 1. The Stratigraphy of the Argentinian Fuagean Andes Reveals Contrasting Mesozoic Cenozoic Tectonic Regimes 2. The La Mer Formation, Submarine Complex of Bimodal Volcanites, Brechas, and Sedimentary Rocks, the Yoggan Formation, Volcanoclastic Apron of Deep Marine and Acite-Rich Turbidites and Mudstones, and the Beauvoir Formation, Slope Mudstones, all evidence late Jurassic Early Cretaceous Extension and Consequent Origination of the Rocus Verde's Marginal Basin 3. The basal late Cretaceous Ductal Deformation, Isoclinal Folding, and Metamorphism of these rocks indicate a compressional tectonic regime that resulted in the closure of the Marginal Basin 4. The Fuagean Andes were uplifted by the late Campanian, subsequent propagation of the compressional deformation and subsidence by tectonic loading along the Northern Origenic Margin originated the Austral and Malvinus Forland Basins 5. The Turonian Lower Campanian Astratus Debune Suceso represents the final stages of the closure of the Marginal Basin and or the beginning of the Forland Basins 6. During the late Campanian to Mid-Myocene, the Foram Maniferal Assemblages This article was authored by E. B. Olivero and N. Malumon We are article.tv, links in the description below
