摘    要:动力系统是金成矿作用研究的关键,它控制金矿床产生的始终,运用成矿动力系统思想把夹皮沟区地壳演化和金成矿为三大阶段和三大构造带,(1)太古一元古宙克拉通隆-滑动力系统边缘矿化带,太古宙克拉通隆起,元古宙沉积物拉伸滑断,矿矿动力系统在克拉通周边形成韧性剪切带,金受到初步富集;(2)海西俯冲动力系统南缘矿化带,西伯利亚板块与中朝板块间大陆拉张和碰撞,正反动力系统产生超壳断裂和金矿化;(3)中生代叠加构造岩浆动力系统成矿带,中生代太平洋板块俯冲,反动力系统产生超壳断裂和金矿化;(3)中生代叠加构造岩浆动力系统成矿带,中生代太平洋板块俯冲,反动力系统产生超壳断裂和金矿化;(3)中生代叠加构造岩浆动力系统成矿带,中生代太平洋板块俯冲,郯庐断裂滑称及区域NNE与NW向共轭控矿等多级动力系统叠加,岩浆活动和幔源流体上升及金元素进一步富集等夹皮沟金矿床最终形成,成矿预测范围由原变质岩区进入夹皮沟断裂带上及两侧俯近中生代花岗岩区。

关 键 词:动力系统 碰撞 叠加 金矿床 吉林 成矿作用 矿床地质

Abstract:Dynamic system is the sdudying key in gold metallization. It controls gold deposit forming all the time. Earth evolution and gold metallization in Jiapigou area are divided into three stages and three kinds of tectonic belts with the help of metallogenic dynamic system theory. The first one is the marginal gold mineralizing belt of rising-slipping dynamic system in the Archean-Proterozoic craton. A pair of dynamic system between uplifting Archean craton and extending or slipping Proterozoic sediments formed gold mineralizing ductile shear belts of the craton margin and then gold enriched initially. Dynamic system of the hercynian subduction is the second kind of the south margin mineralizing belt. Continental rift and collision took place between Siberia plate and Chinese-Korea plate. The positive-negative dynamic system formed over earth crust-fault and gold mineralizes.The Mesozoic superimposing tectono-magmatic dynamic system forms the third kind of metallogenic belt. The Mesozoic Pacific plate subduction, TanLu fault slipping , NNE and NW striked conjugate ore-controlling structure form poly-level dynamic system superimposing. Magma activities and mantle origin fluid go up. Gold further enrich. Finally form Jiapigou gold deposit.The limits of metallogenic prognosis are that original metamorphic rock's area enter Jiapigou fault belt and the Mesozoic granite area by both sides of Jiapigou fault.
Keywords:dynamic system  collision and superimposing  gold deposit  Jilin
