Appinite-granite suites commonly occur within collisional orogenic belts, providing an opportunity to monitor lithospheric evolution and the geodynamic processes involved. Il est désormais complètement englouti dans le manteau terrestre, laissant peu d'indices pour. 7 ± 2. Geological setting. ABSTRACT. Derived from a complex geodynamic evolution since the Neo-Proterozoic, the Iranian region can be subdivided into several different structural domains from SW to NE: the Zagros fold and thrust belt (ZFTB), the metamorphic and magmatic Sanandaj-Sirjan zone (SSZ), the Urumieh-Dokhtar magmatic arc (UDMA), the NW Iran Block, the Central Iranian Block and the Alborz range. Considering the Neo-Tethyan tectonic process and the resulting environmental changes, a geodynamic model of “one-way train loading” is proposed to analyze the formation and evolution mechanism of the Persian Gulf Superbasin with the most abundant hydrocarbons in the world. Strike-slip ductile shearing in the MSZ and. 孙卫东 男 博导 中国科学院海洋研究所 电子邮件: weidongsun@qdio. In Arabia, and based on ammonite. The rationale for Mesogea has been derived from the perceived need for oceanic lithosphere to feed Miocene to Recent subduction beneath the Tyrrhenian and Aegean seas, the. From the Paleozoic to the Cenozoic, the Arabian Plate, North Africa and parts of Southern Eurasia, were on the margin of a series of Tethys seaways, Proto-Tethys, Paleo-Tethys, and Neo-Tethys. 21, EGU2019-4310, 2019 EGU General Assembly 2019 © Author(s) 2019. Less frequent than “normal” subduction, obduction is a first order process that remains enigmatic. 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.

Serdar Bayarı, Alexander Klimchouk, Mehmet Akif Sarıkaya,Tectonics and geodynamics of the eastern Tethys and northern Gondwana since the JurassicPeperites are volcanosedimentary materials generated by the mingling of magma and unconsolidated wet sediments. In the Early Paleozoic, paleogeography was characterized by the breakup of Rodinia and by the re-arrangement of the major continental plates in the Pangea supercontinent. The formation and evolution of the Chinese marine basins have mainly undergone two major tectonic epochs and five tectonic evolution stages. 1). Pampaphoneus is an extinct genus of carnivorous dinocephalian therapsid belonging to the family Anteosauridae.

This extinction event was associated with the development of widespread oceanic anoxia and pronounced stable carbon isotopic excursion. The subduction model of the Neo-Tethys during the Early Cretaceous has always been a controversial topic, and the scarcity of Early Cretaceous magmatic rocks in the southern part of the Gangdese batholith is the main cause of this debate.

Studying these rocks could provide key constraints on the NTO’s evolution and invaluable information on sub-ridge mantle heterogeneity. The forms of the margins of the Lhasa terrane and the Tethyan Himalaya prior to the collision of India and Eurasia as constrained by paleomagnetism are ambiguous due to the disordered Cretaceous paleomagnetic data from the central Lhasa terrane and the counterclockwise rotation of the Indian plate during the Cretaceous. Present-day Asia is the result of the assembly of continental blocks and terranes over the last 500 million years,. The area of research holds a complex geological setting with tremendous potential as a regional geodiversity. 8 km over middle-aged (ca. Approximately 251. However, how and when oceanic subduction started to transform to an intraplate environment are still open questions. 5 million years ago), this sea’s name originated from the water deity of Greek mythology ‘Tethys’ who was known as the Titaness of freshwater. The Sanandaj-Sirjan zone of Iran is a metamorphic belt consisting of rocks which were metamorphosed under different pressure and temperature conditions and intruded by various plutons ranging in composition from gabbro to granite. New zircon U-Pb dating results from the Zonggei Formation volcanics indicate that the volcanic rocks formed at ∼114–110 Ma.

Petrogenesis of the Changlinggang A-type Syenites in the WesternKristijan Rajič, Hugues Raimbourg, Vincent Famin, Benjamin Moris-Muttoni, Donald M. At least two Tethyan seas successively occupied the area between Laurasia and Gondwana during the Mesozoic Era.

Fisher, Kristin D. [1] In Greek mythology, Tethys ( / ˈtiːθɪs, ˈtɛθɪs /; Ancient Greek: Τηθύς, romanized : Tēthýs) was a Titan daughter of Uranus and Gaia, a sister and wife of the Titan Oceanus, and the mother of the river. These radiolarian assemblages indicate that the Zhongba mélange has middle Jurassic–early Cretaceous remnant, are coeval with those from the central and eastern parts of the YZSZ. 9 Ma, 92. State Key Laboratory of Lithospheric Evolution. Paleo-Tethys Ocean. Existing isotopic geochronological studies on the ophiolites reveal that they were formed around 130–120 Ma (Dai et al. The widespread Linzizong volcanic successions (LVS) in the Lhasa Terrane was a magmatic response to the tectonic transition from Neo-Tethyan oceanic subduction to the India–Asia collision, which has been the subject of many studies; however, studies on the LVS in the western Lhasa Terrane are scarce compared to those in the east, limiting. Paleomagnetic data, petrography, and rock magnetism confirm the primary nature of isolated characteristic remanent magnetizations carried by titanomagnetite and hematite. 1).

NW Iran, situated between the Arabian and Eurasian plates, carries a record of both Paleo-Tethyan and Neo-Tethyan tectonic evolution. stockari, the only orthophragminid identified in Jafnayn Formation, is quite distinct from. , Borneo, Java, and Sulawesi) that separated from the Gondwana continent, leading to the final.

The southern Myanmar tin ore district is an important part of the well-known Southeast Asia tin belt (SATB), and hosts numerous economically important primary tin-tungsten ore deposits. The paleogeography of the Tethyan Himalaya (TH) during the Mesozoic is vital to constrain the evolutionary history of the Neo‐Tethys Ocean, but reliable paleomagnetic data from Jurassic rocks in.

Similar to other ophiolites globally, the tectonic setting of the YZO remains debated. Based on previous studies (Wen et al. Tectonics. The Cenozoic Karvandar Basin is situated at the intersection of the Sistan Suture Zone and the Makran accretionary wedge, in SE Iran. 1 b).

In this intensely reworked area, severe collision and shortening lead to slab break-offs and/or superposition and greatly weaken the traceability of slab. Soils from different regions have heterogeneous Mg isotopic compositions ranging from −1. Prior to the collision of Indian and Asian tectonic plates in the Eocene epoch (~55–50 Ma), this region was part of the interior Neo-Tethys Ocean in the Cretaceous and early Paleogene (Ding et al. 作为研究全球大地构造演化的天然实验室,特提斯构造域汇集了全球最全面、最复杂的地质现象,阿尔卑斯可见微板块残片,伊朗高原微板块保存完好,青藏高原构造域可能成为造山带的混杂堆积,澳大利亚与东南亚之间正在发生陆陆.
