Abstract

The invention belongs to the field of geophysical exploration methods, and particularly relates to a comprehensive geophysical method for sedimentary basin uranium resource exploration. The method includes the following steps: in a sedimentary basin for uranium resource exploration, utilizing gravity data to delineate basement relief and determine a depression area; in the depression area, performing aeromagnetic measuring to determine favorable uranium mineralization regions; on the basis of the favorable uranium mineralization regions, carrying out three-dimensional seismic exploration, and delineating distribution characteristics, structural characteristics and inversion-series physical parameters of layers containing mine meshes. By the method, a technical means is provided for sedimentary basin uranium resource evaluation, economic risk of sedimentary basin uranium resource exploration is lowered, and exploration cycle is shortened.

Description
