...-core transects. Our data constrain the incision history of the Quebrada de Parca canyon in northern Chile from ca. 16 Ma to the present day. The erosional and topographic response of the Quebrada de Parca river suggests that incision was induced by a switch to a more arid climate in the middle Miocene...

Continued uplift incised numerous west-southwest–trending valleys, e.g., Quebrada Parca, shown by dashed line, which expose the volcanic rocks underlying the pampa gravel (after Thomas, 1967 ; Galli, 1968 ; Servicio Nacional de

The lower part of the sequence is composed of volcanic breccia (1), overlain by fine-grained porphyritic andesite (2), and dacitic lapilli tuff (3). These are covered
