The role of dune morphogenetic history in the interpretation of linear dune luminescence chronologies : a review of linear dune dynamics

Auteur :
MUNYIKWA, K.

Description :
Contemporary knowledge on aeolian dune dynamics is reviewed to enable an appraisal of evolutionary mechanisms involved in linear dune stratigraphic sequence development. The degrees of depositional record retention in the dune structures are evaluated and the corollary applied to methods used in the interpretation of luminescence dating chronologies acquired from such sedimentary accumulations. It is demonstrated that morphogenetic aspects of dune development are an imperative element to invoke when carrying out palaeoenvironmental reconstruction using luminescence dating ages acquired from linear dune sequences.
