| 摘 要： | 夹皮沟金矿带位于吉林省东南部桦甸地区。自1820 年发现以来,已累计探明黄金地质储量150 吨左右。该金矿带位于中朝古板块北缘东段与布列亚-佳木斯地块南缘的碰撞对接部位附近。区内发育5 条平行的NW 向含矿构造带,其北端均以锐角交汇于挥发河断裂。有别于前人的研究成果,本文提出夹皮沟金矿带恰好位于高级区与夹皮沟花岗-绿岩带的接触部位,形成以夹皮沟金矿化带为中心的矿化分带。夹皮沟金矿带为中生代成矿,夹皮沟NW 向弧形构造片理化带及其上盘扇状断裂系控制着金矿床的分布。在主要NW 构造带之间,还存在一系列与之平行的次级构造,它们与扇状断裂的交汇点及扇状构造系中的横向应力集中带是金矿化定位的有利部位。

| Abstract: | 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. |
