Schematic image of proto-phyllosilicate formation on the olivine surface. a Dissolution of olivine into the organic fluid. Magnesite formation also proceeded. b Precipitation features cover the olivine surface. Etch pits evolved with the dissolution progress. These features were confirmed using SEM. c Flake-like particles evolved to a tubular structure, from amorphous to crystalline, in the precipitation features. These features were confirmed using TEM. d Formation of crystalline proto-phyllosilicates on the olivine surface
