The invention belongs to the field of
geological exploration of interlayer
oxidation zone sandstone type
uranium ore, and in particular relates to a geophysical and geochemical exploration combinationmethod for delineating a sandstone type
uranium ore prospective area. The geophysical and geochemical exploration
combination method disclosed by the invention comprises the following steps of (1), rapidly locating a sand body by utilizing shallow earthquake; (2), roughly delineating the trend of a
redox front by utilizing geophysical and geochemical exploration of a
stream sediment; (3), delineating a favorable sand body distribution range A, wherein a sand body, which has a certain thickness, good
connectivity and steady top and bottom waterproof
layers, near the
redox front is delineated as the favorable sand body range A; (4), delineating an ore-induced abnormal combination range B by utilizing soil
radon measurement and geophysical and geochemical exploration of the
stream sediment;and (5), delineating the ore prospective area. By means of the geophysical and geochemical exploration
combination method disclosed by the invention, the ore prospective area can be located rapidly and effectively; therefore, drilling can be objective; waste of the unnecessary drilling
workload is reduced as much as possible; the money and the time are saved; and fast breaking of sandstone type
uranium ore
prospecting can be realized.
