The Geotechnical Design Reliability of Offshore Wind Monopiles
Offshore wind energy is expected to become one of the major clean energy sources to combat climate change. Monopile foundations play a central role in shallow water offshore wind development. The design of the monopile is gradually matured but the long-term reliability level of monopile foundations…

Dual-Peak Dispersion and Attenuation of Compressional Waves from Coupled Thermo-Viscoelastic Mechanisms
Lord–Shulman (LS) thermoelasticity theory is integrated with the Kelvin–Voigt (KV) viscoelastic model to develop a coupled thermo-viscoelasticity formulation predicting two compressional waves, an elastic wave (E-wave), a thermal wave (T-wave), and a shear wave (S-wave), all with wave-diffusion…

Post-Laramide Extension and Erosion in the Madison and Gallatin Ranges of Southwest Montana from Apatite (U-Th-Sm)/He Thermochronometry
Since the end of the Laramide Orogeny (~50 Ma), southwest Montana has experienced complex tectonic, climatic, volcanic, and mantle dynamic processes that have left an imprint on the landscape. Here, we examine the impact of post-orogenic and recent hotspot-related processes on the landscape by…

Petrogenesis and Tectonic Evolution of Neoproterozoic Volcanic Rocks from Um Khariga, Egyptian Nubian Shield: Implications for Early Crustal Growth Stage
The Neoproterozoic Arabian-Nubian Shield (ANS) contains one of the most extensive exposures of juvenile continental crust on Earth, with the Egyptian segment, the Nubian Shield (ENS), representing a critical component of this shield. Within the ENS, the Um Khariga volcanic province represents one…

Structure of the Blue Ridge to Great Valley Transition in Northern Virginia, USA. Evidence for Late Alleghanian Brittle Out-of-Sequence Thrusting in the Central Appalachians
Out-of-sequence thrust faults develop in the hangingwall of a preexisting thrust and provide a mechanism for internal thickening of a developing thrust wedge and thereby contribute to the propagation of the fold-and-thrust belt by maintaining its critical taper. In the central Appalachians, a late…

Cambrian Carbon-Sequestration Geosystems of Canada
Skepticism of carbon capture and storage’s (CCS) potential for curbing anthropogenic global warming continues. That doubt is fed, in part, by the failure of some CCS sites to meet injection targets because of problems with the subsurface geology. This paper argues that more rigorous geoscience…

Study on Proppant Transport among the Perforations within a Cluster and Accumulation in Inclined Wellbores Considering Turbulence Effect
During hydraulic fracturing, the uniform distribution of proppant among perforations is crucial for enhancing reservoir permeability. However, problems such as uneven proppant distribution between perforations and accumulation-induced blockage often occur. Current research focuses on proppant…

Fault Structure, Deformation Mechanisms, and Why Fault Zones Matter to Society
Faults are widespread geologic structures that form in sediment and all rock types, occur in all tectonic regimes, and can be a blessing or a curse to society. Faults and fault zones act as conduits for underground movement of water and as plumbing systems for aquifers and springs essential for…

Correlation between the Yarlung Tsangpo River and the Loess Landscape in the Eastern Himalayan Syntaxis
Thick loess deposits occur in the Linzhi region along the Niyang River, a tributary of the Yarlung Tsangpo River, within the tectonically active Eastern Himalayan Syntaxis. Despite rapid surface uplift and frequent high-magnitude erosion, loess persists in this dynamic environment. Using remote…

Fault Zone Control on Rapid Groundwater Flow in Cretaceous Carbonates of the Hidden Valley Fault Zone, Texas
Understanding geological controls on subsurface fluid flow is critical for groundwater resource management and aquifer protection and is particularly challenging in faulted carbonate aquifers due to dissolution and conduit development. We conducted an integrated hydrologic study of the Hidden…

Distribution of Strike-Slip Displacement in the Middle and Southern Segments of the Daliangshan Fault Zone and Its Implication for Fault Rupturing Behavior
The Daliangshan Fault Zone is an important branch fault of the Xianshuihe-Xiaojiang Fault System, which is the eastern boundary of the Sichuan-Yunnan Rhombic Block. It plays a great role in understanding the tectonic activity in the southeast margin of the Qinghai-Tibet Plateau. In this paper…

Chemical Weathering Effects on the Dynamic Mechanical Properties of Black Shale Slip Zone under Acid Erosion Action
Water-rock interaction and intense chemical weathering often lead to stiffness reduction of the slip zone inside the rock slope, which plays a significant role in the evolution of slip zone, especially for the clay-type rock in acidic environment. This study aims to estimate the evolution of…

Out-of-Sequence Thrusting at Orogenic Scale: Assembly of Allochthons along the Western Flank of the Southernmost Appalachian Orogen, USA
Foreland fold-and-thrust belt models have historically focused on the development of thrust sheets that progressively propagate from the hinterland to the foreland (in-sequence [IS]) due to a critically tapered orogenic wedge. In this classic orogenic model, tectonic stresses, initially…
