论构造成矿规律及其动力学机制

TECTONOMETALLOGENIC LAWS AND DYNAMIC MECHANISMS

本文在简述构造成矿学概念的演进之后.着重论述了构造成矿的对称性、等距性、递变性和侧向迁聚性等规律,对构造成矿的动力机制进行了初步分析.作者指出.构造动力成矿作用,是构造应力场、构造地球牾场和构造地球化学场的综合作用;构造成矿过程,是构造运动和成矿物质运动的全过程:是一种不断存在物质交换和能量交换的开放体系中的不可逆过程.构造动力作用能促使成矿元素活化.驱动含矿溶液运移.改变成矿的物理化学条件,导致成矿物质聚集.构造成矿动力学机制的研究.是构造成矿学的关键问題.随着构造成矿学研究的深入发展.逐渐形成了构造成矿学的基础理沦系统.

After briefly introducing the tectonometallogenic conception, the author discusses emphatically tectonometallogenic laws, including symmetry, equidistance, progressiveness and lateral migration- concentration laws, and analyses tectonometallogenic dynamic mechanisms. The author shows that tectonometallogenesis is the comprehensive action of tectonic stress field, tectonic geophysical and geochemical fields, Tectonometallogenic process, including tectonic movements and ore-forming material motion, is a unreversible process which occurs in an opening system. Tectonism mobilizes ore-forming elements, drives the migration of ore-bearing fluid, changes the physical-chemical conditions of ore formation and leads the concentration of ore-forming material. Following the development of tectonometallogenic research, the basic tectonometallogenic theory system has been formed gradually.
