RT Journal Article T1 Revisión de la estratigrafía del Grupo Tremp («Garumniense», Cuenca de Tremp-Graus, Pirineos meridionales) T1 The stratigraphy of the Tremp Group revisited («Garumnian», Tremp-Graus basin, South Pyrenees) A1 Pujalte, Victoriano A1 Schmitz, Birger AB The term Tremp Group reflects more appropriately than the former Tremp Formation the stratigraphiccomplexity of the so-called «Garumnian» of the south Pyrenean Tremp-Graus basin. However, the currentdefinitions of some of the formal units making up the Tremp Group are somewhat inconsistent. New fieldobservations and, mainly, the discovery of the carbon isotopic excursion of the Initial Eocene ThermalMaximum, permit to correlate key sections of the Tremp Group with far more reliability than was hithertopossible. On the light of that correlation we revise the original definitions of the Talarn, Esplugafreda andClaret Formations, and of some of its members, and propose modifications to clarify their boundaries andages PB Sociedad Geológica de España YR 2005 FD 2005 LK http://hdl.handle.net/10272/8757 UL http://hdl.handle.net/10272/8757 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
