The hyperarid core of the Atacama Desert possesses important reserves of “fossil” or ancient
groundwater, yet the extent and timing of past hydrologic change during the late Quaternary …

Abstract The Atacama Desert contains the driest regions on Earth, with significant rain
occurring only a few times per century, based on sparse historical records. However, the …

The Atacama Desert in Chile—hyperarid and with high–ultraviolet irradiance levels—is one
of the harshest environments on Earth. Yet, dozens of species grow there, including …

Study of human adaptation to extreme environments is important for understanding our
cultural and genetic capacity for survival. The Pucuncho Basin in the southern Peruvian …

The sedimentary succession in the Atacama Desert records deposition under an arid to
semiarid climate from the late Jurassic (150 Ma) to the present day. Palaeomagnetic data …

The Atacama Desert of northern Chile and southern Peru has one of the longest histories of
arid conditions known. Although most studies have focused on the hyper-aridity prevalent …

Widespread evidence for human occupation of the Atacama Desert, 20° to 25° S in northern
Chile, has been found from 13,000 calibrated 14C years before the present (cal yr BP) to …

The soils of the Atacama Desert in northern Chile have long been known to contain large
quantities of unusual salts, yet the processes that form these soils are not yet fully …

Supergene leaching, oxidation, and chalcocite enrichment in porphyry and related Cu
deposits take place in the weathering environment to depths of several hundred meters. The …

Widespread, organic-rich diatomaceous deposits are evidence for formerly wetter times
along the margins of the central Atacama Desert, one of the driest places on Earth today. We …
