Abstract

The Workshop on Volatiles in the Martian Interior was held Nov. 3 – 4, 2014 at the Lunar and Planetary Institute in Houston, TX (http://www.hou.usra.edu/meetings/volatiles2014/) and gathered scientists from diverse disciplines to discuss the state of knowledge of volatiles in the interior of Mars. The goals were to discuss the latest developments in the field, synthesize our current knowledge, and develop primary scientific questions that still need to be addressed. The workshop included discussions from studies of meteorites, remote sensing, laboratory experimental investigations, in situ surface investigations, astrobiological implications, and geophysical and geochemical modeling. The workshop started with an overview of volatile reservoirs, including the current and ancient atmosphere. It was then organized into sessions by volatile components: chlorine, water, sulfur, and carbon, with highlights on bulk content and reservoirs, effects on mantle melting and basalt genesis, degassing to the crust and atmosphere, and potential for habitability. The martian meteorites’ bulk and mineral chemistries were the main tools used to constrain the volatile contents of the interior. This abstract will summarize the key findings of the workshop and the primary open questions.
