Sedimentary facies and palynofacies assemblages in an Eocene perennial lake, Lumbrera formation, northwest Argentina
(Pergamon-Elsevier Science Ltd, 2002-10)
The combined application of sedimentary facies and palynofacies analyses constitutes a valuable method for paleoenvironmental andpaleoclimatic reconstructions, especially in continental strata in which fossil information ...
