- •
Methane-rich water springs and seeps discovered in the Ronda peridotite massif.
- •
Stable C and H isotope ratios indicate a predominant abiotic origin of methane.
- •
Methane is not generated from the C in the hyperalkaline water.
- •
Methane is released as bubbles and diffuse seepages.
- •
Gas follows migration pathways independent from the hyperalkaline springs.
