The Orientation Sign And Preferential Target Selection In The Gold Mine In Longling Ruili Area

Longling Ruili Area is the most important and also one of Kalin style Gold Mine Area in Yunnan Province .Longling Ruili Big Fault is area controlling-mine and leading-mine structure.And control a series of activities of basics-acidity magma.The most typical gold mine in the area is xtrictly affected by Shangmanggang Shangmanggang Fault is the most Primary structure of sandstone .It belongs to sub-grade of Longling Big Fault .It appears northeast way.The area of mine is 7.5Km lkng and 300-500m oide.It controls the five mine segments of yangshishan, Guanglingpo Shangmanggang,Maiwoba and Guoyuan The total medicated amount of gold resource is 17.5T.This gold deposit is in the second group of carbonate rock and lower sandstone, ashstone of Middle Jurasic system. The red clay gold mine is obviously controlled by Shangmanggang Fault and not in conformity between both,Gold is sucked in rock contained gold in fine granule,The conosion of wall rock of mine body are mainly in silcon,iron pyrites,stibium,cinnabar,carbonate,barite and clay.From characters of the microelement of geochemistry and lanthanon of geochemistry,it appears: the mineral substances are from original Kalin gold mine or original corrosion mineralization;from the red clay type gold mine of geochemistry,it show the Kalin gold mine in oxygenation cincture.both are very close and indivisible.This essay collects all information of geochemistry and first mentions there are three gold becoming cinctures,esoecially Shangmsnggang gold sub-cincture. On the base of these.and Kalin.gold.theory,summarize.the. geological.background, stranm,structume,magma,physical gcography,geochemistry and isotopes etc, of the typical mine area;Analyze the controlling factors of the mine area which are aware of;conclude the geological action and the form reason of gold mine .establish the orientation sign of this gold mine;Compare with American similar gold mine and find its very similar as American Kalin gold mine with similar mineral substance and model of cause of formation .Therefore,therefore,there is a very wide foregrornd to explore in Shangmanggang area .According to this,the preferemial target selection in this area is one exposed area ,one first-grade future area and 3 second-grade future areas.
