Abstract:Exploration over the past two decades indicates that the Paleo-Asian orogenic belts across north
China and Mesozoic-Cenozoic continental basins around their both sides are the most important metallogenic
tectonic domain for the formation of the deposition-type uranium deposits in Paleo-Asian orogenic
belts are essential uranium-rich geological uranium delivery system depends on the transportation
of the surface drainage restricted by basin-mountain coupling -type uranium deposits were
fed by the single uranium source,whereas sandstone-type uranium deposits were fed by the double uranium
source,and the regenerated uranium source originated from uranium reservoirs is quite and
sustained geotectonic background during the dormant period of the trust-orogeny process and the post-fault
thermal subsidence is a period favorable to the formation of depositional-metallogenic -
type uranium deposits need synsedimentary sustained tectonic setting
