Abstract A possibly prominent role for Green Rust minerals in life's emergence is inferred from a comparison of their structural, mechano-dynamic and electrochemical properties and of the layout of bioenergetic, i.e. free energy converting processes in extant organisms. From fundamental thermodynamic considerations, the conversion of environmental free energy into the decrease of entropy that defines life is an indispensable ingredient for life to emerge. A specific scenario for life's emergence mediated by Green Rust minerals in the framework of the alkaline hydrothermal vent hypothesis is proposed.
Highlights The potential roles of clay minerals in the emergence of life (EoL) are reassessed. Fe-LDHs (Green Rusts, GR) are singled out as particularly promising candidates. Previously characterized relevant properties of Green Rusts are reviewed. Biology-inspired putative but plausible GR-mediated processes are discussed. A scenario for a GR-assisted EoL resembling bioenergetic systems is proposed.
