Widespread abiotic methane in chromitites [PDF]
Scientific Reports, 2018 Recurring discoveries of abiotic methane in gas seeps and springs in ophiolites and peridotite massifs worldwide raised the question of where, in which rocks, methane was generated.

Chromitite layers indicate the existence of large, long-lived, and entirely molten magma chambers [PDF]
Scientific Reports, 2022 The classical paradigm of the ‘big magma tank’ chambers in which the melt differentiates, is replenished, and occasionally feeds the overlying volcanos has recently been challenged on various grounds.

Noble metal catalyst detection in rocks using machine-learning: The future to low-cost, green energy materials? [PDF]
Scientific Reports, 2023 Carbon capture and catalytic conversion to methane is promising for carbon–neutral energy production. Precious metals catalysts are highly efficient; yet they have several significant drawbacks including high cost, scarcity, environmental impact from the

Diversities of chromite mineralization induced by chemo–thermal evolution of the mantle during subduction initiation [PDF]
Nature CommunicationsOphiolites, mostly formed via subduction initiation at proto-forearcs, exhibit a unique variation of mantle-derived magmatism from MORB-like to low-Ti tholeiitic and boninitic-like affinities.

Platinum-bearing chromite layers are caused by pressure reduction during magma ascent [PDF]
Nature Communications, 2018 Some basaltic melts become first superheated upon their ascent towards the Earth’s surface and then saturated in chromite alone after cooling in shallow chambers.

GLAUKOSPHAERITE FROM CHROMITITES OF THE VOYKAR-SYNYA MASSIF, POLAR URALS – THE FIRST RELIABLE FIND IN RUSSIA [PDF]
Минералогия, 2023 Glaukosphaerite and mcguinnessite (carbonates of the rosasite-malachite group) are found in chromitites of the Burkhoyla area, which is located in the northern part of the Voykar-Synya ultramafic massif (Polar Urals).
