The Pangxidong-Jinshan silver_gold metallogenic belt,located in the border area between Guangdong and Guangxi,include a series of deposits distributed along the Pangxidong-Jinshan fault, The Late Yanshanisn granites in the belt are of Type I. The silver-gold deposits and the granites are closely related to each other, and characterized by very similar trace elements, REE and Pb isotopes and fluid composition. The Late Yanshanian magmatism may have provided part of hydrothermal solution and metallogenic materials for mineralization.
