Abstract

Shihu gold mine belongs to hydrothermal mesothermal type vein deposits.The deposits’ characteristics are primarily determined by the degree of development of ore-controlling fractures and their occurrence.Conducting numerical simulation on the mine field’s tectonic stress field while applying the elastic-plasticity increment method，and in combination with tectonic analysis shows that：Subject to the effect of the torsional pressure stress field，the middle Jurassic mining area formed NW trending and similar SN trending conjugate shear joint system，they are superimposed on the early complex fold，and become the potential ore holding space.The late Jurassic epoch Mapeng intrusion intrudes along the deep fault，and to trace and transform the old tectonic and the new fracture is less.In later magmatic period，the metallogenic hydrothermal takes the deep fault as the channel to move from deep to shallow and from SE to NW，the NW trending joint trend is in conformance with the fluid moving direction，it is in an extensional environment becoming the primary ore holding space and the concentrated metallogenic area.

Key words： tectonic stress; elastic-plastic incremental method; numerical simulation; metallogenic prediction; Shihu gold orefield
