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] |
