| Abstract:Auriferous shear zones, consisting of ductile shear zones and brittle-ductile shear zones that formed and controlled gold deposits, show conspicuous structural, evolutionary and mineralization characteristics. The ductile shear zone and brittle-ductile shear zone as well as their R.R.P.D.T. fissures make up a multigrade structural system. Commonly being products of multiphase tectonic activity. According to their geometry and kinematics, the auriferous shear zones might be divided into harmonic type and inharmonic type as well as normal fault style, thrust fault style and strike-slip style, their associations being mainly parallel, network and conjugated forms. Shear zones not only serve as the ore-controlling structure, but also play an important role in metallogenesis. The metallogenic source, field, epoch and facies constitute the important dynamic metallogenic mechanism of the auriferous shear zone type gold deposits. A dynamic metallogenic model for this type of deposits has been established On the basis of mineralization zoning and the relationship between metallogenesis and structural setting. |
