Plate tectonics (from the Late Latin: tectonicus, from the Ancient Greek: τεκτονικός, lit. 'pertaining to building') is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of Earth's lithosphere, since tectonic processes began on Earth between and billion years ago.

There are two theories of formation of Himalayas mountains, the first theory is “The Geosyncline Theory” and the second theory is “The Plate Tectonic Theory”. In this article, we’re going to learn about the Geosyncline Theory.
million years ago the super continent Pangea started to disintegrate into smaller continents. This book collects the broad range of data that’s been gathered on the Himalayas over the past 50 years, providing a comprehensive analysis and interpretation on the available data that brings the scientific community a better understanding of the geological diversity and structure of the Himalayan belt, along with new techniques that have.
Diverging interpretations and incompatible scenarios have been proposed for the early stages of Himalayan history. Numerous researchers have postulated that northern India was involved in ophiolite obduction, arc–continent, or continent–continent collision during the Late Cretaceous or Early Paleocene, but firm geological evidence was never by: Geologic Formation of the Himalaya Rasoul Sorkhabi.
The Himalaya, located on the southern fringe of the Tibetan Plateau, form a mountain arc (convex toward the south) about km long and km wide; they are bounded by two structural bends on the northwest (Nanga Parbat, the Indus gorge) and northeast (Namcha Barwa, the Tsangpo gorge).
places the Tethyan Himalayan Sequence over the Greater Himalayan Crystalline Complex (e.g., LeFort, ; Yin and Harrison, ).
These studies generally neglect signiﬁ cant differences in geological relationships along the Himalayan strike and have treated Himalayan evolution as a two-dimensional problem in cross-section view. There are many hypothesis regarding the origin of Himalaya, however there is almost a complete unanimity that the Himalayan mountains have come out of a great geosyncline called the Tethys Sea.
The Himalaya is formed in different phases, hence it does not comprises a single range but a series of at least three ranges running more or less parallel to one another. 1. Origin of the definition Systematic study of flysch began after it was introduced by Studer () for a sequence of Upper Cretaceous sandstone and mudstones in the Siemmenthal region of Switzerland.
A good account of original flysch has recently been pro- vided by Caron et al. Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene.
Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of.
Geosyncline originally called a geosynclinal is an obsolete geological concept to explain orogens which was developed in the late 19th and early 20th centuries before the theory of plate tectonics was envisaged. A geosyncline was described as a giant downward fold in Earth's crust with associated upward folds (geanticlines, geanticlinals) that preceded the climax phase of orogenic deformation.

Rasnitsyn. In Press, Journal Pre-proof, Available. The Western Interior Cretaceous Seaway was highly dynamic throughout its history; its temperature, chemistry, circulation patterns and levels, stratification characteristics, shape and size varied greatly, and episodically in concert with tectonic, eustatic, and climatic factors and their interaction.
To decipher the exhumation history of the margin between 17 and 5 Ma, we performed a coupled apatite fission track (AFT) and (U–Th–Sm)/He (AHe) study in the Cap Bougaroun Miocene granite.

A study of the surface and subsurface geology of the Zagros mountain belt reveals that, from the viewpoint of tectonic fabrics and the cause of diastrophism, the Zagros geosyncline can be divided.
A geosyncline is a very elongated structural trough in which a great thickness of sedimentary and/or volcanic rock has been deposited. Hall () observed that the Paleozoic sedimentary sequences in New York State show a systematic thickening from west to east across the state. Dana () observed that this type of thickening is common in most mountain ranges, and he showed that such.

The eight Upper Cretaceous sections were analyzed in this study and 12 planktonic foraminifera zones were recognized based on available data. Quantitative measurements were made using a Graphic Correlation with Graphcor software and correlated to the world standard Cretaceous Composite Section (MIDKCS).
Cretaceous is characterized by high atmospheric CO2 concentration and a resultantly high temperature. Thus, the Earth system, which operated during the greenhouse condition, can be deduced by the investigation of the paleoclimate during the Cretaceous.
However, information of paleoclimate from continental inland-basins is scarce compared to that from continental margin marine-basins. This book addresses the geology of the entire Himalayan range in Nepal, i.e., from the Gangetic plain in the south to the Tethyan zone in the north.
Without a comprehensive look at the various Himalayan zones, it is practically impossible to fully grasp the processes at work behind the formation and development of the spectacular Himalaya.

The Palgongsan Fault comprises growth fault, dormant, and strike-slip phases. The strike-slip phase is manifested by the Palgongsan strike-slip fault, which sinistrally offsets the Palgongsan Granite and the earlier strata. The Palgongsan strike-slip fault shows various amounts of slip within the extent of the fault, but the maximum observed slip is about km as measured in the Hasandong.
The Lesser Himalayan crystalline thrust sheets were emplaced soon after deposition of the Dumri Formation, ∼15–10 Ma. Paleocurrent and lithofacies data from the Dumri Formation indicate deposition by west‐southwestward flowing rivers that drained into the Indus portion of the Himalayan foreland basin system during the early Miocene.
Compilation of published and new data on the distribution, timing, and composition of igneous rocks, ore deposits, and metamorphic rocks in the east-central Great Basin reveals systematic relations among Cretaceous magmatism, mineralization, metamorphism, and deformation.
The geology of the Himalaya is a record of the most dramatic and visible creations of modern plate tectonic forces.
The Himalayas, which stretch over km between the Namcha Barwa syntaxis in Tibet and the Nanga Parbat syntaxis in Kashmir, are the result of an ongoing orogeny — the result of a collision of the continental crust of two tectonic plates.
This study presents a comprehensive review of the published literature on the evidences of a changing climate in the Indian Himalayan Region (IHR) and its impacts on the glacio‐hydrology of the region.

After an epicontinental phase, the sedimentary rocks in the Tibetan Himalayas document a complete Wilson cycle of the Neo-Tethyan (Tethys Ill) evolution between the Gondwana supercontinent and its northward drifting margin (Lhasa block) from the Late Permian to the Eocene. During the Triassic rift stage, the basin was filled with a huge, clastic-dominated sediment wedge with up to > 5 m of.

Prior studies of Mesozoic biodiversity document a diversity peak for dinosaur species in the Campanian stage of the Late Cretaceous, yet have failed to provide explicit causal mechanisms. We provide evidence that a marked increase in North American dinosaur biodiversity can be attributed to dynamic orogenic episodes within the Western Interior Basin (WIB).

The active Himalayan orogen has experienced intense Cenozoic deformation, high-grade metamorphism, and widespread syncollisional anatexis (e.g., LeFort, ; Yin, ). These processes have created many uncertainties in reconstructing the original geologic framework and thus the evolution of the Himalayan oro-gen.

Scientists have found that, despite a vast difference in precipitation between the north and south sides of the Himalaya Mountains, rates of erosion are indistinguishable across these mountains.ABSTRACTThe Lower Cretaceous lacks detailed comprehensive study of source rocks geochemistry characteristics and thermal evolution history as the target stratum of potential regional oil-gas exploration in the HaRi Sag, Yin-E Basin.
Organic geochemistry methods were first applied to detailed study of organic matter content, type and maturity of Lower Cretaceous source rocks from the HaRi Sag.The early history of erosion of the Himalayan orogenic belt (Fig.
