Water-rock interaction and life

Water-rock interactions play a critical role in the origin, existence, and prospects of life. Minerals are sources of energy and nutrients. Life uses aqueous chemical gradients to access and use minerals. Chemical disequilibrium, therefore, represents one type of biotic signature. Life also controls other types of disequilibrium, including isotopic disequilibrium and morphology. Water is a fund...

Influence of phyllosilicates on fault strength in the brittle–ductile transition: insights from rock analogue experiments

Despite the fact that phyllosilicates are ubiquitous in mature fault and shear zones, little is known about the strength of phyllosilicate-bearing fault rocks under brittle–ductile transitional conditions where cataclasis and solution-transfer processes are active. In this study we explored steady-state strength behaviour of a simulated fault rock, consisting of muscovite and halite, using brin...

The Brittle-Ductile Transition in Mixtures of Rock and Ice: Experiments at Planetary Conditions

Introduction: Mars exhibits a wide variety of landforms that are indicative of ductile flow, ranging from the viscous creep of ice-rich permafrost [1] to the glaciation of thick Martian ice sheets [2] to the surface mobility of thin debris flows [3]. All of these flow features probably contain significant amounts of dust, which for example will likely be present throughout the impact-disrupted ...

Water-induced convection in the Earth’s mantle transition zone

[1] Water enters the Earth’s mantle by subduction of oceanic lithosphere. Most of this water immediately returns to the atmosphere through arc volcanism, but a part of it is expected as deep as the mantle transition zone (410–660 km depth). There, slabs can be deflected and linger before sinking into the lower mantle. Because it lowers the density and viscosity of the transition zone minerals (...

Numerical Study on Crack Propagation in Brittle Jointed Rock Mass Influenced by Fracture Water Pressure

The initiation, propagation, coalescence and failure mode of brittle jointed rock mass influenced by fissure water pressure have always been studied as a hot issue in the society of rock mechanics and engineering. In order to analyze the damage evolution process of jointed rock mass under fracture water pressure, a novel numerical model on the basis of secondary development in fast Lagrangian a...
