| 摘 要： | 成岩成矿深度的构造校正测算方法，是从测算压力中先消除构造附加静水压力之后再计算上覆岩石厚度，即成岩成矿深度的方法。该方法建筑在对地壳岩石处于固体应力状态的认识之上，采用弹性固体模型代替静止流体模型，比沿袭至今单纯用压力／密度方法得出的深度更符合于实际情况。该文以胶不玲珑－焦家式金矿床为例，介绍了该方法的理论基础和野外地质研究方法－开展变形岩相形迹填图，在室内利用三维变形和古差应力测量，计算差应力时 |

| Abstract: | The method proposes to calculate the hydrostatic pressure by subtracting the tectonic component from the total pressure at a point in the crust. such a pressure is referred to as a tectonic-stress free pressure or a teetonic-stress corrected prossure. In this paper,the depth of the sold mineralization is calculated as 3.5km~2.5km,and the depth of the formation of the coesite-bearing eclogite,Dabie UHPM zone,China as 32km. Details of the calcuation are given in te text. |
| Keywords: | tectonic-stress corrected pressure depth of metallogenesis Dabie UHPM zone |
