This is a thematic project to study the geological evolution of Archaean terranes of the São Francisco Craton and the Borborema Province where South America’s oldest rocks were discovered (ca. 3,500 Ma). The project has started in May 2013 and will last until April 2017 with financial support from the São Paulo Research Foundation (FAPESP). The methods and techniques to be employed include extensive fieldwork, cutting edge U-Pb and Sm-Nd geochronology, major and trace element geochemistry, as well as radiogenic and stable isotope geochemistry. The project is a contribution to the IGCP-SIDA Project 599 – The Changing Early Earth. For more information about the project, please click here.
