Granite-greenstone terrain in the Dongwufenzi area had undergone threedifferent types of metamorphism. The ductile shear zones not only controlledthe distribution of different metamorphic rock associations, but also resulted inreversed series of regional metamorphic grades. According to the contents ofporphyroclast in rock, the ductile shear metamorphic rocks can be divided intothree groups: mylonitization rock, mylonite and mylonite schist. All of the three group rocks have mylonite texture and deformationtextures can be divided into single mineral type and associated type. A ductileshear metamorphic rock consists of minerals being inuni Variant equilibrium.According to the rock association, characteristic of mylonite texture and recry-stallization in rocks, two different ductile shear metamorphic zones have beenrecognized: Ductile-Brittle type and Brittle-Ductile type, They formed at the different depth of the earth crust and conditions of temperature and pressuredetermined by calculations of coexisting mineral pairs. The results obtainedshow that the gold mineralization, transportion and deposition are related tothe ductile shear metamorphic zones closely.
