Although Earth's climate history is best known through marine records, the corresponding continental climatic conditions drive evolution of terrestrial life. Continental during latest Miocene are particular interest because global faunal turnover roughly synchronous with a period glaciation from ∼6.2-5.5 Ma and Messinian Salinity Crisis ∼6.0-5.3 Ma. Despite ecological significance this period, associated it remain unclear. We address question using erosion rates ancient watersheds to...
Drought episodes during the early–mid 20th century were recognized and described in several places around world, with extreme dry conditions widespread landscape denudation, like famous ‘Dust Bowl’ North America. However, there is scant documentation of droughts southern South America, particularly from Pampas, none based on geological record. In this article, we provide clear evidence aeolian reactivation sand deposition some areas La Pampa San Luis provinces, western Pampas (Argentina),...
Paganzo Group exposures (Tupe Formation) in the Huaco area provide an excellent opportunity for assessing role of sea level and climatic changes on morphology nature coastal fluvial systems deposited areas limited tectonic activity. The paleogeographic position Huaco, close to a region within Basin, allows identification effects change architecture. Despite fact that was dominated by systems, three marine incursions flooded this part basin during Namurian, Early Pennsylvanian Late...
The Miocene Vinchina Formation is made up of more than 5100 meters siliciclastic sediments deposited mostly in fluvial environments a broken foreland basin without any connection with the sea during period arid to semiarid climatic conditions.Repetitive changes facies allow subdivision formation into seven cyclothems, each floored by subaerial unconformity.Within-sequence systems determined proportion channel vs floodplain, multi-story single-story channels, and connectedness were controlled...

The Toro Negro Formation (Neogene) records the sedimentation in broken-foreland Vinchina Basin during Andean Orogeny, northwestern Argentina. This unit is composed of conglomerates, sandstones and mudstones together with some beds breccias tuffs deposited mainly fluvial environments. Eleven facies associations (FA) were identified this unit, eight them corresponding to lower member three upper member. FAI massive intraformational megabreccias cross-bedded conglomerates braided systems that...
ABSTRACT Two episodes of lacustrine sedimentation, separated by an erosional surface and fluvial took place in the southern part broken foreland Vinchina basin (NW Argentina) between 11 5 Ma. The deposits, 768 740 meters thick, are recorded upper Formation (“Vinchina lake”) lower Toro (“Toro Negro respectively. According to sedimentological features, four sedimentary facies associations (FAs) recognized deposits: 1) thinly laminated mudstones association (FA 1), 2) coarsening-...
