Palynology of the jejenes formation (Carboniferous) in the Las Lajas Creek, San Juan Province, Argentina: New palaeoenvironmental inferences

The palynological systematic study of the Jejenes Formation (Upper Carboniferous), at Las Lajas Creek is presented. A diversified palynological assemblage including microspores, megaspores, pollen grains and acritarchs has been recognized. Twenty one samples were revised and 25 species are identifie...
