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

Thermal conductivity map of the Avila region (Spain) based on thermal conductivity measurements of different rock and soil samples
Cristina Sáez Blázquez,Arturo Farfán Martín,Ignacio Martín Nieto,Pedro Carrasco García,Luis Santiago Sánchez Pérez,Diego González Aguilera +5 more
TL;DR: In this article, a thermal conductivity map of an area geographically placed in the center of Spain, the province of Avila, is proposed, based on a thermal response test.

Decoupled thermal and mantle helium anomalies: Implications for the transport regime in continental rift zones
TL;DR: In this paper, a combination of thermal, helium isotope, and major element data of mineral waters with numerical simulations of flow and heat transport leads to a profound understanding of crustal-scale transport processes and allows a clear distinction between diffusion and flow dominated regimes.

The influence of ambient fault temperature on flash‐heating phenomena
TL;DR: In this article, the effects of elevated ambient fault temperature, up to that at the base of the Earth's seismogenic zone, on the flash-heating behavior of quartzite, Westerly granite, and India gabbro were explored.

Air circulation in deep fractures and the temperature field of an alpine rock slope
TL;DR: In this article, the authors analyzed a unique set of temperature measurements from an alpine rock slope at ~2400m a.s.l. in southern Switzerland and found that venting air changed temperature gradually from ~3 to 2'°C between December and May, which is similar to the rock temperature at around 50'm depth.

Ultra-hot Mesoproterozoic evolution of intracontinental central Australia
TL;DR: In this article, a series of two dimensional, fully coupled thermo-mechanical-petrological numerical models were used to investigate the plausibility of initiating and prolonging ultra-high temperature (UHT) conditions under model setup conditions appropriate to the inferred tectonic setting and lithospheric architecture of the Musgrave Province.

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.
