Rapid prospecting positioning method applicable to hidden sandstone-type uranium mine

Abstract

The invention belongs to the field of geological exploration and particularly relates to a rapid prospecting positioning method applicable to a hidden sandstone-type uranium mine. By means of the rapid prospecting positioning method, a minerogenic prospect of the hidden sandstone-type uranium mine can be found optimally, efficiently, rapidly and accurately. The rapid prospecting positioning method comprises the steps of finding a favorable uranium metallogenic province band preliminarily; measuring and acquiring a concentration value of radon gas, shallow earthquake data and electromagnetic data; determining a favorable target position; drawing abnormal profile maps and planar contour diagrams of radon gas data and electromagnetic data; performing mineral occurrence projection transformation; establishing a geophysical-geochemical abnormal model and finding an oxidation-reduction transitional zone predicting area; finding oxidation-reduction zone predicting areas in different positions; judging double-overlapped areas of a radon gas abnormal area and a magnetic abnormal area to be a favorable metallogenic prospect target region. The rapid prospecting positioning method based on combination of specific geological and geophysical-geochemical methods is strong in operability and high in evaluation efficiency, research results have objectivity, and therefore, the rapid prospecting positioning method has significant theoretical importance and practical meaning in deepening prospecting methods of the hidden sandstone-type uranium mine and expanding uranium resources in China.

Description

technical field [0001] The invention belongs to the field of geological exploration, and specifically relates to a rapid prospecting and positioning technology method suitable for hidden sandstone-type uranium deposits, in particular to a rapid evaluation of hidden sandstone-type uranium ore-forming ore-prospecting target areas based on effective anomaly combinations of geological, geophysical and geochemical prospecting method. Background technique [0002] Sandstone-type uranium deposits are one of the most important types among the four major types of uranium deposits in my country. The utilization efficiency of geophysical and geochemical prospecting data in previous research work is low, and a clear combination of geophysical and geochemical prospecting methods and procedures have not been provided to effectively indicate the prospecting of uranium deposits. Therefore, an efficient and rapid comprehensive evaluation technology is urgently needed to guide the prospecting ...
