Abstract
The copper and gold deposits in Dayaoshan area of Guangxi Region occur mainly in Cambrian strata.The Cu-Au mineralization is genetically related to the Caledonian and Yanshanian tectonomagmatic activities.Based on the results of previous geological survey and researches,the metallogenic conditions for the Cu-Au polymetal deposits related to hypabyssal and super-hypabyssal igneous rocks are analyzed from the view of sedimentary formation,magmatic rock,tectonomagmatic activity,ore-forming fluid,trace element and sulfur isotopic characteristics.It is concluded that the deposits in the area genetically belong to sedimentary enrichment-fault structure-hydrothermal overlapping reformation type.The metallogenesis underwent early stage of sedimentary enrichment,middle stage of magmatic hydrothermal overlapping mineralization and end stage of post-magmatic fault and hydrothermal reformation.
