The 28th International Meeting on Organic Geochemistry (IMOG 2017) will be held in Florence (Italy), during September 17-22, 2017. For the first time the conference will be organized by the European Association of Organic Geochemists in cooperation with the House of Geoscience (HOG). IMOG 2017, the official biennial conference of the European Association of Organic Geochemists (EAOG) is the largest meeting on Organic Geochemistry. The EAOG (founded in 1983) has over 450 members from all around the world and seeks to promote organic geochemistry in its broadest sense. The guiding principle of the IMOG meetings is to encourage presentation, communication and discussion of research results carried out in academia and industry in the fields of Organic Geochemistry with topics ranging from Biogeochemistry to Petroleum Geochemistry. A scientific programme will be designed to fulfil this goal, with an outstanding collection of oral and poster presentations to cover the diverse aspects of organic geochemistry research, its application and integration into studies highly relevant for the advance of the science and industrial applications.
