A preliminary lithostratigraphy for the Upper Quaternary deposits of the Middle-Lower valley of the Paraíba do Sul river here tried, based on the systematic reproduction of some exposed sections. An special attention given to the slope materials, since the colluvial deposits are considered to be highly significative within the moist tropical environments. Three different colluvial sequences are heve identified: a) lower sequence, of Pleistocene age, is characterized by the occurrance of reddish, ...

From west to east, three contemporaneous regressive zones can be recognized: the Paracatu Zone, with basal black schists, phyllites of the Western Facies and turbidites of the Eastern Facies; the Vazante Zone, a dolomitic barrier reef complex; and the State Zone on the continental platform, which contains patch reefs of the Lagamar Facies. These ...

The Camaqua Group is composed of sedimentary and volcanogenic successions that crop out in the south-central portion of the Rio Grande do Sul State (southern Brazil). This supergroup is partially covered by Parana Basin units and has been divided into sub-basins by the uplift of basement highs. This post-depositional tectonic segmentation, and the lithologic similarity among sedimentary successions of different stratigraphic levels makes it difficult to establish a formal lithostratigraphic column ...

This paper deals with new data on the lithostratigraphy of the Upper Paleocene-Lower Oligocene successions in the Pontils-Montblanc area (western part of the southeastern margin of the Eastern Ebro Basin, NE Spain). The new contributions point to the fact that the Bartonian-Priabonian marine and transitional facies of the Sta. Maria Group extend to the southwest as far as Barbera de la Conca. This fact together with the mapping of the recorded major progressive and angular syntectonic unconformities ...

The mesozoic acidic volcanic rocks of Parana Basin: lithostratigraphy and geochemical stratigraphy aspects. The mesozoic acidic volcanics of Parana Basin covers an area of 64,000 km 2 or 2.5% of the total volume of Serra Geral Formation. Two main types are recognized and are named Palmas (aphyric rocks) and Chapeco (porphyritic rocks). The Palmas type (2% of total volume) dominate over the Chapeco (0.5% vol.) one. In the Parana State, it is possible to found the Chapeco overlaying the Palmas volcanic ...

The Andrelândia Nappe System represents a crustal segment subducted under the Paranapanema Plate (Socorro-Guaxupé Nappe), which is allochthonous over the passive margin of the Sanfranciscan Plate (the Carrancas Thrust System). Three large structures transported to the E-NE and coeval to high-pressure metamorphism at ca. 610 Ma make up the eastern sector of this nappe system. The upper Pouso Alto Nappe and associated klippen is composed of pelitic granulites, while the Liberdade Nappe is dominantly ...

The stratigraphie framework of the non-marine Upper Eocene-Lower Oligocene in the Eastern Ebro Basin (Igualada-Sta. Coloma de Queralt area) is characterized by three main lithostratigraphic assemblages. The lower assemblage (Upper Eocene) comprises units mainly formed by alluvial deposits. The intermediate assemblage (Lowermost Oligocene) is formed by units wich originated in lacustrine environments. The upper assemblage (Lower Oligocene) comprises units formed by lacustrine and fluviolacustrine deposits. ...

From new biostratigraphic and lithostratigraphic data, a revision is made of the Paleogene of the Malaguide Complex of Sierra Espuna, located in the Interna1 Zone (Internal-Externa1 Zone Boundary) of the Betic Cordillera. The Paleogene deposits are characterized according to formations and integrated into depositional sequences and sedimentary cycles. The biostratigraphic data are based on larger forarninifers, planktonic foraminifers, and calcareous nannoplankton. The results are integrated into ...
