Abstract:The gold mineralization of Zhao-Ye gold metallogenic belt was originated from the migmatitic hydrothemal process in Proterozoic.The source bed-Jiaodong Group was formed initially at late Archaen(2.6-1.9 Ga) .During 1.9-1.4 Ga.it had undergone the migmatization of facial type,thus formed the concentration of gold and partial mineralization.During 190-150Ma, (Indosinian to Yanshanian),there occurred the super-imposition of fracture migmatization of linear type and partial anatectic magmatic hydro-thermal process.The gold again was remobilized, migrated and concentrated, and became the main metallogenic epoch of this belt.In terms of bilayered fractured structural model, the development of brittle and ductile deformation zones or fracture systems in this region demonstrated the genesis of two mineralization types, i.e. the fissure-filling type(correspond to Linglong type)and alteration type (correspond to Jiaojia type).Based on above recognization, the author establishes the metallogenic model of Zhao-Ye gold metallogenic belt.
Keywords:migmatization of facial type  fracture migmatization of  linear  type  bi-layered fractured structural model  fissure-filling type  alteration type  metallogenic model
