Photocatalytic oxidation of dissolved Mn(II) on natural iron oxide minerals

TL;DR: In this paper, the authors demonstrate rapid abiotic oxidation of Mn2+(aq) through photocatalytic reactions in the presence of natural Fe oxide minerals at rates comparable to those of currently known biotic/abiotic oxidation processes.
Journal ArticleDOI

Temperature fluctuations in the Archean ocean as trigger for varve-like deposition of iron and silica minerals in banded iron formations

TL;DR: In this article, the authors conducted laboratory experiments with the marine phototrophic Fe(II)-oxidizing bacterium Rhodovulum iodosum under simulated Archean ocean conditions.
Journal ArticleDOI

Mineral Facilitated Horizontal Gene Transfer: A New Principle for Evolution of Life?

TL;DR: It is argued that minerals hold an unrecognized potential for successfully transferring genetic material across environments and timescales to distant organisms and hypothesize that this process has significantly influenced the evolution of life.

Evidence from laminated chert in banded iron formations for deposition by gravitational settling of iron-silicate muds

TL;DR: The authors showed that laminated chert in banded iron formations from the Hamersley Group, Australia, and Ghaap Group, South Africa, preserve laminae of nanometer-sized particles of greenalite with textures that resemble the fabric of freshly deposited muds.
Journal ArticleDOI

Geological settings and metallogenesis of high-grade iron deposits in China

TL;DR: Based on a comprehensive review of current studies on these deposits, the authors suggests that the oxygen concentration in atmosphere played an important role for the formation of BIFs, whereas the tectonic setting and deep magmatic differentiation processes are more important for the other types.

Early oxidation of organic matter in pelagic sediments of the eastern equatorial Atlantic: suboxic diagenesis

TL;DR: Pore water profiles of total CO 2, pH, PO 3−4, NO − 3 plus NO − 2, SO 2− 4, S 2−, Fe 2+ and Mn 2+ have been obtained in cores from pelagic sediments of the eastern equatorial Atlantic under waters of moderate to high productivity as mentioned in this paper.

Sedimentary pyrite formation: An update

TL;DR: In this article, it was shown that organic matter appears to be the major control on pyrite formation in normal (non-euxinic) terrigenous marine sediments where dissolved sulfate and iron minerals are abundant.

A Neoproterozoic Snowball Earth

TL;DR: Negative carbon isotope anomalies in carbonate rocks bracketing Neoproterozoic glacial deposits in Namibia, combined with estimates of thermal subsidence history, suggest that biological productivity in the surface ocean collapsed for millions of years.

Chemical composition and evolution of the upper continental crust: Contrasting results from surface samples and shales

TL;DR: The average chemical composition of the upper continental crust (UC) as a function of age is estimated from chemical analyses, geologic maps, stratigraphic sections and isotopic ages as discussed by the authors.
