“…Brannerite is a fairly widespread mineral, known in the ores of hydrothermal and metamorphic uranium deposits as well as in complex gold-uranium deposits (Aleshin et al, 2007;Budyak et al, 2017;Mironov et al, 2008;Tarasov et al, 2018;Cuney et al, 2012;Steacy et al, 1974). However, orthobrannerite, distinguished by the presence of the hydroxyl group in its composition, is less widespread.…”

Abstract— The Buluktaevskoe molybdenum–tungsten deposit is considered a close analog of W–Mo deposits within the large Dzhida orefield, in which the Pervomaiskoe molybdenum and Inkurskoe and Kholtosonskoe tungsten deposits are known. Fifteen ore minerals were identified in the molybdenum ores of the Buluktaevskoe deposit; in addition to molybdenite, they include sulfides (pyrite, galena, and chalcopyrite), tungstates (wolframite and scheelite), molybdates (powellite and wulfenite), and a relatively large number of minerals containing rare earth elements (REE), U, and Th (Th-bearing monazite, brannerite, thorite, and uraninite); among them are previously unknown minerals: fluorine-bearing thorium molybdate and minerals with compositions corresponding to rare mineral species, orthobrannerite and kobeite-(Y). Interrelations and specific chemical compositions of the uranium–thorium–rare earth element minerals are discussed. It was established that these minerals formed in the course of hydrothermal alteration processes, at the early (molybdenite) development stage of the Buluktaevskoe molybdenum–tungsten deposit.

Uranium Deposits Capped by Permafrost Seen as Natural Analogues of a Geological Repository Considering the Upcoming Climate Cooling Period

The article evaluates the conditions at the site proposed for a geological radioactive waste (RW) disposal facility (DGR) considering the scenario of the upcoming climate cooling. The evaluation is based on the analogy method with the comparison made against modern conditions explored at uranium deposits confined to the permafrost zone. The analogy is based on modern hydrogeological data from the Transbaikalia deposits explored using the underground borehole leaching method. This method yields no significant disturbance of the groundwater flow patterns. The study provides comparative analysis of climatic, geological and hydrogeological characteristics of the DGR siting area in the Krasnoyarsk Territory and those of uranium deposits in Transbaikalia. The limitations of this method have been validated. The paper highlights the main characteristics of groundwater flows in sub-permafrost aquifers. The results obtained may prove to be helpful in the development of models demonstrating radionuclide transport from the DGR developed at the Yeniseiskiy site.
