Michalski, G. Geomorphic process rates in the central Atacama Desert, Chile: Insights from cosmogenic nuclides and implications for the onset of hyperaridity. Evidence for multiple Plio-Pleistocene lake episodes in the hyperarid Atacama Desert. We note that discontinuous tectonic movement is not required to explain the timing of hydrological re-arrangement in our study area. Alpers, C. Springer,

Late Pleistocene human occupation of the hyperarid core in the Atacama Desert, northern Chile. Erosion of low-angle surfaces will result in the dispersal to younger ages, as the resulting lag-deposits contain material exhumed from various depths of shielding.

    Taking the cluster of youngest zircon ages as indication for the eruption ages, is based on the assumption that young zircons are unlikely to have experienced significant Pb loss, which would result in anomalously young ages It forms a steep scarp, partially modified by gravitational slumping Fig.
