Confronting Solid‐State Shear Bias: Magmatic Fabric Contribution to Crustal Seismic Anisotropy

Geophysical Research Letters, 2023
Seismic anisotropy is controlled by aligned rock‐forming minerals, which most studies attribute to solid‐state shear with less consideration for magmatic fabric in plutonic rocks (rigid‐body rotation of crystals in the presence of melt).

Tectonic Inheritance During Plate Boundary Evolution in Southern California Constrained From Seismic Anisotropy

Geochemistry, Geophysics, Geosystems, 2021
The style of convective force transmission to plates and strain‐localization within and underneath plate boundaries remain debated. To address some of the related issues, we analyze a range of deformation indicators in southern California from the ...

THE MIOCENE AND DEVONIAN MAGMATISM AT THE JUNCTION BETWEEN THE TUVA-MONGOLIAN MASSIF AND SIBERIAN CRATON: COMMON COMPONENT OF MANTLE SOURCES AND ITS ORIGIN

Геодинамика и тектонофизика, 2015
Devonian dikes of the Urik-Belaya and Shagayte-Gol-Urik zones and Miocene lavas of the Urik volcanic field are spatially associated with each other at the structural junction between the Neoproterozoic Tuva-Mongolian massif and Siberian craton.

HIGH-MG LAVAS FROM THE DARIGANGA VOLCANIC FIELD IN THE SOUTHEASTERN MONGOLIA: PETROGENETIC MODEL OF MAGMATISM AT THE ASTHENOSPHERE–LITHOSPHERE BOUNDARY

Геодинамика и тектонофизика, 2015
It is revealed that high-Mg lavas (MgO=11.0–15.8 wt. %) are spatially controlled by linear zones extending for more than 90 km and demonstrate chemically distinct differences from moderately-Mg compositions (MgO=3.0–11.0 wt.

METAMORPHIC CORE COMPLEXES OF THE TRANSBAIKALIA: REVIEW

Геодинамика и тектонофизика, 2015
Metamorphic core complexes (hereafter MCC) revealed in the Transbaikalia have similar features of their patterns. Three levels can be distinguished by structural­material indicators: core, zone of mylonites (dynamically metamorphosed rocks) and overlying
