Jiapigou gold belt lies in the southeast Huadian City, Jilin Province. The proved gold reserve within the belt has up to about 150 tonnage since 1820 when it was discovered. Tectonically, the gold belt is near the collision belt of east part of north margin of Zhongchao palaeoplate and Bulieya-Jiamusi terrain. There are five parallel NW-directed metal-bearing structural belts, namely, from west to east is: Wangjiadian gold-silver-bearing belt, Huiquanzhan copper-silver bearing belt, Jiapigou gold belt, Jingyingbie copper-silver bearing belt and Fuerhe stibinite-mercury bearing belt, whose north ends are converged to Huifahe fault with acute angle. Jiapigou gold belt is just located the contact position of Longgang high-grade metamorphic region and Jiapigou greenstone belt. There is metal minertalization zoning centered by Jiapigou gold belt within Jiapigou area. Jiapigou gold belt is mainly composed of eight gold deposits, namely, from north to south is: Banmiaozi, Daxiangou, Beigou, Sandaocha, Sidaocha, Erdaogou-Miaoling, Jiapigou and Bajiazi. More evidences from geology and geochemistry show that the Jiapigou gold belt is formed during Mesozoic, and the gold mineralizations are distributed in the Jiapigou NW-directed arc schistositical belt and sector faults in hanging wall. A series of substructural belts which are between and parallel to those NW-directed structural belts have been identified, the intersection points of the fan faults and the substructural belts, as well as the lateral stress concentric belts of the fan faults is the favorable areas of orebodies position.
