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

Conduction Plus Convection Heat Flow Modeling for the Linga Complex, Peruvian Coastal Batholith
TL;DR: Oxygen and hydrogen isotope values obtained from 64 minerals separated from 18 samples were employed to determine the source of magma and hydrothermal fluids that caused potassic, propylitic, phyllic, and argillic alteration in the Linga complex, situated in the mid-to-late Cretaceous Peruvian Coastal Batholith near Ica as mentioned in this paper.

A composite sphere assemblage model for porous oolitic rocks: Application to thermal conductivity
TL;DR: In this article, a two-step homogenization method was proposed to determine linear effective thermal conductivity of porous rocks characterized by an assemblage of grains (oolites) coated by a matrix.

Numerical Geodynamic Modeling of Continental Convergent Margins
TL;DR: Li et al. as mentioned in this paper proposed a model for the exhumation of high pressure to ultra-high pressure (HP-UHP) metamorphic rocks, which is one of the most provocative findings in the Earth sciences.

Novel use of the enhanced thermal response test in crystalline bedrock
TL;DR: In this article, the authors used the Enhanced Thermal Response Test (ETRT) to determine the thermophysical properties of bedrock, including thermal conductivity, natural convection, and drill hole thermal resistance as a function of depth in crystalline bedrock.

Thermorheological model for the European Central Alps: brittle–ductile transition and lithospheric strength
Alfio Viganò,Silvana Martin +1 more
TL;DR: In this article, a two-dimensional thermorheological model of the Central Alps along a north-south transect is presented, where temperature distribution matches surface heat flow and results in Moho temperatures between 500 and 800°C.

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.
