Study on partial extraction of uranium and associated elements and its application to geochemical prospecting for locating sandstone-type uranium deposit

Based on the theoretic study and the study of field and laboratory methods,a new method of geochemical prospecting——partial extraction of uranium and associated elements has been preliminarily established.This new method has been tested and used as prognostic tool in 2 known sandstone-type uranium districts and 5 unknown areas.Examined by tens of drill holes in above-mentioned unknown areas the new method shows good prospecting and prognostic effect.Preliminary research achievements indicate that it is basically feasible and effective for locating sandstone-type uranium deposits.The method is of good potential in application,and may become one of prospective geochemical prospecting methods for locating sandstone-type uranuim deposits in China.
