Mawu Gold Geochemical Characteristics and Ore-controlling Factors and Prospecting Potential of Min Countv, Gansu Province

Mawu gold deposits are located in the east of Min-Li ore belt.Through field geological survey and the 1/10 000 soil geochemical survey,we get rich orebody geological and geochemical data,and analyzed the ore deposit geochemical characteristics.Wall rock alteration is mainly in low and middle temperature hydrothermal alteration,alteration intensity is positively related to the gold mineralization degree.The ore controlling factors were analyzed from the geological strata,structure,magmatic rocks and geochemical features.The prospecting potential was discussed.
