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

What classic greywacke (litharenite) can reveal about feldspar diagenesis: An example from Permian Rotliegend sandstone in Hessen, Germany
TL;DR: Rotliegend siliciclastic sediments in southern Hessen (Germany) are a good example of dissolution of detrital feldspars, which is a common feature in many sandstones as mentioned in this paper.

Numerical simulations of convection in crystal‐bearing magmas: A case study of the magmatic system at Erebus, Antarctica

TL;DR: In this paper, the effects of crystals on convection while changing conduit size and the system boundaries from closed to open were investigated using a bi-phase (melt and crystals), fluid dynamical model, in an idealized 2D geometry representing a lava lake cooled from above and a reservoir heated from below.

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.
