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

Possibilities of using thermal mass in buildings to save energy, cut power consumption peaks and increase the thermal comfort
TL;DR: In this article, the authors generate knowledge to enable us to take advantage of heat storage in heavy building structures with regard to as energy savings, better thermal indoor climate, and reduced peak powers.

Blueschists and Blue Amphiboles: How much Subduction do they Need?
Walter V. Maresch,Taras Gerya +1 more
TL;DR: In this paper, the authors focus on the minimum subduction duration and amount of convergence necessary to produce the first-formed blueschist products in evolving, nascent intra-oceanic subduction zones.
Quality Assurance of the Bentonite Material
TL;DR: In this paper, a quality assurance chain for the acquisition of bentonite material for a nuclear waste disposal repository is described, which includes chemical, mineralogical and geotechnical methods.

Depth and seasonal variations in the thermal properties of Antarctic Dry Valley permafrost from temperature time series analysis
TL;DR: In this paper, the thermal properties of perennially frozen, ice-cemented, subsurface Dry Valley permafrost were investigated using thermistor array measurements at 13.5 cm depth intervals and 4-hour time intervals in the top 2 m.

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.
