Abstract:
A study of the major fracture zones in the gold-forming area of the Mid-Xuefengshan Mountain has been made by an analysis of the macrostructural features,the microstructural deformation and the tectonogeochemistry.The basic features of these zones and their control of minerogenesis are discussed in this article.The authors point out that the north east-trending ductile-brittle shear zone is the major structure as passageway for ore fluid in the gold-forming area of the Mid-Xuefengshan Mountain and that the north-west-trending fault is an important host structure along which the presently explored gold ore bodies are distributed.
