Magmatic Intrusions From a Hydraulic Fracture Modeling Perspective
Brice Tanguy Alphonse Lecampion, Andreas Möri
The emplacement of magmatic intrusions in the earth’s crust has been investigated for decades. The driving mechanism is the density difference between the fluid and the rock. In the absence of heterogeneities, this difference creates a constant buoyancy fo ...
2023Enhancing Entropy and Enthalpy Fluctuations to Drive Crystallization in Atomistic Simulations
Pablo Miguel Piaggi, Michele Parrinello
Crystallization is a process of great practical relevance in which rare but crucial fluctuations lead to the formation of a solid phase starting from the liquid. As in all first order first transitions, there is an interplay between enthalpy and entropy. B ...
American Physical Society2017Multilevel and Local Timestepping Discontinuous Galerkin Methods for Magma Dynamics
Discontinuous Galerkin (DG) method is presented for numerical modeling of melt migration in a chemically reactive and viscously deforming upwelling mantle column. DG methods for both advection and elliptic equations provide a robust and efficient solution ...
Springer2015Theory and laboratory experiments of elastic wave scattering by dry planar fractures
Remote sensing of fractures with elastic waves is important in fields ranging from seismology to nondestructive testing. In many geophysical applications, fractures control the flow of fluids such as water, hydrocarbons or magma. While previous analytic de ...
American Geophysical Union2011Are high He-3/He-4 ratios in oceanic basalts an indicator of deep-mantle plume components?
The existence of a primordial, undegassed lower mantle reservoir characterized by high concentration of He-3 and high He-3/He-4 ratios is a cornerstone assumption in modern geochemistry. It has become standard practice to interpret high He-3/He-4 ratios in ...
