Sergipe-Alagoas Basin
The Sergipe-Alagoas Basin is a continental margin basin in the Sergipe and Alagoas states of northeastern Brazil, about 20 to 50 kilometres wide onshore, but with its widest extension offshore, more precisely 13,000 km2 onshore and 40,000 km2 offshore. In general, "Sergipe-Alagoas Basin" refers to the Sergipe and Alagoas sub-basins, but it also consists of the Jacuípe and Cabo sub-basins. Studies of the basin's geology date back to the first half of the 19th century, when J. Henderson in 1821 published preliminary notes on the region's geology. The basin formed during the opening of the South Atlantic Ocean in the Late Jurassic and Cretaceous periods alongside other basins in the Brazilian coast. History Studies of the basin's geology date back to the first half of the 19th century, when J. Henderson in 1821 published preliminary notes on the region's geology, but the first geological and paleontological surveys were carried out in 1865–1866 by the Canadian natural ...

Sergipe
Sergipe (), officially State of Sergipe, is a state of Brazil. Located in the Northeast Region along the Atlantic coast of the country, Sergipe is the smallest state in Brazil by geographical area at , larger only than the Federal District. Sergipe borders Bahia to the south and west and Alagoas to the north. Aracaju is the capital and the largest city in the state; the state is divided into 75 municipalities. The state has 1.1% of the Brazilian population and produces only 0.6% of the Brazilian GDP. Geography As with most of the states in northeastern Brazil, inland Sergipe is almost entirely savanna (''caatinga''), and its coastline is characterized by mangroves, swamps and sandy beaches. A small strip of tropical rainforest runs down the coast. The São Francisco River forms its northern boundary, and the drainage of the northern part of the state is northward and eastward to that river. The southern half of the state slopes eastward and is drained directly into the Atlanti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laranjeiras, Sergipe
Laranjeiras (''English'': Orange trees) is a municipality located in the Brazilian state of Sergipe. Its population was 30,080 (2020) and covers . Laranjeiras has a population density of 180 inhabitants per square kilometer. Laranjeiras is located from the state capital of Sergipe, Aracaju. It borders the municipalities of Riachuelo, Areia Branca, Nossa Senhora do Socorro, São Cristóvão, Maruim, and Santo Amaro das Brotas, all within the state of Sergipe. The municipality contains part of the Serra de Itabaiana National Park. History Cristóvão de Barros killed or expelled the indigenous population of the Laranjeiras area around 1530. The Portuguese soon settled on the Cotinguiba River and built a small port, called the Porto de Laranjeiras, after numerous orange trees near the port. The port became a center of the slave trade in Sergipe as a result of its access to the interior and the Atlantic Ocean. The region was intensively attacked by the Dutch from 1637; they on ...

Syneclise
Sedimentary basins are region-scale depressions of the Earth's crust where subsidence has occurred and a thick sequence of sediments have accumulated to form a large three-dimensional body of sedimentary rock. They form when long-term subsidence creates a regional depression that provides Accommodation (geology), accommodation space for accumulation of sediments. Over millions or tens or hundreds of millions of years the deposition of sediment, primarily gravity-driven transportation of water-borne eroded material, acts to fill the depression. As the sediments are buried, they are subject to increasing pressure and begin the processes of compaction (geology), compaction and lithification that transform them into sedimentary rock. Sedimentary basins are created by deformation of Earth's lithosphere in diverse geological settings, usually as a result of plate tectonics, plate tectonic activity. Mechanisms of crustal deformation that lead to subsidence and sedimentary basin formati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riachuelo Formation
The Riachuelo Formation is a geologic Formation (stratigraphy), formation of the Early Cretaceous, Early to Late Cretaceous (Aptian, Late Aptian to Cenomanian) age in northeastern Brazil's Sergipe-Alagoas Basin. It is the first Formation of the Basin to contain sediments deposited under fully marine conditions. The formation is subdivided into three members: Angico, Taquari and Maruim. The formation has provided fossils of Ammonoidea, ammonites, Gastropoda, gastropods, Bivalvia, bivalves, brachiopods, Serpulidae, serpulids, Echinoderm, equinoderms, Ostracod, ostracoids, radiolarians, lobsters and Crabs. Several fish species reported from the Santana formation, Santana Formation also occur in this formation, namely: Cladocyclus, ''Cladocyclus gardneri'', Neoproscinetes, ''Neoproscinetes penalvai'', Notelops, ''Notelops brama'', Rhacolepis, ''Rhacolepis buccalis'', Tharrhias, ''Tharrhias araripis'' and Vinctifer, ''Vinctifer comptoni''.

Albian
The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/Series. Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan '' Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined as the place where the foram species '' Rotalipora globotruncanoides'' first appears in the stratigraphic column. The Albia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aptian
The Aptian is an age in the geologic timescale or a stage in the stratigraphic column. It is a subdivision of the Early or Lower Cretaceous Epoch or Series and encompasses the time from 121.4 ± 1.0 Ma to 113.0 ± 1.0 Ma (million years ago), approximately. The Aptian succeeds the Barremian and precedes the Albian, all part of the Lower/Early Cretaceous. The Aptian partly overlaps the upper part of the Western European Urgonian Stage. The Selli Event, also known as OAE1a, was one of two oceanic anoxic events in the Cretaceous Period, which occurred around 120 Ma and lasted approximately 1 to 1.3 million years. The Aptian extinction was a minor extinction event hypothesized to have occurred around 116 to 117 Ma.Archangelsky, Sergio.The Ticó Flora (Patagonia) and the Aptian Extinction Event" ''Acta Paleobotanica'' 41(2), 2001, pp. 115-22.
