摘要
火山构造成岩－成矿作用过程中，体系与其环境之间的能量与物质交换，发生各种非线性的不可逆过程。三级火山构造直接控制着矿田（床）的成生。各种作用过程的反应速率和扩散速率不尽相同，造成了元素空间分布的分带性，不同的火山旋回部位和主要控矿、容矿构造，产出了不同的中生代火山矿床，具有一定的旋回－构造地球化学特点，造就了特有的火山矿床成矿模式。
In the course of rock formation and mineralization of volcanic structure, exchange of energy and material between the system and its environment occurs as various non-linear irreversible processes.The third volcanic structure controls the forming of mineral deposits directly.The speed of reaction and proliferation in every process is different,which makes the elements distribution in belts.The different volcanic system positions and the main mineralcontrolling structures have produced the mesozoic volcanic mineral deposits with features of system-structural geochemistry and volcanic mineralization pattern.
