... The Colorado Plateau and specifically the Paradox basin of southeastern Utah, southwestern Colorado, and adjacent states provides a superbly exposed natural laboratory to consider what drives fluid flow in sedimentary basins and what are its manifold consequences for mineral resources. The rich...

Sanford Abstract Qualitative and numerical simulation of regional groundwater flow in the Colorado Plateau during Late Jurassic and Early Cretaceous time has led to a model of uranium deposition in areas of upwelling solutions. Paleogeographic reconstruction shows that surface drainage...

...Robert C. Bates Abstract The literature on the Colorado Plateau U-V deposits before 1944 includes many geologic factors that could have influenced the deposition of the U and V ore-minerals. Maps are drawn showing the relationships between these influencing geologic factors and the ore deposits...

... obliterated the original features. Four hypotheses of uranium emplacement on the Colorado Plateau justify consideration: (1) the hydrothermal theory, (2) the circulatory ground-water theory, (3) the ash-leach theory, and (4) the syngenetic theory. Observations indicate that (1) is most plausible in the light...

...Y. William Isachsen ABSTRACT Most uranium deposits of the Colorado Plateau are restricted to lenticular sandstones and conglomerates, and are characterized by relatively obvious local sedimentary controls. An argument can be made, however, that the areal and regional controls of uranium deposition...
