Clays and clay minerals are common components in soils, sediments, and sedimentary
rocks, and they play an important role in many environmental processes. Iron is ubiquitous …

The ability of microorganisms to reduce iron in clay minerals has been well demonstrated by
literature up to now. However, the detailed interaction mechanisms between minerals …

Formation (Wufeng–Longmaxi) shale layers in the Sichuan Basin and its periphery is …

99Technetium (99Tc) is a fission product of uranium-235 and plutonium-239 and poses a
high environmental hazard due to its long half-life (t1/2= 2.13× 105y), abundance in nuclear …

Phyllosilicate deposits on Mars provide an opportunity to evaluate aqueous activity and the
possibility that habitable environments may have existed during the Noachian period there …

An in situ, atomic force microscopy-(AFM-)-based experimental approach is developed to
directly measure the kinetics of silica nucleation on model biosubstrates under chemical …

Authigenic carbonate minerals can preserve biosignatures of microbial anaerobic oxidation
of methane (AOM) in the rock record. It is not currently known whether the microorganisms …

Interactions between microbes and minerals have the potential to contribute significantly to
global cycles of various processes and serve as a link between the geosphere and life …

The illitization process of Fe-rich smectite (nontronite NAu-2) promoted by microbial
reduction of structural Fe3+ was investigated by using a thermophilic metal-reducing …

Clay minerals impart important chemical properties to soils, in part, by virtue of changes in
the redox state of Fe in their crystal structures. Therefore, measurement of Fe (III)/Fe (II) and …
