PALEOPROTEROZOIC TECTONICS AND EVOLUTIONARY MODEL OF THE ONEGA SYNCLINORIUM
Геодинамика и тектонофизика, 2023 Consideration is being given to the Onega Paleoproterozoic structure (Onega synclinorium, OS) as a tectonotype of intraplate negative structures, which experience intermittent subsidence over a long period of time.

Evidence from Rb–Sr mineral ages for multiple orogenic events in the Caledonides of Shetland, Scotland [PDF]
, 2015 Shetland occupies a unique central location within the North Atlantic Caledonides. Thirty-three new high-precision Rb–Sr mineral ages indicate a polyorogenic history.

Microstructures of the Lim zone along the contact with Dinaridic Ophiolite nappe [PDF]
Geološki Anali Balkanskoga Poluostrva, 2007 The Lim Zone is a part of the low-grade metamorphic core complex called the Lim Palaeozoic Unit, overlain by detached Triassic sedimentary successions. The Lim Unit is located in the footwall of overriding Dinaridic Ophiolite nappe.

The role of strain localization in magma injection into a transtensional shear zone (Variscan belt, SW Iberia). [PDF]
, 2013 This study deals with the interaction between deformation and magmatism in mid- to deep-crustal domains. The relation is analysed between migmatites and shear zones and the spatial distribution of leucogranitoid veins and dykes running through a footwall

The Role of the Magnetorotational Instability in the Sun [PDF]
, 2014 We calculate growth rates for nonaxisymmetric instabilities including the magnetorotational instability (MRI) throughout the Sun. We first derive a dispersion relation for nonaxisymmetric instability including the effects of shear, convective buoyancy ...

Microstructure of shear zones in Fontainebleau sandstone [PDF]
International Journal of Rock Mechanics and Mining Sciences, 2002 On the basis of image analysis, porosity and grain-size changes have been studied inside the shear bands formed in triaxial testing on a Fontainebleau sandstone. For this rock the shear band is characterized by a white coloration visible to the naked eye.

The impact of magnetic shear on the dynamics of a seeded 3D filament in slab geometry
Nuclear Materials and Energy, 2017 Seeded filament simulations are used to study blob dynamics with the state-of-the-art TOKAM3X fluid code in the scrape-off layer (SOL) using a slab geometry.

Strain Localization: Analog Modeling and Anisotropy of Magnetic Susceptibility
Geochemistry, Geophysics, Geosystems, 2023 The majority of the strain in Earth crust and upper mantle is localized to the high strain zones developed at ductile‐to‐brittle condition at kilometer‐to‐micrometer scale.
