Detrital zircon populations of the South Qiangtang terrane (SQT) provide vital information for reconstructing Tethyan evolution Tibetan Plateau but are obscured by undefined affiliation detrital samples and superimposition multiple tectonothermal events. We outlined SQT based on geological mapping collated Cambrian-Triassic to investigate representative populations. Although diachronous strata ...

Adakites are magmatic rocks with specific geochemical characteristics and dynamics that provide important clues to understanding the magmatic-tectonic evolution of orogenic belts. We studied Early Triassic Nanpo adakitic pluton Luang Prabang-Loei tectonic belt in Eastern Tethys domain (Laos Sarakan) using detailed petrological, zircon U-Pb chronological, whole-rock geochemical, Lu-Hf isotope st...

The facies changes, tectonics and magmatism across the Triassic–Jurassic boundary in the southern Tethyan margin have been studied in Egypt, Sudan, Jordan and Saudi Arabia. In Saudi Arabia and Jordan an unconformable contact is recognized between the Upper Triassic and Lower Jurassic rocks. This unconformity surface is marked by the truncation of the fluvial clastics of the uppermost Triassic b...

Several transitions of Lower to Middle Turonian pelagic marl–limestone-cycles into Oceanic Red Beds were studied at high resolution to gain a better understanding of the Tethyan marine system before and during red bed initiation and development. Samples were analysed for mineralogy, geochemistry, and stable isotope composition. In particular, carbonate geochemistry of diagenetically largely una...
