Spatial variability of methane (CH4) on Mars suggests the presence of localized subsurface sources. Here, we show that olivine hydration in the Martian regolith and crust may be a major CH4 source, which contributed significantly to the warming of early Mars. Methane production is kinetically and thermodynamically favored during low‐T aqueous alteration of olivine‐rich rocks. Sustained release of CH4 on present‐day Mars may come through the breakdown of ancient CH4 hydrates and from springs… 
Geology of possible Martian methane source regions
Geologic setting of serpentine deposits on Mars
Serpentine, recently discovered on Mars using Mars Reconnaissance Orbiter data, is uncommon but found in three geologic settings: (1) in mélange terrains at the Claritas Rise and the Nili Fossae, (2)
Interglacial clathrate destabilization on Mars: Possible contributing source of its atmospheric methane
The presence of methane has been recently detected in the martian atmosphere, suggesting a contemporary source such as volcanism or microbial activity. Here we show that methane may be released by

TLDR
The results indicate that in situ abiotic synthesis of CH4 in low-temperature serpentinizing environments may be much more limited than some recent studies have suggested and that shallow serpentinization environments where a separate gas phase is present may be more favorable for abiotic synthesizing ofCH4.
Removal of water from Mars' hydrosphere by serpentinization
One of the most plausible mechanisms proposed so far to explain the presence of methane in Mars’ atmosphere is serpentinization of ultramafic rocks from crustal carbon [1]. This process, to be

Seepage in Serpentinised Peridotites and on Mars
This book has mainly addressed the classical seepage of natural gas of biotic (microbial and thermogenic) origin in sedimentary rocks. It is also known that methane and other light hydrocarbons can

Ultramafic rocks, composed mainly of olivine and pyroxenes, are a major component in the lithosphere of early terrestrial planets, where they formed by direct crystallization of mantle-derived magmas

Abstract If the recently observed young gullies on Mars represent seeps or outflows of aqueous fluid, that fluid must be highly concentrated brine to be even moderately stable under current martian
H2-rich fluids from serpentinization: geochemical and biotic implications.
TLDR
The catalytic properties of FeNi3 allow complex organic compounds to form within serpentinite and, when mixed with atmospherically produced complex organic matter and waters that circulated through basalts, constitutes an attractive prebiotic substrate.
Discovery of Olivine in the Nili Fossae Region of Mars
We have detected a 30,000-square-kilometer area rich in olivine in the Nili Fossae region of Mars. Nili Fossae has been interpreted as a complex of grabens and fractures related to the formation of
Hydrocarbons in Hydrothermal Vent Fluids: The Role of Chromium-Bearing Catalysts
TLDR
Results suggest that the chromium component in ultramafic rocks could be an important factor for FTT synthesis during water-rock interaction in mid-ocean ridge hydrothermal systems, which could help to support microbial communities now recognized in the subsurface at deep-sea vents.

Abiogenic methane formation and isotopic fractionation under hydrothermal conditions
TLDR
Isotopic fractionation by the catalyst resulted in delta(13)C values of the CH(4) formed that are as low as those typically observed for microbial methane, which suggests that abiogenic methane may be more widespread than previously thought.
