New Insights Into Active Tectonics and Landscape Evolution of the Northernmost Chilean Central Depression

Tectonics, Volume 44, Issue 1, January 2025.
Abstract Active deformation and landscape evolution in North Chilean forearc involve multiscale tectonic processes, such as crustal thickening causing orogenic‐scale uplift and faulting modulating the mountain‐front landscape. In the Central Depression, faults redirecting Quaternary drainages are poorly understood due to their subtle surface ...

Jovan Cvijic: Forefather of neotectonics [PDF]

Zbornik Radova: Geografski institut "Jovan Cvijić", 2003
Neotectonic activity as crucial factor of geomorphological evolution represents nowadays widely reckognized fact. It is generaly believed and accepted that the study of neotectonics began during first half of the 20th century by Russian scientists in the

Present‐Day Shortening Accommodated by Folding, Thrusting and Strike‐Slip Faulting in the Enriquillo Basin of Southern Central Hispaniola: Implications for the Regional Seismic Hazard

Tectonics, Volume 44, Issue 1, January 2025.
Abstract Hispaniola accommodates a significant portion of the present‐day convergence between Caribbean and North American plates. Located in southern Hispaniola, the Neogene Enriquillo basin is bounded by the Neiba and Bahoruco mountain ranges. The role of active individual faults and fault systems in this basin is not well understood, particularly ...

Morphosedimentary Response of Rivers Crossing Multiple Fault‐Controlled Subsiding Areas: Field Evidence and Laboratory Experiments

Basin Research, Volume 37, Issue 1, January–February 2025.
ABSTRACT Downstream changes of fluvial styles and related grain size triggered by localised tectonically‐induced changes in riverbed gradient are still poorly understood, especially in terms of their impact on the accumulation of alluvial successions. In this study, we analyse the morpho‐sedimentary response of rivers crossing multiple fault‐controlled

Deformation Characteristics and Control Measures for Deep Foundation Pit in Soil–Rock Composite Strata in the Guangzhou Area

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Geological conditions and supporting structures are critical factors influencing the deformation characteristics of deep excavations. This study investigates the deformation characteristics and corresponding control measures for typical deep excavations, focusing on a metro station excavation within a mixed soil–rock stratum in Guangzhou.

Joint orientation measurements in Western Alberta and British Columbia

Annals of Geophysics, 1981
Joint orientations were measured in the mountains of Western Alberta<br />and British Columbia. These were then evaluated statistically according<br />to the standard method of Kohlbeck and Scheidegger.

Gravity field and geothermal structure of the Corsica‐Sardinia Block

Terra Nova, Volume 36, Issue 6, Page 506-515, December 2024.
Abstract This paper presents a finite‐differences 3D numerical model that simulates the gravity and thermal structure of the Corsica‐Sardinia Block (CSB), an apparently stable lithospheric domain characterized by cryptic tectonic activity. In the experiments, we change the density and heat production rate of the model crust within a range of ...

Shallow Lake, Strong Shake: Record of Seismically Triggered Lacustrine Sedimentation From the 1959 M7.3 Hebgen Lake Earthquake Within Henrys Lake, Idaho

Geophysical Research Letters, Volume 51, Issue 22, 28 November 2024.
Abstract We investigate a shallow lake basin for evidence of a large historic intraplate earthquake in western North America. Henrys Lake, Idaho is an atypical candidate for lacustrine paleoseismic study given its shallow depth (∼7 m) and low relief (≤2° slopes).

3‐D Subsurface Geophysical Modeling of the Charity Shoal Structure: A Probable Late Proterozoic‐Early Paleozoic Simple Impact Structure in Eastern Lake Ontario

Earth and Space Science, Volume 11, Issue 11, November 2024.
Abstract The Charity Shoal structure is a circular, ∼1.2‐km‐diameter, bedrock‐rimmed shoal in eastern Lake Ontario with a ∼20‐m‐deep central basin. The structure has been proposed as a possible Middle Ordovician impact crater or volcanic intrusion. We conducted marine seismic and magnetic surveys (9‐km2) and 3‐D geophysical modeling to better resolve ...
