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分为三大阶段和三大构造带。 (1)太古—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 ,成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、郯庐断裂滑移及区域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附近中生代花岗岩区。
The dynamical system is the key to the study of gold mineralization, which controls the generation of gold deposits. The crustal evolution and gold mineralization in Jiapigou area are divided into three stages and three tectonic belts by using the thought of metallogenic dynamical system. (1) The Archean-Proterozoic cratonic - marginal mineralization zone of the sliding force system, the Proterozoic cratonic uplift, the extension of the Proterozoic sediments, and the formation of ductile shear zones around the craton, Gold was initially enriched; (2) the extensional and collision between the southern margin of the Hercynian subduction dynamic system and the continent between Siberia and Sino-Korea Plateau and the occurrence of superficial crustal and gold mineralization by the positive and negative dynamical systems; (3) Mesozoic Superimposed tectonic magmatic system metallogenic belt, Mesozoic Pacific plate subduction, Tanlu fault slip and superposition of multistage dynamical systems such as NNE and NW conjugate ore control, magmatic activity and mantle fluid uplift and further enrichment of gold elements Jiapigou gold deposit eventually formed. The range of metallogenic prediction is from the original metamorphic rock area to the Jiapigou fault zone and the Mesozoic granite area on both sides.
