This volume is intended to generate ideas for the future exploration of immature and mature basins across the Tethyan Region. To understand the oxygen fugacity (fO<SUB>2</SUB>) during subduction initiation, we examined proto-arc boninites and associated mantle peridotites from the Troodos ophiolite, Cyprus. During this time, most parts of the Zagros area, as north-eastern margin of the Arabian Plate, were covered by shallow seas with dominant warm and arid paleoclimate resulting in the deposition of thick carbonate and evaporitic strata (Motiei.

AbstractPossible plate tectonic controls on faunal diversity dynamics have been discussed in the geological literature for around 50 years. Present-day Asia is the result of the assembly of continental blocks and terranes over the last 500 million years,. The Sivas Basin in central Anatolia (Turkey) is a foreland basin that formed after the obduction of the tethyian ophiolite during late Cretaceous (Citation Guezou, Temiz, Poisson, & Gürsoy, 1996; Citation Poisson et al.

Paleomagnetic data, petrography, and rock magnetism confirm the primary nature of isolated characteristic remanent magnetizations carried by titanomagnetite and hematite. The Neo-Tethys Ocean was an eastward-gaping triangular oceanic embayment between Laurasia to the north and Gondwana to the south.

The South Ladakh ophiolites (NW Himalaya, India): an intra-oceanic tholeiitic arc origin with implication for the closure of the Neo-TethysThe word "thesis" comes from the Greek word, meaning "position", and refers to an intellectual proposition. Ophiolites are fragments of upper mantle and oceanic crust which record the tectonic evolution of ocean basins from their rift-drift and spreading stages to subduction initiation and final closure. 1). • The subduction of the NeoTethys ridge formed an EW-trending adakitic rock belt and a NS-trending compression event from Fujian province to Tibet. 1) mainly occupies the south periphery of the windswept Tibetan Plateau.

The Arabian Plate was located south of the Equator, and bordered the western Neo-Tethys Ocean (modified from Hughes, 2000). Intrusion of these magmas into a regional metamorphic sequence (the Sanandaj-Sirjan Zone) caused partial melting and formation of migmatites with meta-pelitic protoliths.

The nature, magmatic evolution, and geodynamic setting of both inner and outer Makran ophiolites, in SE Iran, are enigmatic. Orthogonal, oblique and transform rifted margins are defined by the comparison of the structural trend of the margin versus the orientation of the oceanic spreading ridge marked by marine magnetic anomalies.

Upward depletion of ophiolitic mantle is produced by melt-peridotite reaction with lateral melt/rock ratio variations in an asthenospheric upwelling column, which flows to become the horizontal.

On one hand, based on structural similarities to the ultraslow Southwest Indian Ridge and the Ligurian ophiolite, the YZO may have originated in a slowly or ultraslowly spreading MOR (Nicolas et al. It lived at the end of the Guadalupian (= Middle Permian) during the Capitanian stage, about 265 to 260 million years ago in what is now South Africa. These ages are much younger than the. Définition du sujet La ceinture alpine-himalayenne, qui s'étend de la Méditerranée occidentale à l'Indochine en passant par le Moyen-Orient, est un laboratoire naturel pour étudier la réponse magmatique à un processus de collision géodynamique en constante évolution (Prelević et Seghedi. 1. Subduction erosion transports crustal material from the upper plate at subduction zones into the mantle and, thus, likely contributes to the composition of arc magmas.

The Tethys Ocean /ˈtiːθɪs, ˈtɛ-/ TEETH-iss, TETH- , also called the Tethys Sea or the Neo-Tethys, was a prehistoric ocean during much of the Mesozoic Era and early Cenozoic Era, located between the ancient continents of Gondwana and Laurasia, before the opening of the Indian and Atlantic oceans during the Cretaceous Period.

Tethys is the name given by Eduard Suess to an equatorial ocean that extended from the westernmost Mediterranean region of today to eastern Asia during the time interval from the late Palaeozoic to the early Cainozoic, the demise of which gave rise to the present-day Alpine-Himalayan mountain ranges. 444, Yousef Sobouti Blvd (Gava Zang St. 1994－1997，中国地震局地球物理研究所，固体地球物理学，硕士.
