New insights into structural and tectonic evolution of Safaga-Semna shear belt, Eastern Desert, Egypt: advanced integration of aeromagnetic, remote sensing and field studies

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
Shear zones play an essential role in controlling the distribution of ore resources, including Au and associated mineral deposits. Our study integrates aeromagnetic, structural, and remote sensing (RS) data to analyze the geodynamics, tectonics, and ...

Rapid Incorporation of Metasediments Into Lower Crust of the Gangdese Magmatic Arc, Southern Tibet

Geochemistry, Geophysics, Geosystems
Deeply exhumed crustal terranes of continental arcs worldwide commonly contain metasedimentary components, but the nature of these lithologies and how they became incorporated into the lower crust are not fully understood.

Block‐in‐Matrix Deformation and Veining in Alpine Subducted Oceanic Metasediments at Blueschist Facies Conditions

Geochemistry, Geophysics, Geosystems
In subduction zones, the locked seismogenic zone is bordered by an upper and a lower transition zone. In these transition zones, deformation is primarily accommodated by an interplay of diffuse viscous deformation within a weak matrix and brittle ...
