The Palaeo-Tethyan Realm and Indosinian Orogenic System of Southeast Asia
1989Southeast Asia is a composite of relatively stable blocks of Precambrian continental crust overlain in large part by Palaeozoic carbonate-dominated platforms. The blocks are sutured along highly deformed mobile belts characterized by deep water sediments and fragmented ophiolites.

Determination of Onset of Uplifting for the Mid‐Upper Yangtze Area Since Indosinian Event
Chinese Journal of Geophysics, 2010AbstractThe onset of uplifting of the Mid‐upper Yangtze area is constrained by the combination of analysis of apatite fission track (AFT) age and modeling of fission track length distribution. The results show that the general trend of onset of uplifting is characterized by decreasing westward in geological time for the different tectonic units in the ...

Zircon LA-ICP-MS U-Pb dating of the Jingju syenogranites in the southwestern part of Zhejiang Province shows that these rocks were crystallized in the Late Triassic at 215±2 Ma, rather than in the Cretaceous as previously proposed. The Jingju syenogranites are characterized by relatively high K2O and FeO*, and low MgO.

We re‐examine several unconformity sites in northwestern Vietnam where the Indosinian orogenesis has been defined. Field observations in the Black‐River (Song Da) region, near Son La, demonstrate that red sandtones and conglomerates, reportedly of Cretaceous age, occur unconformably above schistosed epimetamorphic middle‐Triassic sediments.

Tectonics of Late Permian-Triassic (The Indosinian Tectonic Period, 260–200 Ma)
2010Major collision and amalgamation of continental fragments occurred in the Chinese continent during the Indosinian Tectonic Event; the Lancangjiang (i.e. Lazhulung-Shuanghu-Changning-Menglian-Dak of Thailand-central Malaya Peninsula, 1 in Fig. 6.3), Jinshajiang (18 in Fig. 6.3), Qinling-Dabie (6,10 and 11 in Fig.
