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

Enhanced conduction in steady, vertical flows of water, steam and carbon dioxide in a porous medium
G. J. Weir,W. M. Kissling +1 more
TL;DR: In this paper, the steady, vertical transport of water, energy and carbon dioxide in a two-phase porous medium is analyzed when capillarity can be ignored and conditions are derived which allow three values of saturation for a given flux.

Thermal conductivity of Triassic evaporites
Cristina Pauselli,Gianluca Gola,Giorgio Ranalli,P Mancinelli,F Trippetta,P Ballirano,Massimo Verdoya +6 more
TL;DR: In this article, an exhaustive review of the literature allows the determination of the conductivity for the main evaporitic minerals and of their variation with temperature, and in order to assess the effects of compositional variability, select six samples of Triassic evaporites from the Apennines (from both outcrops and boreholes) and measure their mineralogical composition and thermal conductivity.

TL;DR: In this article, a methodology for the determination of lithology-based thermal conductivities at a regional scale is proposed, assigning a saturated and unsaturated thermal conductivity to each stratigraphic unit encountered in the region.

TL;DR: In this article , a correction factor was proposed to improve the accuracy of the weighted geometric mean model for determining the thermal conductivity of reservoir rocks, which is the most popular theoretical model for estimating thermal conductivities.

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.
