Extensive terranes of basement reactivation are interpreted as resulting from crustal thickening following continental collision. It is suggested that terranes, such as the Grenville Province and much of the Variscan orogenic belt in Europe, have their modern analog in the Tibetan Plateau. The Tibetan Plateau is underlain by a continental crust between 60 and 80 km thick and is characterized by extensive high-potash Neogene vulcanism. Following T. H. Green's arguments that partial melting of a… Expand
Plate and intraplate processes of Hercynian Europe during the late paleozoic
Abstract It is speculated that until Late Carboniferous time the region of Hercynian Europe was occupied by an elongated island arc system underlain by a segment of continental crust. In the UpperExpand
Crustal–lithospheric structure and continental extrusion of Tibet
Abstract: Crustal shortening and thickening to c. 70–85 km in the Tibetan Plateau occurred both before and mainly after the c. 50 Ma India–Asia collision. Potassic–ultrapotassic shoshonitic andExpand
Crustal rheology of the Himalaya and Southern Tibet inferred from magnetotelluric data
The Cenozoic collision between the Indian and Asian continents formed the Tibetan plateau, beginning about 70 million years ago. Since this time, at least 1,400 km of convergence has beenExpand
Distribution and tectonic setting of plutonic rocks of the Arabian Shield
Abstract Although it is still not possible to model in detail the tectonic evolution of the Arabian Shield, its evolution can be interpreted in terms of the classic pattern of Phanerozoic plateExpand
Outward-growth of the Tibetan Plateau during the Cenozoic: A review ☆
Abstract The surface uplift history of the Tibetan Plateau (TP) offers a key testing ground for evaluating models of collisional tectonics and holds important implications for processes ranging fromExpand
The Cretaceous‐tertiary deformation of the Lhasa Block and its implications for crustal thickening in Tibet
The strong Tertiary deformation of the northern margin of the Indian plate and of the Tsangpo suture zone is not matched by comparable deformation within the Lhasa block, yet the southern margin ofExpand
Geology of the Ulugh Muztagh area, northern Tibet
Abstract Within the Ulugh Muztagh area, north central Tibet, an east–west-trending ophiolitic melange marks a suture that apparently was formed during a late Triassic or slightly younger collisionExpand
Cenozoic tectonic evolution of Asia: A preliminary synthesis
Abstract Asia has been a major testing ground for various competing models of continental deformation due to its relatively well-understood plate boundary conditions in the Cenozoic, exceptionalExpand
Chapter 1 Precambrian Rocks in the Light of the Plate-Tectonic Concept
Abstract Two geophysical constraints limit the style of tectonic processes in the Precambrian: heat production and palaeomagnetism. A high rate of heat production by radiogenic decay implies mantleExpand
Precambrian Continental Crust of India and Its Evolution
The Indian Precambrian continental crust exhibits a variety of geological features fashioned at different times by different geotectonic processes. The bulk of this crust was formed prior to 2600Expand


Possible Precambrian Obduction and Plate Tectonics in Southeastern Africa
IN the theory of plate tectonics, the term “obduction zone” has been introduced recently1,2 to describe a region where slabs or slices of oceanic crust and mantle have been over-thrust onto aExpand
Mountain belts and the new global tectonics
Analysis of the sedimentary, volcanic, structural, and metamorphic chronology in mountain belts, and consideration of the implications of the new global tectonics (plate tectonics), strongly indicateExpand
Pre-Permian Global Tectonics: A Tectonic Test
Post-Permian sea-floor spreading coupled with fragmentation and widespread drift (> 1,000 km) of large segments (>107 km2) of continental crust appear established. However, studies of the nature andExpand
Lithosphere Plate-Continental Margin Tectonics and the Evolution of the Appalachian Orogen
In terms of plate tectonic theory, and by analogy with modern continental margins, the Appalachian orogen evolved through a sequence of interrelated sedimentation-deformation-metamorphism patternsExpand
Mesozoic California and the Underflow of Pacific Mantle
The Mesozoic evolution of California is interpreted as dominated by the underflow of oceanic mantle beneath the continental margin. Underflow during part of Late Cretaceous time of more than 2000 kmExpand
Paired Metamorphic Belts of the Gondwanaland Precambrian and Plate Tectonics
RECONSTRUCTIONS of Gondwanaland, based on geological arguments, paleomagnetic data and best fit of continents have derived two possible models of reassembly1–5. The most popular places India–CeylonExpand
A Reappraisal of Some Aspects of Precambrian Shield Geology
Attention is drawn to some of the misconceptions regarding the ancient crystalline shields, and an attempt is made to clarify some of the ideas held on their geology. In Southern Africa, theExpand
A precambrian suture in the Canadian shield
Abstract Linear belts of distinctive oceanic and geosynclinal deposits found on the continents have recently been interpreted as marking sutures or join lines between collided continents. ExamplesExpand

A comparison has been made between the average compositions of the granites in the Variscan, Caledonian, and Alpine orogenic belts of western Europe. Their respective compositions lie near theExpand
