Antiquity of aridity in the Chilean Atacama Desert

Auteur :
CLARKE, J.D.A.

Description :
This paper provides a brief outline of the geomorphology and regolith architecture of the Atacama Desert and then examines the climatic conditions implicit in the depositional environments of onshore and marginal marine sediments from the Late Triassic to the present, based mainly on a review and reinterpretation of the literature published so far. It closes with a brief discussion on the significance of Quaternary climate fluctuations on the overall aridity of the region, and possible implications for the genesis of supergene mineralisation.
