Tectonic and petrogenetic evolution of sub-horizontal granulite-grade fabric in lower continental crust: Constraints on lower crustal flow from the western Canadian Shield
Crustal flow orogeny the andes the Himalayas the earth's crust granulite

Ductile, weak flow of continental lower crust is inferred for a number of orogenic systems, including the Andes and the Himalayan-Tibetan system. Sub-horizontal, high-temperature fabrics in rare expos...
Analysis of the Gouldsboro Pluton and the Fehr Granite: Understanding the Scales of Magmatic Processes and Partial Melt Generation from the Deep to Shallow Crust

The heterogeneity of the continental crust has a first order control on the dynamics of plate tectonic processes and the compositions of the Earth in both time and space. Heterogeneity can be characte...
With the help of a tiny fragment of zircon extracted from a remote rock outcrop in Australia, the picture of how the planet became habitable to life about 4.4 billion years agcrust o is coming into sh...
Regional Flow in the Lower Crust and Upper Mantle under the Southeastern Tibetan Plateau
Regional Flow Channel Flow Crustal Deformation Deep and Large Suture

Seismic tomography reveals an “R-shape” regional flow constrained between the depths of 50 to 80 km in the Southeastern Tibetan Plateau (STP) which demonstrates some of the differences revealed by the...
Neutron flux variations near the Earth’s crust. A possible tectonic activity detection
Neutron flux variations the Earth’s crust A possible tectonic activity detection
2009/12/10
The present work contains some results of observations of neutron flux variations near the Earth’s surface. The Earth’s crust is determined to be a significant source of thermal and slow neutrons, ori...
Inhomogeneous deformation in deeply buried continental crust,an example from the eclogite-facies province of the Western Gneiss Region,Norway

Mesoproterozoic protoliths and Scandian eclogites with coronitic textures were preserved in low-strain domains during burial and exhumation in the Sunnfjord Region of western Norway. In domains with m...
Pre-earthquake signals–Part II:Flow of battery currents in the crust
Pre-earthquake signals Flow of battery currents crust
2009/12/30
When rocks are subjected to stress, dormant electronic charge carriers are activated. They turn the stressed rock volume into a battery, from where currents can flow out. The charge carriers are elect...
