This three year project Integrates multiple geologic, geophysical, hydrologic, and geochemical approaches (Figure 1) to assess the role basin-system-scale fluid (H2O, CO2, CH4) migration patterns over 108 years on Cu and U ore mineralization and diagenesis within the Paradox Basin, Utah.
We have assembled a team of geochemists, structural geologists, hydrogeologists, and economic geologists from the University of Arizona and New Mexico Tech as part of this project (Figure 2). We will have monthly team meetings via skype and annual meetings in person in Tucson and Moab.
As part of this project, co-PI Person and his student will developed a cross-sectional paleohydrologic model of the Paradox Basin using RIFT2D. The code will be used to simulate multi-phase fluid flow, heat, solute transport, and groundwater residence times during basin evolution. We will take into account subsidence, sedimentation, uplift, erosion, and salt tectonics during basin evolution (Figure 3).
Simulated fluid flow events associated with the uncompahgre uplift to the east and internal fluid production due (illite-smectite dewatering, oil-gas-CO2 generation) will be compared to modern fluid age dates, salinity patterns and dating of diagenetic cements and Cu-U ore formation (Figure 4).
Person seeks a PhD candidate to assist with the development and implementation of his basin scale hydrogeologic model. The RA will need to assist Person in incorporating the physics of multi-phase fluids flow into RIFT2D. The student will also be tasked with developing data RIFT2D decks representing the structural and paleohydrologic evolution of the Paradox Basin, Utah. Applicants with a quantitative background and experience in Fortran and Matlab programing will be given preference.
