Metallogenic Systems of Qinling Orogen

摘要

摘要: 秦岭造山带是一个多旋回复合大陆碰撞造山带, 是我国重要的多金属成矿带之一.自太古代以来秦岭经历了四大构造演化阶段及多种构造体制的转化, 导致了多期构造热事件和成矿作用的发生, 形成了多个构造成矿旋回, 为秦岭金属元素的大规模富集成矿创造了条件.根据构造、建造、成矿作用及矿床组合特征, 从早到晚可将秦岭区域成矿划分为六大成矿系统.其中, 中晚元古代与海相火山岩及岛弧岩浆活动有关的成矿系统、早古生代与海相火山热液有关的成矿系统、海西期与海底热液及岩浆作用有关的成矿系统及中生代与陆内造山体制构造-岩浆活动有关的成矿系统对成矿的贡献最大.成矿系统的叠加是区内大多数大型、超大型矿床形成的前提

Abstract: Qinling is an intracontinental polycyclic complex collision orogen, and also is one of the most important polymetallic ore-forming belts. Qinling had undergone four tectonic stages and many times tectonic system changes and resulted in the multi-period structure-thermal events and ore-forming processes since Archeozoic, the ore-forming course underwent multicyclic tectonometallogenic evolution also. These created the conditions of the metal elements enrichment and to ore content in large scale. The six regional metallogenic systems have been recognized from early to late in Qinling orogen, in which the Meso-Late Proterozoic metallogenic system related to seafloor volcanic and island arc magmatic activity, Early Paleozoic metallogenic system related to seafloor volcanic hydrothermal fluid, the Hercynian period metallogenic system related to hydrothermal fluid and magmatic processes and Mesozoic metallogenic system related to tectonic-magma activity in intracontinental orogenic system, etc, have more contribution. The superposition of different metallogenic systems is the precondition to most large and super-large type deposits.
