Jilin Province The Wangqing County Miantian Xigou Mine Gold-copper Deposit Geological Characteristics And External Forecast

This article based on the to fully digest based on data in the previous system ofgeological, geochemical, genesis and metallogenic regularity of Miantian Xigoumine, on this basis, to synthesize all favorable information, delineationoutprospecting targets. Widely distributed the Miantian xigou Mine intrusive rocks,Variscan interim granodiorite and early Yanshanian granodiorite rocks constitute themain body of the district, the the late Yanshanian intrusive rocks predominantlydykes output, a small amount was rock strains like, mainly diorite porphyry, diorite,granite porphyry dikes occurrence north of the West to the main. The output of goldand copper zone at the contact area of granodiorite and diorite dykes, dykes ofdiorite or granodiorite body Variscan mid-granodiorite and Yanshanian the dioriteporphyry, diorite forms of ore in the area surrounding rock, mineralization age laterthan both. West to the north of the Miantian the Xigou mine constructed andtrending fault structure-based, followed by east-west and north-south trendingstructures, including the NW-trending fault structure for the area, ore-controllingstructure and its associated secondary structure with control toward area orebody.Fracture mineralization majority north west and north east ore-constructed in thefracture is developed or group of fracture intersection lot more favorablemetallogenic environment.
