| A Study on High-Temperature and High-Pressure Experiment of Correlativity between Deformational System of Au-Bearing Rocks and Element Adjustments |
| Modelling of the migration and accumulation of elements Au and Ag in rocks under temperatures of 350～450℃ and confining pressure of 300 MPa and axial pressure of 100～150 MPa is conducted .It is found that the contents of gold and silver get higher in metallic sulphides such as pyrite,chalcopyrite and sphalerite,as well as quartz,muscorite and get lower in chlorite, muscorite,sericite,biotite,albite and calcite,showing that the tectono_dynamics is one of important factors for petrogenesis and metallogenesis. |
