| Abstract: | The Longtoushan gold deposit occurs in a Mesozoic residual volcanic neck.The main strata around the neck are Lianhuashan group of Lower Devonian Series and Huangdongkou group of Cambrian System.Displaying veinlet disseminated type and vein type,the ore bodies are found in the sub-volcanic rock pipe and internal or external contact zone of surronding strata.The wall-rock alteration have tourmalinization,silicification,potassic alteration,pyritization,sericitizetion,kaolinization,and chloritication action.The... |
