Integrated Remote Sensing Metallogenic Mode of Tanjianshan Gold Deposit In the Northern Marginal Mineralization Belt of Qaidam Basin

The integrated remote sensing prospecting mode can be built through the comprehensive analysis of remote sensing images information,mineralized alteration information,ore formation,ore-control tectonic information,and united intrusive rocks information,geophysical and geochemical unusual information in Tanjianshan goldmine,and guide Mineralization prediction with remote sensing in the northern margin of mineralization belt of Qaidam Basin.The prediction results show that there are good gold metallogenic conditions in integrated remote sensing information in Qinchuangou to Qianmeiling,Wandonggou and Dulonggou.The field verification and sampling tests prove that the Au metal grade purity is 0.30g/t in slate and quartz vein of Tanjianshan group of Ordovician to Silurian in Qinchuangou to Qianm eiling,1.22g/t in quartz veins of andesite and 0.37g/t in m ineralization zone of andesite and tuff of Tanjianshan group of Ordovician to Silurian in Dulonggou,0.48g/t in mineralization zone of andesite and tuff of Tanjianshan group of Ordovician to Silurian in Wandonggou fault zone Therefore,the application of the integrated remote sensing prospecting mode of Tanjianshan goldmine (typical deposit) for remote sensing exploration prediction achieved good results in the northern margin of Qaidam metallogenic belt(the same metallogenic belt).So,this method can be used as a remote sensing prospecting way to generalize and apply in m ineral prediction in the w estern areas,China.
