Strain Analysis and Kinematics of Deformation of the Tectonic Nappe Pile in Olympos-Ossa Mountainous Area: Implication for the Exhumation History of the HP/LT Ampelakia Unit and the Olympos-Ossa Tectonic Window (Eastern Thessaly, Central Greece)

Geosciences
This paper focuses on the structural and finite strain analysis of the Pelagonian nappe, the HP/LT Ampelakia unit, and the Olympos-Ossa unit in the Olympos-Ossa mountainous area in order to better understand the exhumation history of the Ampelakia unit ...

Metamorphic Reactivity Influences Amphibole Creep Behaviour

Journal of Metamorphic Geology, EarlyView.
ABSTRACT The rheological behaviour of solid‐solution minerals may play an important role in determining how metamorphic crust accommodates deformation. Whether or not a mineral's deformation is diffusion or dislocation‐mediated depends on a range of extrinsic variables such as stress, strain rate and temperature, as well as intrinsic variables such as ...

Spatial and temporal evolution of a coastal erg margin: the Middle Jurassic Page Sandstone, southern Utah, USA

Sedimentology, EarlyView.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Hydraulic analysis of a compound weir (triangular-rectangular) simulated with computational fluid dynamics (CFD)

Tecnología y ciencias del agua, 2021
To make an efficient delivery of water to irrigation users, it is necessary to have accurate dispositive to measure flow rates. These dispositive include triangular and rectangular weirs for measured flow rates ranges between 30 and 200 l s-1.

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

Geological Journal, Volume 61, Issue 8, Page 2258-2278, August 2026.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.

Long‐Distance Aeolian Dust Deposited on the Island of Crete (Greece): Detection, Characterization, and Provenance

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Long‐distance aeolian dust transport represents one of the largest sediment fluxes on Earth, with North Africa being a dominant source. The island of Crete in the Eastern Mediterranean lies within major transport pathways but remains underexplored regarding multi‐proxy fingerprinting of deposited dust.
