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 of the Gulf of Alaska

Marine Geotechnology, 1981
Abstract The Gulf of Alaska is a seismically active area within which the boundary between the Pacific and North American plates is located. This active boundary has evolved through a series of shifts from north to south as successive blocks of continental crust were moved into southern Alaska. The present plate boundary includes dominantly strike‐slip

Tectonic Setting of Chuan-Dian Region

2010
The NEE-directing motion of the Indian plate and its collision into the Eurasian plate has resulted in the formation of the world roof – the Qinghai-Tibetan Plateau with an elevation of over 4,500 m. The crustal thickness of the plateau reaches up to 60∼70 km, about 20∼30 km thicker than that of the Sichuan basin, where the crustal thickness is only ...

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 ...

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

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 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.

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 ...

On the Tectonic Setting of Submarine Slides

1982
It is suggested that in the occurrence of submarine slides there is a geological control present in addition to the well-established control by “exogenic” agents, such as deposition, toe-erosion and pore pressure conditions. This is inferred from the existence of a principle of correspondence between subaerial and subaqueous phenomena based on the ...

The Tectonic Setting of the Southern Uplands

1986
The pattern of fault-bounded sedimentary sequences established in southern Scotland can be traced for almost 600 km to western Ireland. The sediments forming this accretionary prism were deposited, in part on the floor of the Iapetus Ocean, and in part in a trench, either by longitudinal fans (mostly from the north-east) or by fans and mass-flow ...
