Welcome to the official website of the
11th International GeoRaman Conference

GeoRaman 2014 welcomed scientists from all over the world to join us, to present their newest studies, to participate in active discussions, and to build future collaborative relationships. This website serves as a permanent record of all the memomorable presentations, events and happenings from the very successful 11th GeoRaman conference in St. Louis.


At the first GeoRaman Conference in 1986 (Paris, France), I was a PhD student of Professors Michel Delhaye and Paul Dhamelincourt at LASIR. These two scientists designed the first Raman microprobe, and introduced this technology to the scientific community around the world. They are not the discoverers of the Raman Effect per se, but their new concept of Raman instrumentation opened a door. That door allows complicated, dirty, even non-crystalline, natural samples to be investigated by laser Raman spectroscopy, which is an intrinsically weak physical process but an extremely powerful tool for molecular characterization. The contributions of these two great human beings (now deceased) are to be remembered.

Since 1986, various Raman systems have been developed for use in the scientific laboratory, industrial process control, homeland security, terrestrial field expeditions, and robotic undersea and planetary explorations. Benefitting from technological developments, the scientific applications of laser Raman spectroscopy have deepened and broadened over the years. Enhanced Raman technology has allowed us to study the effects of high pressure and temperature in the Earth's mantle and core, the interaction of geological fluids with their physical and chemical surroundings, the results of biological activity in recent and ancient environments, the properties of biologically precipitated minerals and how they differ from their geological counterparts, products and processes in current and paleo-environments, human cultural heritage as reflected in art and artifacts, and the nature of extraterrestrial processes happening now and in the past on other planetary bodies, as well as during the formation of our solar system.

Past and current International GeoRaman Conferences try to capture what is new in both the science and technology in all these fields. We also attempt in these conferences to generate new ideas, questions, and collaborations, as well as to introduce new researchers to the excitement of the field of laser Raman spectroscopy.

During the preparation of GeoRaman XI, we have been extremely fortunate to get financial support from many sponsors, scientific guidance from the GeoRaman International Science Advisory Committee (GRISAC), highly productive collaboration among members of GeoRaman XI's United States Organization Committee (USOC), and timely and consistent help on logistics from the Conference Assistants. I would like to express my deepest personal appreciation to all of them. The USOC wishes you a fruitful GeoRaman XI conference in St. Louis.
