The Naran Tolgoi Gold Deposit is located in the North Kent gold metallogenic belt,the most important gold belt in Mongolia.The ore bodies are hosted in the Lower Cambrian-Upper Ordovician metamorphic sandstone,and occur as vein,vein-like and lenticular type.The alterations are mainly composed of silicification,chloritization,kaolinization and sericitization,in which the silicification is closely associated with gold mineralization.According to assemblage and formation sequence of ore minerals,the ore-forming stages are subpided into 3 stages:quartz-arsenopyrite-pyrite stage,quartz-gold-polymetallic sulfide stage and carbonate stage.Preliminary analysis holds that the Naran Tolgoi Gold Deposit is a hypabyssal medium-low temperature hydrothermal gold deposit controlled by NE-trending fault.
