- W4252781267 abstract "Two important orebodies have been defined by drilling in the Tallahassee Creek uranium district, Fremont County, Colorado They are the Hansen orebody, which contains about 12 million kg of U3O3, and the Picnic Tree orebody, which contains about I million kg of U3O3. Host rock for the Hansen is the upper Eocene Echo Park Alluvium, and host rock for the Picnic Tree is the lower Oligocene Tallahassee Creek Conglomerate. Average ore grade for both deposits is about 0.08 percent U3O8. The principal source rock for the uranium deposits is the lower Oligocene Wall Mountain Tuff, although a young er volcanic rock, the Oligocene Th1rtynine Mile Andesite, and Precambrian granitic rocks probably also contributed some uranium. Leaching and transportation of the uranium occurred in alkaline oxidizing ground water that developed during alteration of the ash in a semi-arid environment. The uranium was transported in the ground water to favorable sites where 1t was deposited in a reducing environment controlled by carbonaceous material and associated pyrite. Localization of the ore was controlled by ground-water flow conditions and by the distribution of organic mat ter m the host rock. Ground-water flow, which was apparently to the southeast in Echo Park Alluvium that is con fined in the Echo Park graben, was impeded by a fault that offsets the southern end of the graben. This offset prevented efficient discharge into the ancestral Arkansas River drainage and protected chemically reducing areas from destruction by the influx of large amounts of oxidizing ground water. The location of orebodies in the Echo Park Alluvium also may be related to areas where overlying rocks of low permeability were breached by erosion during deposition of the fluvial Tallahassee Creek Conglomerate allowing localized entry of uranium-bearing water. Paleohydrology in Tallahassee Creek Conglomerate may have additionally been controlled by the alteration of pervious ash beds to impervious clay beds." @default.
