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-Diffusivity and Heat-Capacity Measurements of Sandstone at High Temperatures Using Laser Flash and DSC Methods
Ilmutdin M. Abdulagatov,Ilmutdin M. Abdulagatov,Zumrud Z. Abdulagatova,Suleyman Nurulislanovich Kallaev,A. G. Bakmaev,Pathegama Gamage Ranjith +5 more
TL;DR: In this paper, the thermal diffusivity and heat capacity of natural sandstone samples were measured using a contact-free, laser-flash method and correlation equations were developed using the well-known theoretical asymptotic behavior of sandstone properties.

Plume-induced crustal convection: 3D thermomechanical model and implications for the origin of novae and coronae on Venus
TL;DR: In this paper, a 3D high-resolution thermomechanical model of mantle plume/diapir impingement into warm and thin lithosphere with Venus-like surface temperature is presented.

Modelling heat flow in a cold, high-altitude glacier: interpretation of measurements from Colle Gnifetti, Swiss Alps
Martin P. Lüthi,Martin Funk +1 more
TL;DR: In this article, the authors used a transient heat-flow model driven with a temperature history to find that substantial warming of the mean firn temperature at shallow depths has taken place over the last few decades, possibly enhanced by a degrading permafrost base.

Surface heat flow, crustal temperatures and mantle heat flow in the Proterozoic Trans-Hudson Orogen, Canadian Shield
Frédérique Rolandone,Claude Jaupart,Jean-Claude Mareschal,Clément Gariépy,G. Bienfait,C. Carbonne,R. Lapointe +6 more
TL;DR: The mean and standard deviation of heat flow values are 42 ± 9 mW m ¼ 2 as mentioned in this paper for the Canadian Shield, where the heat flow pattern follows the surface geology with a central area of low values over an ancient back arc basin (Kisseynew) and an ancient island arc (Lynn Lake Belt) made of depleted juvenile rocks.

Geomechanical modeling for CO2 storage in Nisku aquifer in Wabamun Lake area in Canada
TL;DR: In this paper, a coupled flow and geomechanical assessment model of the injection process of CO2 was developed, which couples the thermal flow model and geomagnetics model covering all layers from the basement to the surface, and incorporates the modeling of dynamic injection-induced fracture.

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.
