Probe Embryonic Damage Evolution in Bulk Metallic Glasses under Plate-impact Loading

EPJ Web of Conferences, 2018
Microdamage in very short stress durations of spallation process in Zr-based bulk metallic glass (Zr-BMG) samples were captured by a specially designed plate impact technique.

Dating the Orosirian orogen-parallel shear zones in the western Khondalite Belt, North China Craton: new constraints from monazite, titanite and apatite U-Pb ages

Frontiers in Earth Science
A series of NE-to E-trending ductile shear zones are widely distributed in the Khondalite Belt, a Paleoproterozoic collisional orogen in the North China Craton.

Fast ductile failure of passive margins from sediment loading

Geophysical Research Letters, 2000
Sediment loading at continental margins has been interpreted as a very inefficient mechanism for initiating subduction. We have re‐investigated this problem using a time‐dependent, non‐linear ductile failure analysis in which the effects of power‐law ...

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.

The structural history and mineralization controls of the world-class Geita Hill gold deposit, Geita Greenstone Belt, Tanzania [PDF]

, 2016
The Geita Hill gold deposit is located in the Archean Geita Greenstone Belt and is one of the largest gold deposits in East Africa. The Geita Greenstone Belt experienced a complex deformation and intrusive history that is well illustrated and preserved ...

Petrographic, structural, and deformational analysis in the Curitiba Shear Zone, Ribeira Belt: a case study at São Jorge quarry, Eastern Paraná State, Brazil [PDF]

Brazilian Journal of Geology
The Ribeira Belt in southern Brazil records the Neoproterozoic tectonic evolution associated with the amalgamation of Western Gondwana, and its shear zones provide critical constraints on transcurrent–transpressive deformation regimes.

Cyclic Brittle‐Ductile Oscillations Recorded in Exhumed High‐Pressure Continental Units: A Record of Deep Episodic Tremor and Slow Slip Events in the Northern Apennines

Geochemistry, Geophysics, Geosystems, 2021
The geological record of deep fossil seismogenesis in subduction zones is limited due to common rock overprinting during exhumation and only a few regions expose well‐preserved deeply exhumed structures.

Zircon dissolution in a ductile shear zone, Monte Rosa granite gneiss, northern Italy [PDF]

, 2008
The sizes, distributions and shapes of zircon grains within variably deformed granite gneiss from the western Alps have been studied. Zircon shows numerous indicators of a metamorphic response in both the host gneiss and a 5 cm wide continuous ductile ...

Fault textures in volcanic conduits: evidence for seismic trigger mechanisms during silicic eruptions. [PDF]

, 2005
It is proposed that fault textures in two dissected rhyolitic conduits in Iceland preserve evidence for shallow seismogenic faulting within rising magma during the emplacement of highly viscous lava flows. Detailed field and petrographic analysis of such
