CALL FOR POSTERS

Poster presenters need to submit an abstract of no more than 2000 characters (including spaces)

by 15/10/2015. The abstracts (electronic format only –pdf files) will be published in digital proceedings (USB flash-drive).

If you are interested in giving a poster, thank you for sending the title of your abstract and your text of abstract together with your affiliation and contact details to registration@lestudium-ias.fr as soon as possible.

Introduction

Geology and geochemistry provide the boundary conditions for our understanding of life on Earth. Central to this understanding are rock-water-carbon interactions between carbon and the environment. This colloquium is being held to create an international think-tank to examine the origin(s) of life and evolution of early life, and specifically the influence and importance of hydrothermal activity on rock-water-carbon reactions. Understanding of the geological/ geochemical context for the origin of life and for early life on Earth will help concentrate and support efforts to find life elsewhere in the Solar System and even beyond. These activities are timely given the upcoming European/Russian mission to Mars, Exomars 2018, whose objective is to search for traces of past life. Immediately following this mission is the first step in the multi-mission scenario for the return of samples coordinated by NASA for 2020.
