a shallow-burial mineralization model for the unconformity-related uranium deposits in the athabasca basinModels and ages for the formation of unconformity-associated uranium deposits, notably those in the Athabasca Basin, Canada, and Pine Creek Inlier, Australia, have been much debated. Hoeve and Sibbald ( 1978 ) and Hoeve et al. ( 1980 ) discussed multiple models for the formation of the Canadian uranium deposits, from a magmatic-metamorphic, to ...
بیشترThe Paleoproterozoic Otish Basin, Quebec, hosts several uranium prospects that until recently remained underexplored and poorly understood. In this study, the Camie River U prospect, which shows similar characteristics to high-grade unconformity-related U deposits, is the focus of an integrated basin analysis in the western Otish Basin.92 Energy says the timing is right for a new uranium explorer in a region with "significant opportunity" to uncover new high-grade uranium resources. Athabasca Basin uranium projects. All-up, 92 Energy owns of five projects comprising 21 claims within the Athabasca Basin.
بیشترIn Australia, basin-related uranium mineral systems account for around 21% of uranium resources (Fig. 4). A large contribution of magmatic-related mineral systems (78%) is due to one single deposit, the low-grade but large-tonnage 'supergiant' Olympic Dam deposit. More than 60% of the resources in basin-related systems are associated with ...The review uses the so-called 'source-pathway-trap' paradigm to summarise critical features of fertile mineral systems.

The uranium mineral potential maps were created as part of a wider study to identify exploration targets with high potential for as yet undiscovered unconformity-related uraniumThere are also opportunities to work on other basin-hosted minerals systems, for example the sedimentary copper-cobalt system and the sandstone-type uranium system. Project goals: Better understand geophysical responses from mineral system components comprising the basin-hosted base-metal system

The group is economically significant, collectively containing over 500,000 tonnes of uranium and several examples have been or are being mined. Over a hundred individual deposits are known widely spread over many countries. It is proposed that this group be assigned to a new shear-hosted uranium deposit ...
بیشترA series of theories have been proposed to explain the formation of unconformity-related uranium deposits. However, ore-forming fluid flow mechanisms responsible for uranium mineral precipitation are still not completely understood. In this study, a simplified conceptual model isThe key objectives of and principal steps taken in this study were: (1) development of a process-based, mineral systems-type targeting model for surficial uranium deposits; (2) delineation of areas where the geology is permissive for the existence of surficial uranium deposits (i.e., geologically permissive tracts) using mineral prospectivity ...
بیشترAncient Sedimentary Basin Analysis: As part of a multidisiplinary team headed by Kurt Kyser at Queen's University involved in the analysis of ancient sedimentary basins, I have developed sequence stratigraphic and paleohydrologic models for the sedimentary rocks of basins, such as the Athabasca and Thelon basins of northern Canada, and the Kombolgie Basin of northern Australia.Uranium is a dense metal with the chemical symbol U. As a pure metal, uranium is heavy and metallic. With a specific gravity of about 18.7, natural uranium is nearly as heavy as gold (about 19.3). It is a poor conductor of electricity, malleable, and ductile. Uranium is …
بیشترDetrital uraninite is deposited, together with pyrite and gold, in monomictic (only quartz pebbles) conglomerates that are the basal units of fluvial to lacustrine braided stream systems older than 2.4 Ga. Examples include the Witwatersrand Basin in South Africa, where uranium is mined as a byproduct of gold (0.02 to 0.05 percent uranium grade ...The spectrum of uranium-bearing mineral systems in South Australia and global exploration implications. ... •Hosts two of Australia's three uranium mines, Olympic Dam & Beverley, with a ...

بیشترUranium is a silvery-gray metallic weakly radioactive chemical element.It has the chemical symbol U and atomic number 92. The most common isotopes in natural uranium are 238 U (99.27%) and 235 U (0.72%). All uranium isotopes present in natural uranium are radioactive and fissionable, and 235 U is fissile (will support a neutron-mediated chain reaction). Uranium, thorium, and potassium are the ...Integrated Uranium Resource and Environmental Assessment. The US Geological Survey has assembled a small group of scientists who are assessing the uranium resource potential of the United States. Uranium is used to fuel the 98 operable nuclear reactors in the United States, providing 20% of the nation's electricity.

The fluids involved in these deposits may be derived from metamorphic processes, such as dehydration reactions, or may include fluids which have been equilibrated with metamorphic rocks.
