1 th SSAGI South American Symposium on Isotope Geology 9 th South American Symposium on Isotope Geology Program 1 and Abstracts

2 Message from the Organizing Committee Dear Participants, The organizing committee of the 9 th South American Symposium on Isotope Geology - 9 th SSAGI - has the great honor to welcome all the participants to São Paulo, Brazil. Seventeen years have been gone since the Center of Geochronological Research - CPGeo - of the Institute of Geosciences of the University of São Paulo has organized the first SSAGI. After 7 other events, which were held in many countries of South America, including Argentina, Chile, Uruguay and Colombia, SSAGI is back to São Paulo. The 2014 meeting will celebrate the 50 th anniversary of CPGeo, which was created back in 1964 by Umberto Cordani and his (small) group. Since then CPGeo has became a major research center for isotope geology in South America. The meeting will last 3 days, and will include 12 keynote speakers, other 12 invited oral presentations and poster sessions to present state-of-the-art themes in different fields of isotope geology, such as: crustal and mantle evolution, geochronology of igneous, metamorphic and sedimentary processes, isotopes applied to chemostratigraphy and seawater evolution, application of isotopes to investigate hydrocarbon generation, environmental issues, paleoclimate, paleoceanography, and the new developments in isotopes and geochronology. We hope you enjoy the scientific program we prepared for you. 9 th South American Symposium on Isotope Geology 3 We want to thank the keynote speakers and the invited ones for accepting our invitation. The members of the organizing committee and the scientific committee are thanked for preparing the scientific program. The sponsors and exhibitors that provided the means to make possible this symposium are warmly acknowledged. Finally, we are grateful to the Brazilian science agencies and to the Brazilian Geological Society for their generous support to this meeting. We wish you all a very pleasant meeting with fruitful scientific discussions and an enjoyable stay in São Paulo! The Organizing Committee

4 AT A DEPTH OF SEVEN THOUSAND METERS, WE FOUND OIL, INSPIRATION AND RESPECT. 9 th South American Symposium on Isotope Geology 5 We re world leaders in the exploration and production of deepwater and ultra deepwater oil, and our operations in Brazil s pre-salt layer have earned us a strategic position in the task of meeting the world s ever-increasing energy demand. We invest in the diversification of the energy mix through the use of renewable sources. In addition, we comply with the principles of the United Nations Global Compact and we ve been listed on the Dow Jones Sustainability Index for eight consecutive years. Petrobras. Promoting social and environmental responsibility is just as important as growing.
