Abiotic synthesis during the interaction of ferrous chloride–rich silicic fluids with marble under high-grade metamorphic conditions

Proceedings of the National Academy of Sciences, Volume 122, number 35, September 2025.
Significant organic synthesis in geological processes is closely linked to the cycle of terrestrial carbon and at the origin of the beginning of life. Our research has revealed that the infiltration of ferrous chloride fluids and rich in dolomitic marble induced a …
