Abstract

In the U- and V-bearing sandstones from the Colorado Plateau, coffinite and vanadium clays are located at the interface between detrital quartz grains and quartz overgrowths. Tyuyamunite, which results from recent alteration of U and V mineraIs, also occurs below the quartz overgrowths. Effective porosity at the core- overgrowth interface is demonstrated by resin impregnation. Etching using dil. HF indicates that the detrital grain-quartz overgrowth interface is preferentially corroded. Coffinite and V- bearing clays may have been precipitatcd by dissolution/replacement along the detrital grain-overgrowth interface; this interface may thus be a site for the creation or destruction of microporosity in sandstones.
