| 1 | Uranium,rare metals,and granulite-facies metamorphism显示文摘During granulite-facies metamorphism of metasedimentary rocks by the infiltration of carbonic fluids.the disappearance of hydrated minerals leads to the liberation of aqueous fluids.These fluids arc strongly enriched in Fand CI,and a series of Large-lon-Lithophile(LIL) elements and rare metals.resulting in their depletion in granulites.To sum up the fate of these elements,we focus on three domains representing different crustal levels and showing distinct behaviours with respect to these elements.The Lapland metasedimentary granulites illustrate the behaviour of the LI1.E and rare metals during lower crustal metamorphism.There is no change in Ba.moderate loss in Kb,and extreme depletion in Cs,Li,and Sn.F and CI contents are also very low compared to the protoliths or average upper continental crust.Biotite and amphibole breakdown leads to the incorporation of their partitioning into a fluid or a melt.The Tranomaro metasomatized marbles recrystallizing under granulite-facies conditions represent a demonstrative example of fluid transfer from granulite-facies supiacrustals to traps represented by regional scale skarns.Such fluids may be at the origin of the incompatible element enrichment detected in leucosomes of migmatites from St Malo in Brittany(France) and Black Hills in South Dakota.The northern French Massif Centra]provides us with an example of a potential association between incompatible element enrichment of granitic melts and granulite-facies metamorphism.U- and Fenriched fine-grained granites are emplaced along a crustal scale shear zone active during the emplacement within the St Sylvestre peraluminous leucogranitic complex.We propose that during granulite-facies metamorphism dominated by carbonic waves in a deep segment of the continental crust,these shear zones control:(i) the percolation of F-,LILE-,rare metal-rich fluids liberated primarily by the breakdown of biotite;(ii) the enhancement of partial melting by F-rich fluids at intermediate crustal levels with the generation of F-,LILE-,rare metal-rich granitic melts;(iii) their transfer through the crust with protracted fractionation facilitated by their low viscosity due to high F-Li contents;and finally(iv)their emplacement as rare metal intrusions at shallow crust levels. | Michel Cuney Pierre Barbey | 2014 | Geoscience Frontiers2014，5，5： | 6 |

| 12 | Classification of Sandstone-Related Uranium Deposits显示文摘Sandstone type deposits are the most common type of uranium deposits in the world.A large variety of sub-types have been defined,based either on the morphology of the deposits(e.g.,tabular,roll front,etc),or on the sedimentological setting(e.g.,paleovalley,paleochannel,unconformity),or on tectonic or lithologic controls(e.g.,tectonolithologic,mafic dykes/sills),or still on a variety of others characteristics(phreatic oxidation type,interlayer permeable type,multi-element stratabound infiltrational,solution front limb deposit,humate type,etc.),reflecting the diversity of the characteristics of these deposits,but making it difficult to have a clear overview of these deposits.Moreover,uranium deposits occurring in the same sedimentological setting(e.g.,paleochannel),presenting similar morphologies(e.g.,tabular),may result from different genetic mechanisms and thus can be misleading for exploration strategies.The aim of the present paper is to propose a new view on sandstone-related uranium deposits combining both genetic and descriptive criteria.The dual view is indeed of primordial importance because all the critical characteristics of each deposit type,not limited to the morphology/geometry of the ore bodies and their relationships with depositional environments of the sandstone,have to be taken into account to propose a comprehensive classification of uranium deposits.In this respect,several key ore-forming processes,like the physical-chemical characteristics of the mineralizing fluid,have to be used to integrate genetic aspects in the classification.Although a succession of concentration steps,potentially temporally-disconnected,are involved in the genesis of some uranium mineralization,the classification here proposed will focus on the main mechanisms responsible for the formation and/or the location of ore deposits.The objective of this paper is also to propose a robust and widely usable terminology to define and categorize sandstone uranium deposits,considering the diversity of their origin and morphologies,and will be primarily based on the temperature of the mineralizing fluid considered as having played the critical role in the transportation of the uranium,starting from synsedimentary uranium deposits to those related to higher temperature fluids. | Michel Cuney Julien Mercadier Christophe Bonnetti | 2022 | Journal of Earth Science2022，33，2： | 1 |
