A uranium prospecting method for large basins in structurally active areas

Abstract

The invention relates to a method for finding uranium ore in a large basin in a structurally activated area, which comprises the following steps in sequence: 1. Collecting remote sensing data of the research area through satellites; 2. Performing remote sensing image processing on the remote sensing data to obtain remote sensing thematic images; Interpret the geological structure of the remote sensing thematic images to find out the fault block structures enclosed by faults; 4. According to the texture structure and the exposure and deposition of strata on the fault block structures enclosed by faults, judge the fault uplift and fault block structure. 5. Obtain the gravity data, aeromagnetic data, airborne data and geological maps on each fault uplift; 6. Carry out data integration to find out the uranium source conditions, uranium migration conditions and uranium precipitation enrichment at the same time. Seventh, look for granite-type, volcanic rock-type or carbon-silicon mudstone-type uranium mineralization belts on the fault-uplift; look for sandstone-type uranium mineralization belts on the edge of the fault-uplift. The invention narrows the scope of regional ore prospecting, expands the target types of ore prospecting, and improves the accuracy of ore prospecting.

Description

A kind of uranium prospecting method for large basins in structurally active areas Technical field The present invention relates to a kind of method for looking for uranium ore at the large-scale basin of structural activation area, particularly relate to a kind of dwindling The scope of regional ore prospecting expands the target types of ore prospecting and improves the accuracy of ore prospecting for large basins in structural activation areas The best way to find uranium ore. Background technique The target of searching for uranium ore in large-scale basins at home and abroad is mainly sandstone type uranium ore at present, for other types of uranium ore Mine attention is not enough. For sandstone-type uranium deposits, it is generally believed at home and abroad that they are formed under shallow geological processes. The main considerations for uranium prospecting are sedimentary system and interlayer oxidation zone. For large basins in structurally active area...
