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

Numerical modeling of post-collisional carbonated alkaline magmatism: Variscan style Orogeny (the Ivrea Zone as natural laboratory)
TL;DR: In this paper, a coupled 2D petrological-thermomechanical approach is used to geodynamically model the processes that led to the Variscan continental collision and subsequent emplacement of the alkaline pipes with application to craton margin metasomatic events.

Chiara Coletti,Alessandro Borghi,Roberto Cossio,Maria Chiara Dalconi,Giorgia Dalla Santa,Luca Peruzzo,Raffaele Sassi,Arianna Vettorello,Antonio Galgaro +8 more
TL;DR: In this article, the thermal conductivity of seven granitoid rocks belonging to five different lithologies (granodiorite, tonalite, granite, gabbro, and syenite) has been analyzed, as main property which must to be assessed, by comparison between traditional measurement methods and a new analytical approach.

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.
