NITROGEN AND NOBLE GASES IN MARTIAN METEORITE TISSINT

Introduction: The Martian meteorite, Tissint, an olivine-phyric shergottite, has generated great excitement for its pristine nature and its scientific potential for understanding Mars [1-4]. Here we report results of nitrogen and noble gas isotopic study to understand the contribution from different reservoirs to make up Tissint. Nitrogen and noble gas data from Martian meteorites define signature of modern Martian atmosphere, ancient Martian atmosphere and Martian interior. Chassignite host interior components, while shergottites and nakhlites contains both interior and atmosphere components.
