Abiotic methane ordinarily forms at temperatures much higher than those that occur in the rocks at Yanartaş. However, ruthenium is present in the igneous rocks under the flames, and is believed to act as a catalyst, permitting the formation of methane at the lower temperatures (i.e., below 100 °C) that occur at Yanartaş.

Magma consists of liquid rock that usually contains suspended solid crystals. [14] As magma approaches the surface and the overburden pressure drops, dissolved gases bubble out of the liquid, so that magma near the surface consists of materials in solid, liquid, and gas phases.
