Unconformity-associated uranium deposits typically consist of uranium concentrations at the unconformable base of Proterozoic sandstone where it is in contact with Middle Proterozoic metamorphic basement rocks ... Step faults or fracture zones are associated features. ... The unconformity-associated deposits are, in general, hosted by Proterozoic rocks. Their mineralization is epigenetic and formed, as a rule, during several periods.  4, fiche 1, Anglais, - unconformity%2Dassociated%20deposit

Uranium. ... commercial grade concentrations occur mainly in rocks of pre-1,000 m.y. and post-230 m.y. age with rather limited resources between these ages. The older group includes several types of deposits including the conglomerate deposits of the Witwatersrand, South Africa and Elliot Lake, Canada ... and deposits associated with unconformities dating between 1,700 and 1,200 m.y.  5, fiche 1, Anglais, - unconformity%2Dassociated%20deposit

... unconformity uranium deposits have some features in common with redbed-type copper deposits, but they were probably formed at different times, in different areas and from different ore fluids.  4, fiche 1, Anglais, - unconformity%2Dassociated%20deposit

Unconformity-associated uranium deposits typically consist of uranium concentrations at the base of a Proterozoic sandstone sequence where it unconformably overlies pre-Middle Proterozoic metamorphic basement rocks, which commonly include graphitic pelitic units. The deposits are associated with fault or fracture zones.  1, fiche 2, Anglais, - unconformity%2Dassociated%20uranium%20deposit

Les gîtes d’uranium associés à des discordances consistent typiquement en concentrations d’uranium présentes à la base d’une séquence de grès d’âge protérozoïque, là où cette séquence repose en discordance sur un socle composé de roches métamorphiques antérieures au Protérozoïque moyen parmi lesquelles on retrouve souvent des unités pélitiques graphitiques. Les gîtes sont associés à des zones de failles ou de fracture.  1, fiche 2, Français, - g%C3%AEte%20d%26rsquo%3Buranium%20associ%C3%A9%20%C3%A0%20des%20discordances
