GEOLOGICAL-SEISMIC THREE-DIMENSIONAL PREDICTION METHOD FOR FAVORABLE METALLOGENIC SITE OF SANDSTONE-TYPE URANIUM DEPOSIT

摘要

A geological-seismic three-dimensional prediction method for a favorable metallogenic site of a sandstone-type uranium deposit, comprising: determining an area to be explored and a target layer in the area to be explored; setting a seismic line in the area to be explored, to acquire seismic data of a profile where the seismic line is located; delineating a depression region and a target region in the profile; determining a dip angle of the stratum in the target region and a dip angle of a stratum underlying the target region according to the seismic data, where the stratum underlying the target region is within the depression region; determining a distribution of fractures in the target region and the depression region according to the seismic data; and delineating a uranium deposit metallogenic site in the target region. The present geological-seismic three-dimensional prediction method for a favorable metallogenic site of a sandstone-type uranium deposit can efficiently and accurately predict a distribution area of uranium ore.
