“…Crustal thickening, surface uplift and exhumation of the central Andes commenced in the Eocene (McQuarrie et al 2005(McQuarrie et al , 2008Ege et al 2007), and the Altiplano plateau had its modern width at 20 Ma at the latest (Barnes et al 2006). Exhumation rates in the Eastern Cordillera accelerated between 15 and 11 Ma (Gillis et al 2006) when folding of the Bolivian Subandes ( Fig.…”

We focus on the sedimentological record of the Middle Miocene to modern deposits in the Andes of northern Chile between 19 and 21°S. These sediments, deposited at the Western Escarpment of the Central Depression, indicate successively more moisture on the western margin of the Altiplano and the Western Cordillera where the sources are. At the Pacific Coast, 20-Ma-old exposure ages and salic gypsisols reflect an existing and ongoing hyperarid climate. We interpret the increased divergence of climates between the Coast and the Altiplano as consequence of the Andean rise to elevations higher than approximately 2,500 m a.s.l., when the topography of the Altiplano was sufficiently high and areally extensive to attract Atlantic moisture. Accordingly, the inferred general increase in run-off was closely coupled with the uplift of the Andes if the steady rise model applies. In case that the rapid rise model for Andean uplift is correct, the inferred changes in sediment transport would have occurred independently of uplift, requiring an alternative, yet unknown driver.

“…Topographic isolation of the Altiplano basin has been linked to a major cratonward advance of the thrust front (McQuarrie, 2002a;DeCelles and Horton, 2003;McQuarrie et al, 2005). Uplift and erosion of the western arc and eastern thrust belt are expressed in the provenance record of the Altiplano (Horton et al, 2002a) and low-temperature thermochronology of plateau margins (Barnes et al, 2006;Gillis et al, 2006;Ege et al, 2007). (3) The only well-developed extensional basin in the Andean hinterland is located adjacent to the Cordillera Blanca ( Fig.…”

Tectonics of Sedimentary Basins

Sedimentary basins have been generated in hinterland regions of the Andean and Himalayan-Tibetan orogens during Cenozoic plate convergence. These hinterland basins record nonmarine sediment accumulation (commonly in high-elevation, lowrelief, internally drained, arid/semiarid settings) during protracted deformation and surface uplift of continental crust. In South America, Andean hinterland basins are produced between the western magmatic arc and craton-directed fold-thrust belt to the east. In the India-Asia collision zone, hinterland basins develop as elements of the growing Tibetan plateau between the Himalayan thrust belt and Asian plate interior to the north. Hinterland sedimentary basins in the Andes and Tibet are distinguished from foreland basins adjacent to their respective fold-thrust belts by structural position, elevation, and stratigraphic evolution. Sediment accommodation in these hinterland basins is created by flexure, fault-induced subsidence, and topographic ponding, with common examples of remnant foreland basins succeeded by younger hinterland basins.

“…Masek et al (1994) and Anders et al (2002) pointed out that the data from Benjamin et al (1987) show increased denudation rates around 10-15 Ma. More recently the AFT data from Barnes et al (2006) . It is worth noting that prior to the Late Miocene there is abundant evidence for deformation, but no evidence for high palaeoelevations along the Central and Northern Andes (see Fig.…”
