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...

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 identified. The paleoenvironmental interpretation of the sequence is based on acritarch-leiosphere-to-spore ratios. These indicate a nearshore marine environment for the basal and middle parts of the sequence; the interpretation is reinforced by dominantly woody organic matter in some samples. This paleoenvironmental evidence confirms the existence of the early Late Carboniferous postglacial transgression in the area. |
