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.
List of 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
About the author
Dr. Anderson Costa dos Santos is a young scientist investigating the Vitória-Trindade Ridge (VTR) magmatism and its relation to the Trindade Mantle Plume which expressed large alkaline igneous provinces inland Brazilian territory. Dedicating his earlier years to teaching optical mineralogy and magmatic processes at Rio de Janeiro State University, he found his passion on seamounts and islands evolution. Dr. Costa dos Santos majored in Geology at Rio de Janeiro State University and obtained his masters and doctorate in Science by the same institution.Peter Christian Hackspacher is a Senior Professor for Geotectonics at the Department of Petrology and Metallogeny, Institute of Geociences and Exact Sciences,State University São Paulo, IGCE/UNESP. He’s the senior researcher and leader of the Tectonic Group CNPq, as well as the Leader of the Center for Thermochronometry and Thermochronology DPM/IGCE/UNESP. He currently acts as the Director of the Institute for Oceanic Studies at UNESP. His research is focused in tectonics and geochronology with special interest in Precambrian and Phanerozoic terranes related to the PT history through the time, in Brazil, Peruvian Andes, and southwestern Africa. He is engaged in fundamental and applied research of low and high temperature thermochronometry and thermochronology.
