Indosinian tectonics in Vietnam
Comptes Rendus - Geoscience, 2008 In Vietnam, the Triassic Indosinian collision affected coevally the Truong Son belt and the Kontum Massif,which were not independent tectonic units, but parts of the same Gondwana-derived Indochina continental block. This thermotectonic event took place synchronously throughout Vietnam, during the Lower Triassic 250–240-Ma time interval, as ...

Records of Indosinian orogenesis in Lhasa terrane, Tibet
Journal of Earth Science (Wuhan, China), 2009Based on the deformation characteristics of the ductile shear zones in Sumdo (松多) Group, the quartz fabric by EBSD (electron backscatter diffraction), the data of muscovite 40 Ar- 39 Ar geochronology (220-230 Ma) from ductile shear zones and the zircon SHRIMP U-Pb chronology (190 Ma) of granites in Sumdo region, Lhasa (拉萨) terrane is thought to have ...

Mesozoic geology of southwestern China: Indosinian foreland overthrusting and subsequent deformation
Journal of Asian Earth Sciences, 2016Abstract The southwestern part of the South China Block (SCB) records Triassic and subsequent deformations and is a key region that provides evidence of the post-amalgamation tectonic evolution of Southeast Asia. Here, we outline the tectonothermal evolution of early Mesozoic orogenesis in this region using structural analysis and fission track ...

Hercynian–Indosinian Sedimento–Tectonic Evolution of the Nanpanjiang Basin
Acta Geologica Sinica - English Edition, 1996Abstract Following the orogeny in the Early Palaeozoic, the tectonic evolution of the Nanpanjiang basin in the Hercynian–Indosinian stage constituted a complete Wilson Cycle, made up of the stages of early rifting (D–P1), late rifting and passive margin developement (P2–T1), and peripheral foreland basin developement (T2–T3).

Early Indosinian magmatism in the West Qinling orogen and its tectonic implication
2023The West Qinling Orogen (WQO), which is bounded by the Qilian Orogenic Belt, Qaidam Block and the Songpan-Ganzi Block, is the western extension of the Qinling Orogenic Belt, and experienced complex tectonic evolution processes, involving the opening, subduction and closure history of the Proto- and Paleo-Tethys Oceans.

Indosinian deformation of the Songpan Garzê Fold Belt, northeast Tibetan Plateau
Journal of Structural Geology, 2005Abstract Deformation of the Songpan Garze Fold Belt, southwest China, occurred progressively during the Indosinian orogeny (ca. 230–200 Ma). Two phases of south-directed deformation are identified: D 1 , associated with pervasive thickening of the Songpan Garzi sedimentary pile and detachment of that portion of the fold belt onlapping the Yangtze ...

Distribution and geochemical features of Hercynian-Indosinian granitoids in southeastern China
Chinese Journal of Geochemistry, 1987The tectonic patterns of the Hercynian-Indosinian cycle in southeastern China can be divided into two types. The first type is the Hercynian-Indosinian eugeosynclinal system, which is situated on the outer side of the Caledonian uplift belts. The second type is the Hercynian-Indosinian fault depression zone or superimposed basin system, which is ...

Journal of Asian Earth Sciences, 2017
Abstract The Indosinian orogeny marks the termination of marine deposition and the accumulation of lower Permian to Late Triassic clastic sediments in the Youjiang Basin, South China Block. Major and trace element compositions of Early to Middle Triassic sedimentary clastic rocks from Youjiang Basin were analysed to constrain their provenance and ...

The Triassic Indosinian orogeny in East Asia - Foreword
2008La tectonique récente, du Tertiaire à l'Actuel, est omniprésente dans l'Est et le Sud-Est asiatique, et s'y manifeste notamment sous la forme de décrochements crustaux de grande ampleur, comme celui du fleuve Rouge. Pour importante qu'elle soit, cette tectonique ne saurait faire oublier les événements orogéniques antérieurs auxquels elle s'est ...
