Advective Heat Transport and the Salt Chimney Effect: A Numerical Analysis

open access: yesGeofluids, 2018
We conducted numerical simulations of coupled fluid and heat transport in an offshore, buried salt diapir environment to determine the effects of advective heat transport and its relation to the so-called “salt chimney effect.” Model sets were designed ...

Distinguishing the effect of diapir growth on magnetic fabrics of syn-diapiric overburden rocks: Basque-Cantabrian basin, Northern Spain [PDF]

open access: yes, 2017
An analysis of Anisotropy of Magnetic Susceptibility was done on Aptian–Albian sediments from the Basque–Cantabrian basin. Samples were collected from 39 sites in the halokinetic sequences of the Bakio, Bermeo, Guernica and Mungia diapirs; 28 sites were ...

Evaporite-karst processes, landforms, and environmental problems [PDF]

open access: yes, 2008
Evaporite karst is widespread, but relatively unknown when compared with carbonate karst; this special issue addresses that lack of familiarity. Evaporite rocks have much higher solubilities and faster dissolution rates than carbonate rocks and they also

Quantifying Diapir Ascent Velocities in Power‐Law Viscous Rock Under Far‐Field Stress: Integrating Analytical Estimates, 3D Numerical Calculations and Geodynamic Applications

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Diapirism is crucial for heat and mass transfer in many geodynamic processes. Understanding diapir ascent velocity is vital for assessing its significance in various geodynamic settings.

Magma ascent mechanisms in the transition regime from solitary porosity waves to diapirism [PDF]

open access: yesSolid Earth, 2021
In partially molten regions inside the Earth, melt buoyancy may trigger upwelling of both solid and fluid phases, i.e., diapirism. If the melt is allowed to move separately with respect to the matrix, melt perturbations may evolve into solitary porosity ...

The large-scale surface uplift in the Altiplano-Puna region of Bolivia: A parametric study of source characteristics and crustal rheology using finite element analysis [PDF]

open access: yes, 2013
This paper focuses on the driving mechanism behind a 70 km wide region of ground uplift centered on Uturuncu volcano, in the Altiplano-Puna region of southern Bolivia.

NEW INFORMATION TECHNOLOGY AND ITS CAPACITIES FOR MODELING OF GEOSYSTEMS

open access: yesГеодинамика и тектонофизика, 2015
Numerical solution of the Navier-Stokes equations for free and forced convection in solid and porous media is challenging as an evolution equation for pressure is lacking. An information technology is proposed on the basis of a new system of hydrodynamic

Geology of the Salinas De Rosío Diapir (Basque-Cantabrian Basin, Spain)

open access: yesJournal of Maps
This study presents a new geological map of the Salinas de Rosío diapir (Basque-Cantabrian Basin, northern Spain), based on detailed fieldwork, interpretation of high-resolution topographic data, and integration of existing geological information.

Tectonic setting and evolution of the Morin anorthosite, Grenville province, Quebec [PDF]

open access: yesBulletin of the Geological Society of Finland, 1970
The Morin Anorthosite Mass underlies an area of 2 500 square kilometers; it consists of three tectonic units: a dome, a diapir and a nappe. The units have in common a large part of their magmatic history, but their tectonic evolution is different.

Rising and falling diapirs, shifting depocenters and flap overturning in the Cretaceous Sopeira and Sant Gervàs subbasins (Ribagorça basin, Southern Pyrenees) [PDF]

open access: yes, 2016
The halokinetic structure of inverted salt-related continental margins is frequently obliterated by compressional overprinting. The Cretaceous Sopeira and Sant Gervàs subbasins of the Ribagorça basin (South-Central Pyrenees) show evidence of salt-related
