Ricardo Trindade contributed to a better understanding of the tectonic history of South America, defining ancient mountain belts and oceans (among them, the Clymene ocean) and refined the cycle of supercontinents, particularly improving the reconstructions of Nuna, Rodinia and Godwana with a remarkable record of new key poles for different cratons in South America and Africa. He also contributed to the discussion on the extreme climatic events of the Neoproterozoic and their biological consequences using magnetism and C-O-N-S and Sr isotopes from carbonate successions from South America, Africa and Asia. More recently, he has determined the evolution of the South Atlantic geomagnetic anomaly at the centennial to millennial scales using lake sediments, speleothems and archeological material and its origins related to the reverse flux patches at the core-mantle boundary. Member of the Brazilian Academy of Sciences, he has received several national awards.
