11th South American Symposium on Isotope Geology


Dear Participants

From the heart of South America, the organizers of the 11th SSAGI – Latin America (11th South American Symposium on Isotope Geology) welcome all participants and guests to Cochabamba Bolivia. The SSAGI is organized every two years, with the goal of providing a discussion of methods and applications of stable and radioactive isotopes in the Earth Sciences and the advances achieved in recent years, in this field of science.

The idea to organize a SSAGI in Bolivia was born in 2006 in Punta de Este, Uruguay but it was not until the 10th SSAGI at Puerto Vallarta, Mexico that it came into an agreement.

The symposium will take place during 3 days, including the participation of keynote speakers, plenary talks, as well as guest talks and numerous poster presentations with state-of-the-art topics in different fields of isotope geology.

We thank you all for your participation to convert the 11th SSAGI into an international symposium linking geoscientists from South America, North America, Europe and other countries of the world  in themes related to isotope geology.

We hope you will enjoy the meeting and have a pleasant stay in Bolivia.

Sincerely yours


The 11th SSAGI will be held from July 22nd to 25th, 2018, in Cochabamba, Bolivia. The most attractive touristic city in Bolivia, characterized by nice and spring weather in South America.

Cochabamba has an International Airport with excellent access by air and direct connections to a number of cities in South America.

The symposium will be held at Universidad Catolica Boliviana San Pablo, Cochabamba.
