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 crustal stress state is mainly caused by gravity and tectonic forces. This paper explicitly puts forward the concept of “constructing additional hydrostatic pressure”, and points out that the hydrostatic pressure at any point of the crust is composed of superimposed hydrostatic pressure by gravity and constructed hydrostatic pressure. The hydrostatic pressure values on the same crustal depth are not equal. This pressure gradient is the main reason for the long-distance fluid and oil migration. Based on the correction calculation method of ore-forming depth, it is concluded that the “Delicate-Jiaojia” gold deposit And the ore-forming depth is only about 3 km. Therefore, the formation depth of the kerogen eclogite in the Dabie UHP metamorphic belt is only ≥32 km, which is considered to be the product of physical and chemical processes in the crust and gradually form the tectonic physicochemical mineralization The new understanding, and then predicted the unknown area of the hidden deposits.
