Problems solved by technology

[0002] The radon method is an important exploration method in the field of uranium ore exploration. This method indicates that sandstone-type uranium deposits often have the characteristics of "double peak" profile anomalies and low anomalies sandwiched by ring-like anomalies. There are great difficulties in the location and interpretation of deep uranium deposits, and it is difficult to accurately identify and delineate deep uranium deposits

Abstract

The invention relates to a deep sandstone type uranium mineralization information three-dimensional radon anomaly recognition method and system. According to the method, an actually measured radon concentration value of a space point is subjected to three-dimensional gridding processing; calculating the differential radon concentration of each point of the new scatter data; and calculating an unknown deeper differential radon concentration value through nonlinear fitting of vertical differential radon, and realizing deep uranium mineral resource positioning through gridding processing of a newscatter differential radon concentration value and the unknown deeper differential radon concentration value According to trend analysis of abnormality of the three-dimensional contour map after gridding processing. According to the method, the deep uranium ore prospecting accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of uranium prospecting geophysics, in particular to a three-dimensional radon anomaly identification method and system for deep sandstone-type uranium mineralization information. Background technique [0002] The radon method is an important exploration method in the field of uranium ore exploration. This method indicates that sandstone-type uranium deposits often have the characteristics of "double peak" profile anomalies and low anomalies sandwiched by ring-like anomalies. It is difficult to accurately identify and delineate deep uranium deposits. Sandstone-type uranium ore overburden strata are gentle, and the background value of radon concentration in the same stratum changes very little. The local increase and change of radon concentration in the same stratum has a great relationship with the migration of deep radon. The identification and delineation of abnormal mineralization information, in order to...
