Experimental study of serpentinization and abiotic CH$_4$ production in martian conditions.
Year: 2022
Type: conference-paper
Abstract: The presence of methane on Mars remains highly debated in particular with contrasted detection results from Curiosity rover [1] and TGO [2]. In addition, the possible methane cycle is also poorly known: source(s) and removal process(es) remain currently undefined; and it is not known yet if this methane emissions might be related to a biological activity. Because of orbital detection of serpentine on Mars [3], and of the mafic-ultramafic nature of Mars ancient crust, a putative abiotic candidate source is serpentinization associated with Sabatier reaction. The aim of this work is to experimentally study the production capacity of H2 and mainly CH4 by those abiotic processes in martian conditions to determine the viability of this origin.
