Perennial stream discharge in the hyperarid Atacama Desert of northern Chile during the latest Pleistocene.
A large fraction of the vital groundwater in the Atacama Desert of northern Chile is likely composed of "fossil" or "ancient" reserves that receive little or no recharge in today's hyperarid climate. Here, we present evidence for latest Pleistocene perennial streamflow in canyons from the hyperarid core of the Atacama Desert in northern Chile. Fluvial terraces in the Pampa del Tamarugal (PdT) b...
متن کاملEmergence of social complexity among coastal hunter-gatherers in the Atacama Desert of northern Chile.
The emergence of complex cultural practices in simple hunter-gatherer groups poses interesting questions on what drives social complexity and what causes the emergence and disappearance of cultural innovations. Here we analyze the conditions that underlie the emergence of artificial mummification in the Chinchorro culture in the coastal Atacama Desert in northern Chile and southern Peru. We pro...
متن کاملActive erosion–deposition cycles in the hyperarid Atacama Desert of Northern Chile
There is significant debate over the rates and types of fluvial activity at the Plio-Pleistocene boundary in the hyperarid Atacama Desert of Chile. To quantify fluvial processes and help resolve this debate, we measure terrestrial cosmogenic nuclide (TCN) (Be and Ne) concentration depth profiles in three settings representing a chronosequence: (1) a late Pliocene alluvial fan representative of ...

متن کاملA new freshwater snail (Caenogastropoda: Cochliopidae) from the Atacama Desert, northern Chile.
In the family Cochliopidae, Heleobia Stimpson, 1865 is the most speciose genus in South America, with about 90 species (Hershler & Thompson 1992; Cazzaniga 2011). A recent molecular and morphological analysis performed in northern Chile (Atacama Desert) showed that the previously undescribed springsnails from Aguada de Chorrillos belong to Heleobia (Collado et al. 2013). In this study I formall...
