Triassic age of the continental Pular Formation, Sierra de Almeida, Antofagasta, northern Chile
In this contribution, we present a reassessment of the Pular Formation age (Sierra de Almelda, Antofagasta) that in previous papers was attributed to either the Late Paleozoic or Triassic. At Quebrada del Medio, the Pular Formation includes a 379-meter-thick stratigraphic section formed from base to...
