纳赤台金矿床位于东昆仑造山带东段中部。矿体受地层和构造共同控制,一般产在断裂破碎带、构造裂隙及节理中。矿床成矿流体盐度为0.82%~13.29%,密度为0.61~0.97 g/cm3;流体包裹体均一温度为195.9~443.1℃;成矿压力80.01 MPa,成矿深度为8.03 km。研究表明,该区中—晚元古代万保沟群碳酸盐地层提供了主要的成矿物质,晚华力西—印支期受构造造山作用影响,岩浆携带成矿流体、成矿物质沿断裂上升侵位,萃取围岩中大量的成矿物质,迁移至断裂破碎带或节理等部位沉淀成矿。总体上,该矿床为受地层和构造共同控制的中低温热液脉型矿床,相当于造山型金矿床系列的中成矿床。
Nachitai gold deposit is located in the eastern Kunlun Mountains orogenic belt in the middle. The ore body is controlled jointly by the stratum and structure, and is generally produced in fractured zone, structural fracture and joint. The salinity of ore-forming fluids is 0.82% ~ 13.29% and the density is 0.61 ~ 0.97 g / cm3. The homogenization temperature of fluid inclusions is 195.9 ~ 443.1 ℃. The metallogenetic pressure is 80.01 MPa and the metallogenic depth is 8.03 km. The study shows that the middle-late Proterozoic Wanbanggou carbonate strata in this area provide the major ore-forming materials, and Late-Warisix-Indosinian was influenced by tectonic orogeny. Magmatic ore-bearing fluids, As the fault rises and empties, a large amount of ore-forming materials are extracted from the surrounding rock and migrate to the fractured zone or jointed parts to deposit and deposit. In general, the deposit is a medium- and low-temperature hydrothermal veins type deposit co-controlled by strata and structures and is equivalent to a moderate-sized ore deposit of the orogenic gold deposit series.
