| Abstract: | The ore bodies mainly occur in Xiangyang formation (O 1x),lower Ordovician .The structural belts of folds and faults control mineralization.The ore belongs in sulphide type of complex ore.The gold are mainly native ones in submicroscopic and microscopic size,mostly scattering as inclusions in the main Au bearing minerals as arsenopyrite and pyrite.The trace elements of ore bodies are similar to those of ore bearing strata,so ore forming matter is mainly from them while part from mineralized rocks.The compound fluid of underground hot water solution and the postdiagenetic hydrothermal solution leads ore forming matter to migrate,enrich,and form industrial ore bodies.This deposit belongs with the hypabyssal compound hydrothermal type. |
