• New models of sedimentary basins and depth to the Moho of South America were developed to improve lithospheric modeling • Deep depleted roots under the Amazon, Paranapanema and São Francisco cratons are evident from models of lithospheric temperatures, densities and composition • Depletion south of the Paranapanema Craton indicates a previously larger extent of the craton Accepted Article This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record.

“…The Pavas Block is a small (i.e., 3000 km 2 ), elongated Archean/Paleoproterozoic inlier located in the centre of the Nico Pérez Terrane of central Uruguay (Preciozzi et al, 1979(Preciozzi et al, , 1985Masquelin, 2006;Sánchez Bettucci et al, 2010;Oriolo et al, 2016a;Oyhantçabal et al, 2018;Fig. 1).…”

“…The magnetotelluric profile indicates that the Pavas and Cerro Chato blocks both have a 200 kilometre's thickness, which is inherited from a cratonic setting (Bologna et al, 2019). In geological maps, the block's shape seems controversial, depending on how different authors interpreted their boundary faults (e.g., Preciozzi et al, 1979;Sánchez Bettucci et al, 2010;Oyhantçabal et al, 2021). Some sketches place an eastward convexity for the western limit, called the Cueva del Tigre Fault (Preciozzi et al, 1979).…”

In this chapter, based on the available geological information, a model for the genesis and evolution of the Uruguayan landscape is proposed. A structural framework of the landscape evolution is provided and the record of such evolution in the most representative geological units is considered. A brief summary of the Uruguayan geology and its location in the regional context is performed, from Precambrian to Cenozoic times.From the analysis of the geological record, it may be observed that the climate was very arid during part of the Jurassic and the Early Cretaceous. Together with the lava flows of the Arapey Formation, the climate became less arid as the Gondwana continents were becoming apart from each other. However, the geological record suggests that semiarid climates were still prevailing. In the Middle Cretaceous, semiarid and wetter climates progressively alternated, until the Early Tertiary, when very wet and warm conditions were established, in coincidence with the "Palaeocene-Eocene Thermal Maximum (PETM)", followed by semiarid climates in the Oligocene, wetter conditions in the Miocene and semiarid again in the Pliocene, with alternating semiarid and humid conditions during the entire Quaternary.
