The project will also benefit from the methodological developments of the UraMod (CNRS programme NEEDS <a href=\"https:\/\/needs.in2p3.fr\/\">https:\/\/needs.in2p3.fr\/<\/a>) structuring project.<\/p>\n<p>The most recent work on Ba\/sulphide mineralisation in the basin shows that the main mobilisation of fluids and metals is associated with the Permian rifting phase and is concealed by the Middle Triassic. The Jurassic or Cretaceous ages obtained by U-Pb in the 1990s do not therefore appear to correspond to the main periods of emplacement of uranium mineralisation.<\/p>\n<p>This project aims to define the origin, conditions of mobilisation, transport, trapping and re-mobilisation of uranium in the Lod\u00e8ve Basin: in other words, to establish a coherent metallogenic model, which does not exist to date.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-175\" src=\"https:\/\/geops.geol.u-psud.fr\/br\/wp-content\/uploads\/sites\/2\/2025\/12\/Fig-projet-3-8-300x176.png\" alt=\"\" width=\"769\" height=\"451\" srcset=\"https:\/\/geops.geol.u-psud.fr\/br\/wp-content\/uploads\/sites\/2\/2025\/12\/Fig-projet-3-8-200x118.png 200w, https:\/\/geops.geol.u-psud.fr\/br\/wp-content\/uploads\/sites\/2\/2025\/12\/Fig-projet-3-8-300x176.png 300w, https:\/\/geops.geol.u-psud.fr\/br\/wp-content\/uploads\/sites\/2\/2025\/12\/Fig-projet-3-8-400x235.png 400w, https:\/\/geops.geol.u-psud.fr\/br\/wp-content\/uploads\/sites\/2\/2025\/12\/Fig-projet-3-8-600x353.png 600w, https:\/\/geops.geol.u-psud.fr\/br\/wp-content\/uploads\/sites\/2\/2025\/12\/Fig-projet-3-8-768x451.png 768w, https:\/\/geops.geol.u-psud.fr\/br\/wp-content\/uploads\/sites\/2\/2025\/12\/Fig-projet-3-8-800x470.png 800w, https:\/\/geops.geol.u-psud.fr\/br\/wp-content\/uploads\/sites\/2\/2025\/12\/Fig-projet-3-8-1024x602.png 1024w, https:\/\/geops.geol.u-psud.fr\/br\/wp-content\/uploads\/sites\/2\/2025\/12\/Fig-projet-3-8-1200x705.png 1200w, https:\/\/geops.geol.u-psud.fr\/br\/wp-content\/uploads\/sites\/2\/2025\/12\/Fig-projet-3-8-1536x903.png 1536w, https:\/\/geops.geol.u-psud.fr\/br\/wp-content\/uploads\/sites\/2\/2025\/12\/Fig-projet-3-8.png 1783w\" sizes=\"(max-width: 769px) 100vw, 769px\" \/><\/p>\n<p>Key words: Uranium, Lod\u00e8ve, resources, metallogeny, dating, fluid circulation, numerical modelling, NEEDS.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Project leader<\/strong>\u00a0: Antonio Benedicto<\/p>\n<p><strong>Funding\u00a0:<\/strong> CNRS programme NEEDS <a href=\"https:\/\/needs.in2p3.fr\/\">https:\/\/needs.in2p3.fr\/<\/a><\/p>\n<p><strong>Staff involved at GEOPS\u00a0: <\/strong>Antonio Benedicto, Paul Coutable (PhD student)<\/p>\n<p><strong>Collaboration with<\/strong><\/p>\n<p>G\u00e9osciences Rennes : Philippe Boulvais, Fr\u00e9d\u00e9rique Moureau, Yanick Branquet et Christian Le Carlier De Veslud<\/p>\n<p>G\u00e9osciences Montpellier\u00a0: Gregory Ballas, Michel Lopez<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Lod\u00e8ve Basin uranium system revisited: origin, conditions of mobilisation,  [&#8230;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[27],"tags":[],"class_list":["post-282","post","type-post","status-publish","format-standard","hentry","category-resource-geology"],"_links":{"self":[{"href":"https:\/\/geops.geol.u-psud.fr\/br\/wp-json\/wp\/v2\/posts\/282","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/geops.geol.u-psud.fr\/br\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/geops.geol.u-psud.fr\/br\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/geops.geol.u-psud.fr\/br\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/geops.geol.u-psud.fr\/br\/wp-json\/wp\/v2\/comments?post=282"}],"version-history":[{"count":1,"href":"https:\/\/geops.geol.u-psud.fr\/br\/wp-json\/wp\/v2\/posts\/282\/revisions"}],"predecessor-version":[{"id":283,"href":"https:\/\/geops.geol.u-psud.fr\/br\/wp-json\/wp\/v2\/posts\/282\/revisions\/283"}],"wp:attachment":[{"href":"https:\/\/geops.geol.u-psud.fr\/br\/wp-json\/wp\/v2\/media?parent=282"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/geops.geol.u-psud.fr\/br\/wp-json\/wp\/v2\/categories?post=282"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/geops.geol.u-psud.fr\/br\/wp-json\/wp\/v2\/tags?post=282"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
