Origin of the pegmatites and associated uranium mineralization from the CAGE province (North Québec)
J. Bonhoure ; F. Castorina ; M. Cuney ; Réunion des Sciences de la Terre (2014-10-27 / 2014-10-31; Pau, France) | 2014-10-27 00:00:00,000In the western part of the Torngat Mountains (north Quebec), uranium mineralizations are observed in metasediments, mainly localized in the Lake Harbour group. This group consists of calcitic and dolomitic marbles, paragneisses, quartzites, calc[...]![]()

Richard ; Goldschmidt Conference (2012-06-24 / 2012-06-29; Montreal, Canada) | 2012-08-01 00:00:00,000Uranium deposits have formed in a wide range of geological settings including deep metamorphic/magmatic to surficial conditions and range in age from Archean to recent time. These temporal and spatial variations have given rise to an extreme div[...]![]()

J. Bonhoure ; O. Pourret ; Goldschmidt Conference (2011-08-14 / 2011-08-19; Prague, Czech Republic) | 2011-08-22 00:00:00,000To better understand the formation of uranium deposits, rare earth elements (REE) and particularly REE compositon of oxides is a powerful tool. Indeed, REE fractionation occurs in uranium oxide [1] by substitution with U and REEs are poorly affe[...]![]()

D. Roudil ; J. Bonhoure ; R. Pik ; M. Cuney ; C. Jégou ; F. Gauthier-Lafaye |The issue of nuclear waste management – and especially spent fuel disposal – demands further research on the long-term behavior of helium and its impact on physical changes in UO2 and (U,Pu)O2 matrices subjected to self-irradiation. Helium produ[...]![]()

Deloule ; International Symposium Uranium (2005-06-20 / 2005-06-24; Vienna, Austria) | 2005-06-24 00:00:00,000Natural uranium oxides (UO 2+x ) can incorporate variable quantities of other elements during their crystallization. The processes of incorporation depend on (i) the element ionic radius, (ii) the physical-chemical characteristics of the miner[...]![]()
