Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

Geological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Plastic luminescence in mechanoluminescent composites

InfoMat, EarlyView.
Through compression tests and numerical simulations, this study demonstrates that the luminescence of a mechanoluminescent (ML) composite is strongly associated with plastic strain, thereby providing new insight into deformation‐induced luminescence during the plastic stage.

Stability analysis of cemented soil slopes in a geotechnical centrifuge [PDF]

, 2022
Geotechnical centrifuge technology is a strong and successful method for physical modeling of slopes. It provides the benefit of studying the slopes' failure mechanisms. In this research, slope models of cemented and non-cemented soils were tested in a

New constraints on the postglacial evolution of Lago Maggiore, Northern Italy

Journal of Quaternary Science, EarlyView.
ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core

Design and performance of a geotechnical centrifuge cooling system based on a raft foundation heat exchanger

Shenzhen Daxue xuebao. Ligong ban
During operation, a geotechnical centrifuge generates substantial heat that must be effectively dissipated by a dedicated cooling system. To make full use of shallow geothermal energy and to investigate the heat transfer performance of a raft foundation ...

Rearrangement Towards Stability: Plastic Shakedown in Granular Materials Under Thermal Cycles

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Granular materials are routinely subjected to thermal cycling due to natural and anthropogenic phenomena. Despite the ubiquity of this occurrence and its relevance for science, engineering, and technology, the long‐term thermo‐mechanical response of granular materials to repeated heating and cooling remains poorly understood.

An Open Database of Lunar Regolith and Simulants Properties

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Lunar regolith, the layer of unconsolidated material covering the Moon's surface, is central to the science and technology developed for the Moon, notably related to in‐situ science investigations, resource utilization, surface infrastructure, and mobility systems.

Particle‐Scale Mechanics of a Regolith‐Type Soil

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The existing studies have reported that the surface of Mars shows the presence of materials having igneous origin, including basalt and regolith‐type coarse soils. These findings are affected by significant uncertainties and, therefore, the selection of simulants for various exploration applications, including surface mobility of rovers ...

An Elasto–Plastic Hydro–Mechanical Model for Analyzing the Swelling Behavior of Heterogeneous Clay–Sulfate Rocks

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.
