Tectonic vs. climate controls on the evolution of a miocene intermontane basin, Patagonian Andean foreland, Argentina

چکیده
The interaction of tectonics and climate is considered the main determining factor in development different depositional systems (from aeolian to alluvial lacustrine environments) intermontane basins. role these allogenic controls forces paleoenvironmental evolution In this work, we analyse a Miocene (15–11.5 Ma) synorogenic volcaniclastic succession an basin Northpatagonian Andean foreland region. infill was synchronously developed with uplift and, consequently, rain shadow effect generation. A detailed sedimentological stratigraphic analysis allowed define eight facies associations, which are lateral vertical stacked into three systems. Alluvial occurred between 15 14.6 Ma, deltaic–lacustrine took place 12.75 reinstatement 11.5 Ma. These variations were contrasted synchronous tectonic climatic changes some considerations about discussed unravel their influence on evolution. onset system related reconfiguration whereas associated regional aridization. Additionally, since composition mainly volcaniclastic, explosive volcanism as extra control basin.

[1] Previous quantitative studies dealing with the origin of foreland basins have focused primarily either on the rheological basis of the lithosphere mechanical response or on the relationship between orogenic loading and sediment geometry. To link the evolution of the Guadalquivir foreland basin (South Iberia) with the thermomechanical stratification of the Iberian lithosphere, we combine qua...
متن کاملForeland basin stratigraphic control on thrust belt evolution
The link between orogenic activity and foreland basin stratigraphy is well established; however, potential controls by foreland basin stratigraphy on thrust belt architecture have not been fully evaluated. Mechanical properties of typical foreland basin stratigraphic successions influence the structural development of fold-thrust belts in predictable ways. Fundamental features of foreland basin...
