多金属硫化物,尤其是与方铅矿关系密切;主要特征是贫黄铁矿,多金属硫化物少,局部富含方铅矿,金的分布极不均匀;金具有多源性,主要来自岩浆,少量来自围岩;剪切作用多次叠加及强烈糜棱岩化,使金矿物与多金属硫化物多沿糜棱面理及显微裂隙分布,最终导致工业矿体侵位,沿该带形成一系列糜棱岩-超糜棱岩型金矿床。
The Hongshan mylonite-ultramylonite gold belt has a tectonic setting that belongs to the north Tianshan syncline fold belt of the Tianshan Gully and is located in the northern margin of the eastern section of the long, gold-bearing ductile shear zone between the Kanggur and the Kuishui fault. The exposed strata are Middle-Lower Carboniferous. A series of gold and polymetallic deposits formed by multi-stage magmatic activities, ductile shear and tectonic activities superimposed in the middle and late Huali West have become the major gold-producing bases in eastern Xinjiang. Based on the study of the geological characteristics of the gold deposits hosted by the mylonite-ultramylonite belt and the analysis of metallogenic conditions from macroscopic and microscopic scales, it is found that the gold enrichment is related to the accumulation of polymetallic sulphides, especially Which is closely related to galena. The main features are lean pyrite, few polymetallic sulphides, partially galena-rich, extremely uneven distribution of gold; gold has multi-sourced origin mainly from magma and a small amount from surrounding rock; Multiple superimposition of shearing and strong mylonitization led to the distribution of gold minerals and polymetallic sulfides along mylonitic facies and micro-fractures, which finally led to the emplacement of industrial orebodies, forming a series of mylonites along the belt - super mylonite type gold deposit.
