New palynological evidence from the Rincón Formation, Chacoparaná Basin, Argentina: implications for regional Devonian paleogeographic dynamics
Keywords:
Eifelian–Givetian, biostratigraphy, paleoenvironment, hydrocarbon exploration, South AmericaAbstract
The Chacoparaná Basin, has long been recognized for its hydrocarbon potential due to its extensive Paleozoic sedimentary deposits. This study reexamines the palynological assemblage of the Rincón Formation, recovered from the "El Rincón" exploration well (YPF.SE.ER.x-1) in Santiago del Estero Province, Argentina. By integrating taxonomic, biostratigraphic, and paleoecological analyses, we provide a refined age determination and paleoenvironmental reconstruction. The recovered assemblage comprises both marine and terrestrial palynomorphs, with a dominance of marine elements indicating a marginal marine depositional environment. Key identified species suggest an Eifelian to Givetian age. Hierarchical clustering and ordination analyses reveal regional and temporal affinities with other Devonian assemblages across Argentina, supporting the hypothesis of pronounced provincialism during the Early Devonian. This study highlights the importance of palynological analysis in refining stratigraphic correlations and enhancing our understanding of regional paleogeographical evolution, offering valuable insights for future hydrocarbon exploration in the area.
