Lithospheric deformation on Earth is localized under both brittle and ductile deformation conditions. As high-temperature ductile rheologies are fundamentally strain-rate hardening, the formation of localized ductile shear zones must involve a structural or ...

This paper first presents Sm-Nd geochronology that dates garnet growth in quartzofeldspathic gneisses. Second, modeling of compositional zoning in garnet is used to constrain the pressures and temperatures of garnet growth. This paper finally discusses how ...

<p>The timescale for the generation of granitic magmas and their subsequent intrusion, crystallization, and cooling as plutons is no longer incompatible with the biblical time frames of the global, year-long Flood cataclysm and of 6,000-7,000 years for earth ...

In this study the east and west rupture directions of the 1943 and 1944 earthquakes on the North AnatolianFault (NAF) are hypothesized to represent, respectively, long term preferred propagation directions on the corresponding sections of the NAF. To test ...

In this paper it has been studied the Precambrian mafic dykes to understand their nature, geochemical characteristics and their genesis.

This paper shows that continental aggregation promotes large-scale melting without requiring the involvement of plumes.

This paper presents a plate-scale model for the Precambrian growth and evolution of the North American continent.

Plate tectonics after the 26 December 2004 Great Sumatra earthquake resulted in major topological changes in the Andaman and Nicobar islands. Aerial and land reconnaissance surveys of those islands after the earthquake provide evidence of spectacular plate ...

A seismotectonic map shows geologic, seismological, and other information that is pertinent to seismic hazards but previously was scattered among many sources. Afghanistan is part of the Eurasian plate. Afghan seismicity is driven by the relative northward ...

<p>This paper is about the analysis of metamorphosed magmatic rocks along the northern serpentinite belt (Cuba) that suggests a variety of tectonic settings of formation and metamorphism.</p>
