The transgressive-regressive cycle of the Romualdo Formation (Araripe Basin): Sedimentary archive of the Early Cretaceous marine ingression in the interior of Northeast Brazil
(2017-08-15)
Geologic events related to the opening of the South Atlantic Ocean deeply influenced the sedimentary record of the Araripe Basin. As consequence, upper stratigraphic units of the basin record a marine ingression in ...
A cunha do ciclo de fácies do Grupo Guatá (Eopermiano) na margem sub-aflorante do norte paranaense
(Universidade Estadual Paulista (Unesp), 2012)
A wedge facies cycle it‟s a body of sedimentary rock, bounded above and below by unconformity and which represents a transgressive-regressive cycle of deposition. This cycle is formed by the following succession of facies: ...

Depositional processes and stratigraphic evolution of the Campanian deltaic system of La Anita Formation, Austral-Magallanes Basin, Patagonia, Argentina
(Asociación Argentina de Sedimentología, 2019-04)
Coastal depositional systems are commonly classified in terms of the relative interaction of wave, tide and fluvial processes. The La Anita Formation represents the opportunity to study and better understand coastal ...
Arquitetura estratigráfica da formação Romualdo, pós-rifte da Bacia do Araripe, Brasil
(Universidade Estadual Paulista (Unesp), 2017-04-07)
Os eventos geológicos relacionados à abertura do Oceano Atlântico Sul influenciaram profundamente o registro sedimentar da Bacia do Araripe. A Formação Romualdo, unidade superior do Andar Alagoas (neo-Aptiano a eo-Albiano), ...
Driving processes and recognition criteria for complex subaerial unconformities in a non‐marine succession: Implications for basin margin shaping during forced regressions
(Wiley Blackwell Publishing, Inc, 2020-02)
A regional sedimentological and sequence stratigraphic analysis is presented in this paper to provide new insights into the morphological complexity and sedimentary mechanisms of unconformities giving shape to basin margins. ...
Caracterización geológica del metamorfismo diastatermal mesozoico en la Cuenca Neuquina y su relación con la anomalía térmica en el sinriftGeological characterization of the Mesozoic diastathermal metamorphism of the Neuquina basin and its relationship with the thermal anomaly in the syn-rift
(Asociación Geológica Argentina, 2018-09)
Esta contribución trata el análisis mineralógico, textural y microestructural de rocas metamórficas de muy bajo grado del sinrift de la Cuenca Neuquina en los depocentros de Rahue-Chachil y Cordillera del Viento. Además, ...
