新疆萨日达拉金矿地质特征及成因研究

Geological characteristics and genesis of Saridala gold deposit,Xinjiang

萨日达拉金矿成矿机制于控矿因素和韧性剪切带密切相关,属于典型的韧性剪切带型金矿床。下文当中结合实践,对该矿地质特征以及成矿作用予以详细分析和探讨。通过研究发现,该矿在空间时间以及成因上,和胜利达坂韧性剪切带金矿有着非常紧密的联系,成矿过程具有多物源、多期次、多阶段的特点,热夜活动与韧性剪切变形及其成矿构成了统一的韧性剪切成岩成矿作用过程。针对含金韧性剪切带系统,在垂向方向还是在横向方向上,成矿元素活化迁出的区域主要为强变形区段,含金流体于沉淀成矿最佳部位主要为,低应变-中等应变区域和不同强度应变带的过渡部位,对大型矿床以及矿体寻找有着非常重要的指导作用。

The mineralization mechanism of Saridala gold deposit is closely related to ore controlling factors and ductile shear zone,which belongs to typical ductile shear zone type gold deposit.Combined with practice,the geological characteristics and mineralization of the deposit are analyzed and discussed in detail.Through the study,it is found that the deposit is closely related to the Shengli Daban ductile shear zone gold deposit in space,time and genesis.The ore-forming process is characterized by multi-source,multi-stage and multi-stage.The thermal night activity,ductile shear deformation and mineralization constitute a unified ductile shear diagenesis and mineralization process.For the gold bearing ductile shear zone system,in vertical or horizontal direction,the areas where the ore-forming elements are activated and moved out are mainly the strong deformation section.The best position of gold bearing fluid in precipitation and mineralization is mainly the low strain medium strain region and the transition part of different strength strain zones,which has a very important guiding role in the exploration of large-scale deposits and ore bodies.
