Powell et al., 2011: Recently, geologic and paleontologic evidence allowed the correlation of the upper levels of Lumbrera with Geste, Casa Grande, and Quebrada de los Colorados Formations. Additionally, these levels were referred to the late-middle Eocene (Casamayoran SALMA -South American Land Mammal Age-, Barrancan subage) by an U/Pb dating of 39.9 Ma . The lower levels of the Lumbrera Formation are here referred to the Vacan subage of the Casamayoran SALMA.
Fernicola et al. 2021: new 238U-206Pb isochron age (46.2 Ma) obtained from samples taken on various independent points across paleosol and matrix positioned at the top of the lower section of the Lumbrera Formation. The new age is consistent with the hyperthermal scheme and constrains the deposition of the lower section of the Lumbrera Fm. between 55–46.2 Ma. Subsequently, the upper sections of the Lumbrera Formation are now constrained between 46 and 40 Ma (Lutetian) (see Fernicola et al. 2021: New assemblage of cingulates)
Lithology and environment
Primary lithology:peloidal,red mudstone
Secondary lithology:"cross stratification",red sandstone
Includes fossils?Y
Lithology description: translated: Lumbrera Formation is characterized predominantly by red mudstones. It is approximately 410 m with 50 m of red, medium-grained, cross-stratified sandstone at the base. On top, it has the characteristics of brick-red pelites, which are finely to massively bedded, very fragmented, and fossil-bearing. Above the pelite is a calcareous sandstone with green and brown pelitic intercalations, above which is a fossil-bearing layer of red pelite.
Environment:terrestrial indet.
