The objective of this study was to obtain the deep subsurface structure a saline-evaporitic formation affected by an anticlinal structure, defining position and thickness for its future exploitation (potassium salts). To improve knowledge, geophysical methods can be applied establish detailed information on geological structures at depth. This work analyzes results time domain electromagnetic (...

Heterogeneities in the magnetic signature along intraplate shear zones complicate their correlation with physical processes that are involved geodynamic evolution of megathrusts. Isolating preferred orientation different minerals may provide insights into faulting processes, tectonics, and strain partitioning. Studies exhumed analogs fundamental to constrain variations properties respect a cont...

Structurally controlled bathymetry in rifts has a significant influence on sediment routing pathways and depositional architecture of gravity flow deposits. In contrast to rift segments characterized by crustal-scale half-grabens, the tectono-stratigraphic evolution deep-water domains characterised distributed faulting narrow fault terraces received little attention. We use 3D broadband seismic...

Scandium is an important industrial metal for which demand projected to increase in the future. Although many Sc deposits are secondary, scavenged by clinopyroxene during fractional crystallization of primary, mafic-ultramafic magmas. may thus occur sub-economic concentrations intrusions. In this work, we present new data on concentration Bushveld Complex (BC) South Africa. The eastern and west...

Two large-scale north-dipping, low-angle normal faults cut the Everest massif at the top of the High Himalayan slab in Nepal. The upper fault the Qomolangma Detachment, follows the north slope of Everest from above the ‘Yellow Band’ at c. 8500 m on the Southwest Face down to the Rongbuk glacier. On the south side of Everest this fault places unmetamorphosed Ordovician mudstones and limestones a...

A sedimentological, biostratigraphic, and petrographical investigation was conducted on exposed sedimentary rocks in the Seulimeum Formation Northwest Aceh Basin, Sumatra. Sedimentary facies analysis suggests a deep-marine depositional environment consists of an inner fan, middle outer fan to basin plain deposits. New foraminiferal data designated late Miocene early Pleistocene age for studied ...

Fold-and-thrust belts have a high variability of structural styles, whose investigation provides continuous updates the predictive models that try to better approximate geometries recognized in field. The majority studies are focused on geometry and development folds thrust surfaces amount displacement, taking into account role played by involved stratigraphic succession assumed as layer cake. ...

Abstract We study how the asymmetric geometry of thrust faults affects dynamics supershear ruptures and their associated trailing Rayleigh as they interact with free surface, investigate resulting near‐field ground motions. Earthquakes are mimicked by propagating laboratory along a frictional interface 61° dip angle. Using an experimental technique that combines ultrahigh‐speed photography digi...

We apply a deep learning model to segment and identify rock characteristics based on Structure-from-Motion orthomap digital elevation of rocky fault scarp in the Volcanic Tablelands, Eastern California, USA. By post-processing results, we build semantic map analyse trait distributions. The resulting contains nearly 230 000 rocks with effective diameters ranging from 2 250 cm. Rock distributions...

The Merensky Reef hosts one of the largest PGE resources globally. It has been exploited for nearly 100?years, yet its origin remains unresolved. In present study, we characterised eight samples reef at four localities in western Bushveld Complex using micro-X-ray fluorescence and field emission scanning electron microscopy. Our results indicate that formed through a range diverse processes. Te...
