摘　　要：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领域。构造力可以分解为两部分一部分是均应力,指各向相等的应力,它叠加在原有压力之上,并且影响着各种化学反应的平衡,也是成岩、成矿和变质作用的影响因素。另一部分是差应力,固体中受外力作用普遍产生差应力,它引起地壳物质变形,产生各种构造形迹。构造物理化学特别关注构造作用产生或引起的压力、温度及其他的物理化学条件的变化,研究这些构造附加参量对各种化学平衡的影响,逐渐发展成为独立的学科研究领域。Tectophysicochemistry is a research that deals with the interrelations between physical and chemical changes of crustal materials caused by tectonism. A given tectonic force may be resolved into two parts： homogeneous stress and differential stress. Homogeneous stress refers to isotopic pressure, which is superimposed on the original pressure and affects the equilibrium of various chemical reactions. It is also a factor that influences petrogenesis, metallogenesis and metamorphism. Differential stress is commonly produced when external forces act on a given solid body. It may cause deformation of crustal materials and generate various kinds of structural features. Tectophysicochemistry pays special attention to pressure, temperature and other physicochemical 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 mineral deposits.
