Magmatism and tectonic settings

Journal of Geophysical Research, 1972
Mutual relationships of mobile lithospheric plates define two distinct tectonic environments each characterized by diagnostic magmatism. A compressional environment occurs at loci of plate convergence; quartz- and hypersthene-normative intermediate, acid and basic members of the calc-alkaline orogenic suite are emplaced above a dipping seismic zone.

Volcanism and tectonic setting

1988
The relationship between volcanism and tectonic setting is a diverse topic. One approach to this subject in recent years has been from a geochemical point of view, the approach being to correlate particular geochemical properties or trends in modern volcanics with their specific tectonic setting, and to use the patterns derived from modern successions ...

Tectonic Setting of Aleutian Volcanism

2014
The tectonic setting of the Aleutian volcanic arc is relatively straightforward in the context of global plate tectonics theory and, because subaerial exposures are limited to small islands along the central and western parts of the arc, local complexities can be difficult to ferret out.

North America; Plate-tectonic setting and tectonic elements

1989
Abstract This volume is about the evolution of the North America Plate. It also briefly discusses the evolution of the Pacific Ocean and the Caribbean as they relate to North America. We will briefly sketch the present outlines of the North America Plate, review the plate-tectonic development of North America in a global context, and ...

Geological and Tectonic Setting

2011
The present-day geological structure of the Carpatho–Balkan–Dinaric region is controlled by the evolution of the Tethys and Atlantic Oceans and the related movements of the European and the African Plates. The Carpathians, a continuation of the Eastern Alps, formed along the margin of the European Plate to effect the closure of the Neotethys and the ...

Tectonic settings and magma associations

Bulletin Volcanologique, 1974
The largest volumes of peralkaline silicic rocks are found in areas of epeirogenic uplift and rift formation on the continents, but they may also form in several other tectonic settings, such as the oceanic islands, during the later stages of orogenic cycles, as isolated occurrences in active mobile belts, and in areas of extensional tectonics at or ...

Tectonic Setting of the Earthquake

2014
The seismo-tectonic picture of the Lushan earthquake is clear at the scales of lithospheric plate and crustal block, but remains puzzle at the scale of seismogenic faults. Role of such ‘missing earthquakes’ in seismic hazard analysis is a question worth discussing.

Tectonic Setting and Landscape Development

2009
The Mediterranean is the westernmost part of the global-scale Alpine-Himalayan orogenic belt which stretches from Spain to New Zealand. The landscapes of the region have a long and complex history that includes both horizontal and vertical crustal movements and the creation and destruction of oceans.

Tectonic Settings of Potassic Igneous Rocks

1995
Modern potassic igneous rocks occur in a wide range of tectonic settings, from continental to oceanic and within-plate, some of which are not apparently associated with subduction (Joplin 1968; Morrison 1980; Muller et al. 1992b). It is therefore important, whether improving exploration models for ancient mineral deposits, or reconstructing ancient ...

Tectonical-Geophysical Setting of the Caucasus

2012
Many outstanding geologists such as G. V. Abikh, I. M. Gubkin, V. E. Khain, K. N. Paffenholtz studied the Caucasus. The Caucasus comprises four main morphological and tectonic units (Khain and Koronovsky 1997): (1) the Ciscaucasian plain (Scythian platform), including the foredeeps of the Greater Caucasus; (2) the Greater Caucasus itself, stretching in
