江达构造带源自洋—陆作用的岛弧体制,从晚三叠世以前起经历了陆—陆碰撞焊合、陆内裂谷、陆内造山等多种构造体制的转换,随着印度—欧亚板块的大规模、全面碰撞,陆内裂谷夭折,进入新生代碰撞造山的新阶段。江达构造带在其经历三种体制下都有成矿作用发生,构成三个各具特色的成矿体系。三个成矿体系在同一构造带中历史地叠合,有机组合成一个多元复合的成矿系统,主要的成矿作用发生在陆内裂谷期。
Since the Late Triassic, the Jiangda structural belt has experienced a series of land-continental collision welding, intracontinental rifting and intracontinental orogeny structural transformation. As the Indian - The large-scale and full-scale collision of the Eurasian plate and the intracontinental rift die off, entering a new phase of the Cenozoic collision orogeny. Jiangda structural belt in its experience of three kinds of systems have occurred in the mineralization, constitute three distinctive metallogenic system. The three metallogenic systems are historically superimposed in the same tectonic belt and are organically combined into a multi-component metallogenic system. The main metallogenesis occurred during the intracontinental rifting period.
