Shanyang-Zhashui area between Shangxian- Danfeng and Shanyang-Fengzhen fractures tradi-tionally relegate to the South Qinling tectonic belt.Stratums exposed in the area are Middle - Upper Devonian,Carboniferous and minor Precambrian stratums (Wang et al.,2002;Yan et al.,2012).Regional fractures are main EW trended fractures,and some NNW trended fractures also develop in the area.Different size granite and skarn,porphyry Cu deposits (occurrences) develop at the converge part of the fractures.
