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 ...

An Overview of the Geomorphological Characteristics of the Pergamon Micro-Region (Bakırçay and Madra River Catchments, Aegean Region, West Turkey)

open access: yesLand, 2021
Current landforms are the basis for understanding past geomorphodynamics and human activities. Based on multiple materials and methods, including geomorphometric analyses of a digital elevation model and visual interpretations of satellite images ...

Estilos geotectónicos bidimensionales y tridimensionales interbloques: Una nueva categoría neotectónica para la determinación de morfoestructuras montañosas

open access: yesInvestigaciones Geográficas, 1994
Cuban Archipelago geologic evolution reveals a W to E migration in Early Mezo–Cenozoic vulcanism and magmatism as well as an increased activity in neotectonics, seismicity, and recent secular endodynamics originating a conspicuous geomorphological ...

The Volcano-Tectonics of the Northern Sector of Ischia Island Caldera (Southern Italy): Resurgence, Subsidence and Earthquakes

open access: yesFrontiers in Earth Science, 2022
The island of Ischia, an active volcanic field emerging in the western sector of the Gulf of Naples (Southern Italy), represents an archetypal case of caldera that underwent a very large resurgence related to the intrusion of a shallow magma body.

Tectonic geomorphology of the Kemalpaşa Basin and surrounding horsts, southwestern part of the Gediz Graben, Western Anatolia [PDF]

open access: yesGeodinamica Acta, 2017
The Kemalpaşa Basin is one of the Quaternary basins in Western Anatolia and represents the south-western branch of the Gediz Graben system in this extensional province. This basin has been formed under the NNE–SSW trending extensional tectonic regime.

The pre-Sinian rift in central Sichuan Basin and its control on hydrocarbon accumulation in the overlying strata

open access: yesPetroleum Exploration and Development, 2018
Based on the latest seismic data, resistivity profile, outcrop evidence and logging data, the structural features of basement in Sichuan Basin and its control on the hydrocarbon accumulation in the Sinian-Cambrian strata was discussed.

Surface Displacements Mechanism of the Dobi Graben from ASAR Time-Series Analysis of InSAR: Implications for the Tectonic Setting in the Central Afar Depression, Ethiopia

open access: yesRemote Sensing, 2022
The Dobi graben is a Quaternary, NW-trending continental rift found within the East-Central Block (ECB) of the Afar Depression (AD) in Ethiopia. The AD might be the only place where three active rifts meet on land.

Relevant aspects to the recognition of extensional environments in the field

open access: yesBoletín Geológico, 2021
The understanding of each geological-structural aspect in the field is fundamental to be able to reconstruct the geological history of a region and to give a geological meaning to the data acquired in the outcrop.
