Abstract: | This paper presents numerical investigation on the ore-forming fluid migration driven by
tectonic deformation and thermally-induced buoyancy force in the Chanziping ore district in South
China. A series of numerical scenarios are considered to examine the effect of meteoric water precipitation,
the dip angle of the faults, unconformity surface, and thermal input on the ore genesis. Our computations
reveal that the downward basinal fluid flow driven by extensional stress mixes with the upward
basal fluid driven by the thermal input from depth at the junction of two faults at a temperature of about
200 C, triggering the precipitation of the Chanziping uranium deposit. |
