Photocatalytic oxidation of dissolved Mn(II) on natural iron oxide minerals
Haesung Jung,Haesung Jung,Xiaoming Xu,Xiaoming Xu,Biao Wan,Qian Wang,Olaf J. Borkiewicz,Yan Li,Hailong Chen,Anhuai Lu,Yuanzhi Tang +10 more
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.

Mineral Facilitated Horizontal Gene Transfer: A New Principle for Evolution of Life?
K. K. Sand,Stanislav Jelavić +1 more
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.
Journal ArticleDOI
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.

Geological settings and metallogenesis of high-grade iron deposits in China
Zhaochong Zhang,Hou-Min Li,Jian-Wei Li,Xie-Yan Song,Hao Hu,Li-Xing Li,Fengmei Chai,Tong Hou,Deru Xu,Deru Xu +9 more
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
Philip N. Froelich,Gary P. Klinkhammer,Michael L. Bender,Nile A. Luedtke,G.R. Heath,Doug Cullen,Paul Dauphin,Doug Hammond,Blayne Hartman,Val Maynard +9 more
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.
