Abstract:
The study areas are characterized by the well developed dome deformation and metamorphism rocks during the Mesozoic orogenic phases, and the rocks in the areas can be divided into two types: igneous nucleus complex and metamorphic nucleus complex. The former is situated in geosynclinal area, showing the evolutional characteristics of dome and glide deformation of pre orogenic stage, contracted and extensional deformation of orogenic and post orogenic phase, and is relative with tellurium deposit greatly. The latter is located in a platform, and its tectonic evolution includes extensional decollement, thrust nappe, strike slip and shear deformation, which play a great role in controlling the formation and distribution of gold deposits in the areas.
