Full Description
Meso-Cenozoic Brazilian Offshore Magmatism: Geochemistry, Petrology and Tectonics presents detailed studies from different points-of-view on the geological—particularly magmatic—evolution of the Brazilian and South Atlantic Ocean offshore areas. This comprehensive book on geological events will help readers understand the holistic evolution of the area across geographical boundaries. Each chapter consists of an introduction, regional and local geology, methods, results, discussions, conclusions and supplementary material related to the geological development in island and seamounts in the Brazilian Platform and seafloor.
Contents
1. South Atlantic Ocean: postbreakup configuration and Cenozoic magmatism
2. Ocean fracture zones: their evolution and impact on tectonic and magmatism of the South and Southeast Brazilian continental margin
3. Brazilian Continental Margin morphology: ridges, rises, and seamounts
4. The singular St. Peter and St. Paul Archipelago, equatorial Atlantic, Brazil
5. Genesis and evolution of the Fernando de Noronha mantle plume
6. The Abrolhos Magmatic Province, the largest postbreakup magmatism of the Eastern Brazilian margin: a geological, geophysical, and geochemical review
7. Uplift and subsidence of the RGR: U-Th/He in apatite and EPFT in zircon
8. The role of the Rio Grande Rise on the continental Meso-Cenozoic alkaline magmatism in southwest Brazil
9. Vitória-Trindade seamounts: undersaturated alkaline series evolution from an enriched metasomatized source
10. Trindade Island: evolution of the geological knowledge
11. Martin Vaz Archipelago: the youngest magmatism in the Brazilian Territory
12. Brazilian Equatorial Margin: magmatic genesis and evolution
