Quantitative calculation method of weak structure monoclinic zone interlayer sandstone type uranium mineralization time

The invention belongs to the technical field of sandstone-type uranium mine exploration, and particularly relates to a quantitative calculation method of weak structure monoclinic zone interlayer sandstone type uranium mineralization time, which comprises the following steps: 1, collecting a drilling seismic section, and carrying out apatite fission track test by adopting sandstone samples; 2, solving a distance h1 between a sampling point and two points of a deposition boundary, and measuring a stratum inclination angle theta; 3, assuming that the time for lifting the deposition boundary of the target layer to the denudation receiving time of the earth surface is the initial mineralization action stage, and solving the burial depth hg from the sampling point position to the earth surfaceunder the critical condition; 4, solving the paleo-geothermal gradient DT of the target stratum of the research area in each geological period; 5, calculating the burial temperature T of the samplingpoint when the target stra
