Timescales of carbon turnover in soils with mixed crystalline mineralogies

open access: yes, 2017
Organic matter–mineral associations stabilize much of the carbon (C) stored globally in soils. Metastable short-range-order (SRO) minerals such as allophane and ferrihydrite provide one mechanism for long-term stabilization of organic matter in young ...

Spin crossover in ferropericlase from first-principles molecular dynamics

open access: yes, 2015
Ferropericlase, (Mg,Fe)O, is the second-most abundant mineral of the Earth's lower mantle. With increasing pressure, the Fe ions in the material begin to collapse from a magnetic to non-magnetic spin state.
