金矿床的构造物理化学成矿理论问题探讨

Discussion on metallogenetic theoretical problem of tectophysico-chemistry of gold deposits

构造物理化学是研究地壳物质受构造作用产生的物理和化学变化相互关联的学科。构造物理化学关注构造作用产生或引起的压力、温度和其他物理化学条件变化及其对各种化学平衡的影响。金的成矿作用与构造物理化学环境密切相关,金的构造物理化学成矿研究涉及到构造体制下矿源岩系演化序列,构造动力热液淬取成矿机制,构造附加动力驱动热液成矿机制,构造应力场转化成矿机制,成矿流体水 岩反应的浓缩成矿机制以及构造物理化学场结构与界面成矿理论。

Tectophysicochemistry is a research area that deals with the interrelations between physical and chemical changes of crustal materials caused by tectonism.Tectophysicochemistry pays close attention to pressure,temperature and other physicalchemical conditions produced or induced by tectonism and studies the influences of additional tectonic parameters on various chemical equilibria.This research not only has great significance for theoretical exploration but also is of great practical value for predicting hidden mineral deposits,constructing the tectonic evolution model for the formation of ultrahighpressure metamorphic rocks and studying the driving force of petroleum migration.So it gradually develops into an independent area of geological science.
