Abstract. We present three-dimensional (3-D) models that describe the present-day thermal and rheological state of lithosphere greater Kenya rift region aiming at a better understanding evolution, with particular focus on plume–lithosphere interactions. The key methodology applied is 3-D integration diverse geological geophysical observations using gravity modelling. Accordingly, resulting lithospheric-scale density model consistent (i) reviewed descriptions lithological variations in...

Abstract. We introduce a regional 3-D structural model of the Barents Sea and Kara region which is first to combine information on sediments crystalline crust as well configuration lithospheric mantle. Therefore, we have integrated all available geological geophysical data, including interpreted seismic refraction reflection seismological maps previously published models into one consistent model. This resolves four major megasequence boundaries (earliest Eocene, mid-Cretaceous, mid-Jurassic...

Abstract Almost every representative ancient building suffered from a fire during its history. Therefore, several limestones, sandstones, gypsum, granites, tuffs, an orthogneiss and two marbles have been tested to analyse the effect of fire. Thermal expansion measurements up 1000 °C reveal that rock shows specific behaviour. Variations are caused by single crystal thermal properties rock-forming minerals different damage processes. In silicate rocks, intragranular fracturing is predominant...

The southern Central Andes (29°S-39°S) is a key area for understanding the interplay between oceanic plate and continental its resulting surface expressions in subduction zone.  In this area, dip of changes from normal (~30° 33°S 35°S) south to flat (< 5° 29° 33°S) north. This region displays remarkable along- across- strike variations both tectonic seismic deformation patterns. context, relative...

Continental rifting and breakup as well plate convergence collision create specific geophysical configurations with characteristic thermal fields which in turn lead to rheological settings. Three-dimensional data-integrated models demonstrate how of the Earth’s crust uppermost mantle are depending on tectonic setting. While spatial variation conductivities, variable contributions radiogenic heat response crustal thickness composition, average geothermal gradients lithosphere main...

Variations of seismic wave speed, in particular shear-wave velocity (vs), are largely temperature controlled the Earth’s mantle. Seismic tomography models thus provide us with insights into upper mantle variations, rheological configuration deep lithosphere and, thus, zones susceptible to strain localization within tectonic plates. With this contribution, we introduce V2RhoT_gibbs, an open-source Python tool for converting vs from and density a self-consistent thermodynamic...

The Upper Rhine Graben (URG), situated along the border of France and Germany, is part intraplate European Cenozoic Rift System. graben widely recognized for its abundant geothermal resources, making it a key region energy transition initiatives. However, characterization URG’s potential remains poorly constrained due to highly variable hydrothermal conditions large observational gaps. Previous studies on fault criticality have often overlooked role historical plate movements,...

The Canary Islands stand out as a prime region within Spanish territory with significant potential for harnessing high enthalpy geothermal resources due to their active volcanic activity. La Palma, one of the youngest islands in archipelago, has witnessed at least seven eruptions over past 500 years, most recent occurring 2021. Despite these compelling signs, development power plants not been pursued on island, mainly because financial risk involved such project and lack detailed geophysical...

Abstract. The aim of this study is to investigate the shallow thermal field differences for two differently aged passive continental margins by analyzing regional variations in geothermal gradient and exploring controlling factors these variations. Hence, we analyzed previously published 3-D conductive lithospheric-scale models Southwest African Norwegian margins. These differentiate various sedimentary, crustal, mantle units integrate different geophysical data such as seismic observations...

In this study we assess the present-day gas hydrate stability zone for Barents Sea and Kara region. Thereby, make use of a data-based 3D lithosphere-scale pressure thermal model. The resulting varies within >1km across area strongly correlates with local geological settings corresponding geothermal gradient. Gas hydrates containing hydrocarbons from thermogenic source (CH4+C2H3+C3H8) are potentially more widespread than previously assumed. feed may have derived leaking petroleum systems...

Abstract Previous thermomechanical modeling studies indicated that variations in the temperature and strength of crystalline crust might be responsible for juxtaposition domains with thin‐skinned thick‐skinned crustal deformation along strike foreland central Andes. However, there is no evidence supporting this hypothesis from data‐integrative models. We aim to derive density structure lithosphere by means integrated 3‐D modeling, order provide a new basis discussions compositional within...

Abstract The southern S outh A frican continental margin documents a complex system that has undergone both rifting and transform processes in manner its present‐day architecture geodynamic evolution can only be better understood through the application of multidisciplinary multi‐scale geo‐modelling procedure. In this study, we focus on proximal section larger Bredasdorp sub‐basin (the westernmost five offshore M esozoic sub‐basins), which is hereto referred as W estern B redasdorp asin....

Abstract Significant lateral variations in observed temperatures the B eaufort‐ M ackenzie asin raise question on temperature‐controlling factors. Based structural configuration of sediments and underlying crust area, we calculate steady‐state 3D conductive thermal field. Integrated data include base relic permafrost layer representing 0 °C‐isotherm, public‐domain temperature (from 227 wells) conductivity data. For >75% wells predicted deviate by <10 K from temperatures, which...
