Abstract Recent observations have evidenced traces of methane ( CH 4 ) heterogeneously distributed in the martian atmosphere. However, because the lifetime of CH 4 in the atmosphere of Mars is estimated to be around 300–600 years on the basis of photochemistry, its release from a subsurface reservoir or an active primary source of methane have been invoked in the recent literature. Among the existing scenarios, it has been proposed that clathrate hydrates located in the near subsurface of Mars… Expand

Stability and composition of CH4-rich clathrate hydrates in the present martian subsurface
Abstract In the past years, multiple detections of methane in Mars' atmosphere have raised numerous questions about its potential sources. Independently of methane formation mechanism(s), CH4Expand
Since 2003, several detections of methane in the atmosphere of Mars were reported from Earth-based and Mars orbit instruments [1–5] with abundances up to tens of parts per billion by volume (ppbv).Expand
Volatile Trapping in Martian Clathrates
Thermodynamic conditions suggest that clathrates might exist on Mars. Despite observations which show that the dominant condensed phases on the surface of Mars are solid carbon dioxide and water ice,Expand
Methane clathrates in the solar system.
Thermodynamic equilibrium calculations show that methane-rich clathrate layers may exist on Pluto as well, and their presence is invoked in the satellite's subsurface as a means of replenishing its atmosphere with methane via outgassing episodes. Expand
Martian zeolites as a source of atmospheric methane
Abstract The origin of the martian methane is still poorly understood. A plausible explanation is that methane could have been produced either by hydrothermal alteration of basaltic crust or byExpand

ABSTRACT Clathrate hydrates are particular solids that planetologists study in detail because those solids may be present in several bodies of the solar system, such as Mars, comets, and the icyExpand
Kinetics of methane clathrate formation and dissociation under Mars relevant conditions

Thermodynamic modelling of clathrate hydrates in the atmosphere of Mars

Volatile inventories in clathrate hydrates formed in the primordial nebula.
This work uses a statistical thermodynamic model to investigate the composition of clathrate hydrates that may have formed in the primordial nebula, and finds that Kr, Ar and N2 can be efficiently encaged in clath Rate hydrate formed at temperatures higher than approximately 48.5 K in the primitive nebula.

Methane clathrate hydrates as a potential source for martian atmospheric methane
Abstract Small amounts of methane have been detected in the atmosphere of Mars, though the actual sources of the gas remain unknown. Thermodynamic conditions on Mars suggest that gas clathrateExpand
