Abstract
Modelling of migration and accumulation of elements Au and Ag in rocks unde r temperatures of 350-450 degrees C and a 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, chalcop yrite and sphalerite as well as in quartz and muscovite, and get lower in c hlorite, biotite, sericite, albite and calcite, showing that tectono-dynami cs is one of the important factors for petrogenesis and metallogenesis.
