Abstract:Chagankunde area in southern margin of Alatau mountains is located in the middle of Alatau W-Sn-Cu-Au-Pb-Zn ore belt in the border area between China and Kazakhstan. Geochemical anomaly with the scale of 1∶50000 has large area, high intensity and obvious concentration center. It has good metallogenic geochemical conditions. Through comprehensive exploration means, such as route geological survey, comprehensive geophysical and geochemical profile survey and trenching engineering disclosure, it is found that on the internal contact zone between granite and sandstone, granite has significant greisenization and local alteration characteristics, such as pyritization, electrification, limonitization and albitization. It is easy to form high temperature hydrothermal greisen tin, rubidium and tungsten deposits with great metallogenic potential. Geological geophysical and geochemical comprehensive method can quickly identify element anomalies and mineralized alteration, and realize rapid evaluation of resource potential in the abnormal area. It has a certain reference significance for regional prospecting.
