Photoemission and solvation of electrons from iron (II) ion in aqueous solution has been shown to lead to reduction of water to hydrogen (Cairns-Smith, 1981; Braterman et al., 1983). In the presence of dissolved carbon dioxide the photochemical reduction yields formate, oxalate and aldehydes, (Getoff 1963; ~kermark et al., 1980). These species are formed in dilute aqueous solution and are thus, in the absence of a selective concentration mechanism, of doubtful importance for probiotic synthesis… 

Anion selective minerals as concentrators and catalysts for RNA precursor components

Synthesis and investigation of such minerals show common representatives to be efficient concentrators of cyanide and ferrocyanide, phosphate and diphosphate (pyrophosphate), carbonate and

Anoxic photochemical oxidation of siderite generates molecular hydrogen and iron oxides

It is proposed that the photochemistry of Earth-abundant minerals with wide band gaps would have potentially played a critical role in shaping the biogeochemical evolution of early Earth.

Montmorillonite: A multifunctional mineral catalyst for the prebiological formation of phosphate esters

This research established that the montmorillonite performs four different functions in its role as catalyst: Binding one of the substrate molecules (3′-AMP), Activating the second substrate (DAMN), Catalyzing the formation of 2′, 3′-cAMP, and releasing the reaction product so another substrate molecules can bind to the montMorillonite.

It is speculated that life originated in a small, shallow body of water containing concentrated prebiotic organic feedstocks, inorganic compounds, and catalytic agents in a diversity of microenvironments on a suitable planet with an atmosphere in an appropriate thermodynamic state, such as Earth.

Evolution of photosynthetic reaction centers: insights from the structure of the heliobacterial reaction center

The heliobacterial RC is homodimeric and loosely binds (and reduces) quinones, which supports the view that it retains more ancestral features than its homologs from other groups, and a robust comparison of all known RC types with available structural data is performed.

Electronic structures of siderite (FeCO3) and rhodochrosite (MnCO3): Oxygen K-edge spectroscopy and hybrid density functional theory

Abstract Electronic transitions of siderite and rhodocrosite may have played a role in prebiotic synthesis by photochemical reactions in the Archean. In the work described here, I measured the

Precambrian solution photochemistry, inverse segregation, and banded iron formations

SOLAR radiation on an early Precambrian sea would generate short-lived excited species near the surface of the water. Many of the species would be powerful oxidising or reducing agents. Despite

Photo-oxidation of hydrated Fe2+—significance for banded iron formations

The Precambrian banded iron formations (BIFs) are the major iron ore sources on the Earth. They consist of extensive iron-rich and iron-poor layers within siliceous sedimentary rocks1,2. The banding
