Preliminary discussion on geophysical-geochemical methods in prospecting and exploration of sandstone-type uranium deposit

This paper briefly introduces the application status of main geophysical and geochemical methods used in the prospecting and exploration of sandstone-type uranium deposits at home and abroad.According to geologic settings where sandstone-type uranium deposits occur,authors propose some geophysical and geochemical methods suitable for the prospecting and exploration of sandstone-type uranium deposits,and expound their principles,characteristics and prospecting and exploration stages when these methods can be applied,and introduce some prospecting examples as well.Practice of geologic research and prospecting indicates that the key to success of prospecting for sandstone-type uranium deposit is correctly selecting and reasonably matching effective geophysical and geochemical prospecting methods in accordance with specific geological settings.
