RT Journal Article T1 Reinterpretación paleoambiental de la Formación Rio Bonito (Pérmico de la Cuenca de Paraná) en el yacimiento de carbón de Iruí, Rio Grande do Sul, Brasil: Integración de análisis de facies, ¡enología y estratigrafía secuencial de alta resolución T1 Paleoenvironmental reinterpretation of the Rio Bonito Formation (Permian, Paraná Basin) in the Iruí Coal Mine, Rio Grande do Sul, Brazil: Integration of facies analysis, ichnology and high-resolution sequence stratigraphy A1 Buatois, L. A. A1 Netto, F. G. A1 Mángano, M. G. AB The Permian Rio Bonito Formation of the Parana Basin, southern Brazil, has been traditionally interpreted in terms of a fluvio-dominated deltaic model. Integration of facies analysis, ichnology, and high-resolution sequence stratigraphy suggests that this unit represents deposition in a tide-dominated, fluvio-estuarine valley system.
