Abstract

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.
- tectonic-stress corrected pressure,
- depth of metallogenesis,
- Dabie UHPM zone
