TLDR
In this paper, if the hydraulic permeability of crustal material is sufficiently high, convection driven advection of heat can be an equally or even much more efficient transfer mechanism, provided sufficiently strong driving forces are supplied by forced or free convection systems.Abstract:
(1) If the hydraulic permeability of crustal material is sufficiently high, convection driven advection of heat can be an equally or even much more efficient transfer mechanism, provided sufficiently strong driving forces are supplied by forced or free convection systems. This is often the case in sedimentary basins. However, fluid driven heat advection can be important also in crystalline rocks and on a crustal scale (Etheridge et al., 1983, Torgersen, 1990, Clauser, 1992).read more

Generation of fine hydromagmatic ash by growth and disintegration of glassy rinds
TL;DR: In this article, the authors consider a process of hydromagmatic ash formation that involves repeated growth and disintegration of glassy rinds on pyroclast surfaces as they deform within turbulent flows.

Utility of bromide and heat tracers for aquifer characterization affected by highly transient flow conditions
TL;DR: In this article, a tracer test using both bromide and heat tracers conducted at the Integrated Field Research Challenge site in Hanford 300 Area (300A), Washington, provided an instrument for evaluating the utility of tracers for aquifer characterization.

Large‐scale rigid‐body rotation in the mantle wedge and its implications for seismic tomography
Weronika Gorczyk,Taras Gerya,Taras Gerya,James A. D. Connolly,David A. Yuen,Maxwell L. Rudolph +5 more
TL;DR: In this paper, a combined finite difference and marker-in-cell technique was used to simulate the intraoceanic subduction of the mantle wedge, and the authors investigated the parameters controlling the occurrence and long-term stability of such rigid, rotating structures.

From continental rifting to seafloor spreading: Insight from 3D thermo-mechanical modeling
Jie Liao,Taras Gerya +1 more
TL;DR: Using 3D thermo-mechanical coupled visco-plastic numerical models, Wang et al. as discussed by the authors investigated the complete extension process and the inheritance of continental rifting in oceanic spreading.

A model for Ischia hydrothermal system: Evidences from the chemistry of thermal groundwaters
R. Di Napoli,Alessandro Aiuppa,Alessandro Aiuppa,Sergio Bellomo,Lorenzo Brusca,Walter D'Alessandro,E. Gagliano Candela,Manfredi Longo,Giovannella Pecoraino,Mariano Valenza +9 more
TL;DR: In this article, the chemical and isotopic composition of 120 groundwater samples, collected during several sampling surveys from 2002 to 2007, is reported. And an assessment of the thermal budget for Ischia hydrothermal system is also presented, in the attempt to derive a first estimate of the size and rate of degassing of the magmatic reservoir feeding the gas emissions.

Thermophysical properties of materials
TL;DR: In this paper, the authors consider the thermal properties of harmonic lattice vibrations in real crystals and atomic vibrations in defect lattices, as well as the properties of anisotropic and polycrystalline materials.

Thermal Conductivity of Porous Media. I. Unconsolidated Sands
W. Woodside,J. H. Messmer +1 more
TL;DR: In this paper, the problem of determining the effective thermal conductivity of a two-phase system, given the conductivities and volume fractions of the components, is examined, and an equation based on a three-element resistor model is proposed.

The role of the fluid phase during regional metamorphism and deformation
TL;DR: In this paper, a Rayleigh-Darcy modeling of a uniformly permeable, crustal slab is used to show that convective instability of metamorphic fluid is expected at the permeabilities suggested for the high Pf conditions, and that large scale convective cells operating in overpressured, but capped systems may provide a satisfactory explanation for the large fluid/rock ratios and extensive mass transport demonstrated for many low and medium-grade metamorphin-ments.

Thermal conductivity of rock‐forming minerals
TL;DR: The thermal conductivities /K/ of rock forming minerals reveal K as linear function of density for constant mean atomic weight as discussed by the authors, where k is the number of atoms in a given sample.
