AI Technical Summary

Technical Problem

Existing technologies rely on a single geological parameter in the prediction of sandstone-type uranium deposits, resulting in insufficient spatial resolution. This makes it difficult to capture the spatial coupling relationship of multiple ore-controlling factors such as source supply, sedimentary microfacies, and post-alteration alteration, leading to blurred boundaries of the predicted target area and reducing the accuracy and efficiency of uranium exploration.

Method used

By analyzing key ore-controlling factors such as uranium reservoirs, reduced geological bodies, and post-alteration zoning, and using provenance-sedimentary lobes as units, important prospecting indicators are tracked to generate spatial distribution maps of uranium-enriched areas, reconstruct uranium mineralization source-sink models, and improve prediction accuracy and efficiency.

Benefits of technology

It significantly improved the accuracy and efficiency of exploration in sandstone-type uranium-rich areas, clarified the spatial distribution and migration paths of uranium mineralization, and provided precise data support for uranium exploration.
