Analysis of the Characteristics and Resource Potential of Shuangfengling Gold Deposit in Yuli County, Xinjiang Province

Shuangfengling gold deposit is located in the Kuluqtag continental block of the northeastern margin of Tarim plate, adjacent to the Ailbin late Paleozoic residual basin to the north, and central Tarim block to the south. The gold orebody is strictly controlled by stratigraphic lithology, ductile shear zone and vein rock. The ore types include quartz vein type and compound quartz vein-altered rock type. The alteration mainly includes chloritization, limonitization, jarosite, sericite, carbonization, carbonation, and silicification, etc. The metallogenic material of gold mainly comes from metamorphic hydrothermal. The ore bodies are controlled by fracture structure, and the mutiperiodic activities of fracture structure provided the ore with favorable migration and space so as the metallogenic material can rise and migrate along the channel. The hydrothermal process makes the gold element further migrate and carry gold element to favorable areas, thus forming gold mine. This paper describes in details the geological characteristics and ore-controlling factors of Shuangfengling gold deposit, and summarizes five prospecting indicators of prospecting, i.e. gold-bearing quartz vein, mineral, fault structure, surrounding rock alteration and geochemistry. Finally, combined with the characteristics of three ore sections in Shuangfengling gold mine area, the authors predict preliminarily the resource potential of this area.
