Search for Lead-zinc in the Body of Granite Sichuan Agricultural Ge Hill Pb-Zn as an Example

nungo River Hill lead-zinc in the Qinghai-Tibet Burma Indonesia wicked-type structure system and the western edge of the Sichuan-Yunnan north-south tectonic belt interchanges,major occurrence in the Mesozoic Triassic Formation Commission Zagunao contact with the granite body zone and outside the contact zone in the corner of rock,ore strictly controlled by NNW,nearly NS fault control,from the ore body morphology,occurrence,size and grade,ore type,composition and fabric,wall-rock alteration,etc.discussed deposit geological features.The main ore-controlling factors is the strata,faults and magmatic activity,in which faults is the most important ore-controlling factors.Through the ore S,Pb isotope analysis and ore-forming temperature,forming the times studies have shown that ore-forming strata and magmatic rocks from the ore-forming temperature in the low temperature,forming the Yanshan epoch.View that the genesis of the type of hydrothermal deep-source structure ~ and have the characteristics of multi-phase mineralization.At the same time,it summarizes the main indicators for prospecting,for in this type of deposits in the area looking for help.
