TL;DR: In this paper, the authors present a number of geological observations in extensional contexts, either continental rifts or back-arcs, that show different situations of potential coupling between asthenospheric flow and crustal deformation.

TL;DR: In this article, the authors used electron paramagnetic resonance (EPR) and Fourier transform infrared spectroscopies to track the evolution of suspended matter using a ubiquitous chemical species, FeIII complexed to organic matter (FeOM).

TL;DR: In this article, the authors illustrate the bases and limits of this approach by reviewing some studies on biogenic magnetites and carbonates and suggest developing a more comprehensive mechanistic understanding of how life controls mineral nucleation and growth and induces potential specific features.

TL;DR: In this article, the authors investigated the speciation of aluminum in the clay-size fractions of eight horizons of waterlogged podzols lying in a depression of a plateau.

TL;DR: In this paper, molecular dynamics calculations of a complex SiO2+B2O3+Al2O 3+ZrO 2+Na2O+CaO glass with surfaces revealed the formation of outer layers having different structural properties than the bulk glass.
Abstract: Molecular dynamics calculations of a complex SiO2+B2O3+Al2O3+ZrO2+Na2O+CaO glass with surfaces revealed the formation of outer layers having different structural properties than the bulk glass. Alkali cations tend to migrate toward the surface, lowering the coordination number of the trivalent elements in the subsurface layer. The outer layer is also enriched in oxygen. Depolymerization leads to the formation of slightly larger rings on average. Atom mobility is enhanced in the lower density layers, as shown by the application of an external electric field and during simulated displacement cascades. Although these results are consistent with previously published findings, it is difficult to assess the actual scope of these surface effects (estimated by molecular dynamics to extend to a depth of about 10 A) because this approach does not take into account the effects of long-range diffusion or of the interface with the surrounding environment.
