摘　　要：地壳应力状况主要是由重力和构造作用力引起的 ,本文明确提出“构造附加静水压力”概念 ,指出地壳任一点静水压力是由重力附加静水压力和构造附加静水压力叠合而成 ,构造叠加致使同一地壳深度的水平面上静水压力值不相等 ,这种压力梯度是流体及油气长距离水平运移的主要原因 ;利用成矿深度构造校正测算方法 ,得出胶东“玲珑 -焦家式”金矿成矿深度仅 3km左右的数据 ,进而测得大别超高压变质带含柯石英榴辉岩形成深度仅≥ 32 km,认为可能是壳内构造物理化学过程的产物 ,逐步形成构造物理化学成矿的新认识 ,进而预测了未知区隐伏矿床。The state of crustal strain mainly results from gravity and tectonic process On the basis of the new conception “secondary static water pressure by structure”,it is put forward that static water pressure at any position of the crust is the superimposed product by the gravity secondary static water pressure There are different values of static water pressure of the water surface in same a crustal depth This pressure gradient results from liquid and oil gas migrated horizontally for long distance By means of correction and estimation of metallogenic depth tectonic,the metallogenic depth of 3 kiliometers of “Linglong Jiaojia type”gold deposit,Jiaodong,is obtained,and further obtained forming the depth of coesite bearing in high pressure metamorphy belt in Dabie mountains is more than (or equal )32 kiliometers,which may be the product of physics chemistry process in the crust It is further formed the new knowledges of ore forming by tectonic physics chemistry,and is of significance for prospecting hidden deposit in unknown areas
