“…Apparently, thicker relatively continuous sandstone lenses are considerably more conducive to the deposition of sizeable ore bodies than are thin or discontinuous lenses or blanketlike sandstone beds. This is in agreement with ideas expressed by Mullens and Freeman (1957). Thicker sandstone lenses are also relatively favorable in units other than the Salt Wash. Channeling at the base of an ore-bearing unit results in a thickening of the unit and so does a building up or sandpiling effect in the upper part of the unit.…”

“…Isopach data for the Salt Wash Member of the Morrison Formation in the Dominguez Canyon Wilderness Study Area reveal a trend shown first by Craig and others (1955) and by Mullens and Freeman (1957). Total thickness and limestone thickness outline a trough or synclinal feature oriented approximately transverse to ancient flow directions in the Salt Wash Member.…”

“…The source area for the sediments of the Westwater Canyon was southwest of the Grants mineral belt. The proximal deposits of this fluvial system have been truncated by post-Jurassic erosion (Craig, et a!., 1955;Saucier, 1976;and others (Craig, et al, 1955 andMull ens andFreeman, 1957). In both studies it was concluded that the preserved Salt Wash constitutes a fan shaped wedge of sedimentary rocks with its apex in south-central Utah ( Figure 14).…”

Despite considerable scientific research over the past twenty-five years there still remains much speculation and uncertainty concerning the origin of the so-called tabular uranium deposits of the Colorado Plateau. One particular hypothesis suggests that the deposits resulted from geochemical reactions at the interface between a relatively stagnant solution and a dynamic, ore-carrying solution which permeated the host sandstones. The present study was designed to investigate some aspects of this hypothesis, notably the nature of fluid flow and the relations between the ore deposits and the host sandstones.Field studies involved an investigation of the character and origin of the host fluvial sandstones and their contained uranium deposits and an examination of the textural and porosity-permeability patterns in similar Holocene fluvial sand bodies. Data from the Holocene sand bodies was used to construct realistic porous media models. These models were then saturated with a humic acid solution andean aluminum potassium sulfate solution, causing a visible humic acid precipitate to form at the interface of the two fluids. Finally, an existing numerical model was modified and calibrated for use in predicting the shape and location of the interface between the two solutions.
