Assessing the suitable electrical resistivity arrays for characterization of basement aquifers using numerical modeling [PDF]

open access: yesHeliyon, 2022
Numerical modeling analysis was used to assess the suitable electrical resistivity arrays for the characterization of geological structures, including dyke, horst, graben, sub-vertical, and vertical structures. These geological structures usually make up

A model for the horst and graben structure of Midocean ridge crests based upon spreading velocity and basalt delivery to the Oceanic crust [PDF]

open access: yesGeofísica Internacional, 1974
La cresta de la dorsal del Pacifico oriental entre los 17° N a los 40° S se caracteriza por un horst central. Este rasgo se atribuye a! producto estacionario de una deriva constante en torno a la cresta, en que la varianza de la velocidad de inyección es

New Particle‐Wise Finite Element Strain Analysis for Discrete Displacement of Fold‐And‐Thrust Belt and Horst‐And‐Graben Models

open access: yesEarth and Space Science, 2023
The granular behaviors of shallow Earth materials are associated with brittle deformations and mass transport along the surface and fault zones. Green strain has been adopted to quantitatively analyze the fold‐and‐thrust belt and horst‐and‐graben ...

Integrated mechanical environment of pre- and post-rupture fault and asperity origin of the 2011 giant Tohoku-Oki earthquake [PDF]

open access: yesScientific Reports, 2022
It is a key to know mechanical environment (ME) of pre- and post-rupture fault of giant earthquakes at subduction zones for predicting earthquake and tsunami disaster. However, we know little about its details till now.

Control of 3-D tectonic inheritance on fold-and-thrust belts: insights from 3-D numerical models and application to the Helvetic nappe system [PDF]

open access: yesSolid Earth, 2020
We apply three-dimensional (3-D) thermo-mechanical numerical simulations of the shortening of the upper crustal region of a passive margin in order to investigate the control of 3-D laterally variable inherited structures on fold-and-thrust belt ...

Some thoughts on the morphotectonic development of the Denizli region Basic

open access: yesBulletin of the Mineral Research and Exploration, 2022
The Denizli region is located to the east of the Buldan Horst. Although they follow the same trends as the Büyük Menderes and Gediz Grabens, the Denizli region has undergone semi-independent evolution during the Quaternary.

Study of the sub-surface geological condition of the Sibalaya flow liquefaction using seismic refraction method [PDF]

open access: yesE3S Web of Conferences, 2023
Understanding the occurrence of flow liquefaction requires knowledge of the sub-surface condition controlling its occurrence. This paper presents the results of seismic refraction surveys conducted to evaluate the sub-surface geological condition in the ...

Extension and inversion of salt-bearing rift systems [PDF]

open access: yesSolid Earth, 2020
We used physical models to investigate the structural evolution of segmented extensional rifts containing syn-rift evaporites and their subsequent inversion. An early stage of extension generated structural topography consisting of a series of en-échelon

From shallow-water carbonate ramp to hemipelagic deep-marine carbonate deposition: Part 1. General characteristics, microfacies and depositional history of the Middle to Late Anisian Bulog sedimentary succession in the Inner Dinarides (SW Serbia) [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2023
The opening of the Neo‐Tethys started in the Middle Anisian and is recorded in the drowning succession of the shallow‐water Ravni/Steinalm Carbonate Ramp and the subsequent deposition of deep‐marine limestones, e.g., the red nodular limestones of the ...
