Abstract

The invention discloses a research method suitable for characteristics of an interlayer oxidation zone of a sandstone-type uranium deposit. The research method comprises the steps of S01, establishing macro identification criteria for sandstone of each sub-zone of an interlayer oxidation zone of a target stratum in a research area; S02, acquiring samples and conducting a analytical test; S03, establishing geochemical indicators for each sub-zone of the interlayer oxidation zone according to results of the analytical test; and S04, conducting research on characteristics of each spatial sub zone of the interlayer oxidation zone according to the geochemical indicators for each sub-zone of the interlayer oxidation zone. Through research on the geochemical indicators for different sandstone in a known typical ore deposit in the research area, the invention establishes the geochemical indicators for determining oxidation sandstone, mineralization sandstone and native sandstone, and carries out promotion and application to the entire research area to find out spatial distribution characteristics of each sub-zone of the interlayer oxidation zone in the research area, so that the spatial distribution characteristics of each sub-zone of the interlayer oxidation zone in the research area can be more close to the actual situation, thereby providing more useful guidance to prospecting and exploration.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a research method for the characteristics of an oxidation zone between sandstone-type uranium deposits. Background technique [0002] Interlayer oxidation zone sandstone uranium deposits are clamped in permeable sandstone between impermeable rock layers (such as mudstone). As the oxygen-containing pressurized groundwater carrying uranium migrates downward along the permeable sandstone, uranium deposits at the front of the oxidation zone The uranium deposits formed by reduction and precipitation enrichment, interlayer oxidation zone sandstone-type uranium deposits can often form large ore and rich ore, and are the focus of sandstone-type uranium deposit exploration. [0003] Generally, the crustal evolution process experienced in the same area is similar, so there may be multiple ore deposits in the same area. The characteristics of the interlayer oxidation zone of ...
