A new uranium exploring technical system for secondary development of coalfield data and its prospecting significance: A case study of the ZS coalfield, Erlian basin

As the main mineralization information, high natural gamma anomaly in coalfield lays a foundation for the fast discovery of a series of uranium ores in uranium geological survey. In order to improve efficiency and accuracy of coalfield data's secondary development, the authors chose the exploration of the ZS uranium deposit in Erlian basin as a study case and constructed a new uranium exploring technical system for coalfield data's secondary development. On such a basis, the authors established coalfield's uranium geological survey model of "quaternary" involving "natural gamma anomaly sieving and prospective area forecasting", "drilling verification in situ and geochemical environment discrimination", "isochronous stratigraphic framework establishing and sedimentary system analysis" and "comprehensive study and target localization". This model which provides a new thought and technological route may play an important role in northern China's uranium exploration.
