通过对新疆阿勒泰市萨热阔布金矿床稳定同位素地球化学、流体包裹体地球化学、矿物地球化学、稀土元素地球化学研究表明,该矿床金矿成矿作用与流体关系密切,流体成分具多源特征及多阶段成矿作用。矿床成矿物质为沉积来源,Na+,Ca2+,SO42-,Cl-在成矿过程中对成矿元素的活化、运移和富集起着积极的作用。萨热阔布金矿石英脉或硅化脉大体上可以分为2个温度阶段:180~200℃和140~160℃;第1阶段属于成矿阶段,按稀土元素的富集程度,主要属于轻稀土(LREE)富集型。
Through the study of stable isotope geochemistry, fluid inclusion geochemistry, mineral geochemistry and rare earth element geochemistry of the Sagyaubu gold deposit in Altay, Xinjiang, the mineralization of the gold deposit in this deposit is closely related to the fluid and the fluid composition has multiple sources Characteristics and multi-stage mineralization. The metallogenic material of the deposit is the sedimentary source, and Na +, Ca2 +, SO42- and Cl- play a positive role in the activation, migration and enrichment of metallogenic elements during metallogenesis. The veins or silicification veins of the Saguocubu gold ore can be roughly divided into two temperature stages: 180 ~ 200 ℃ and 140 ~ 160 ℃. The first stage belongs to the ore-forming stage and mainly belongs to the light Rare earth (LREE) enriched.
