Paleozoic metamorphism in the Qinling orogen, Tongbai Mountains, central China
The Qinling orogen (Fig. 1) extends for over 2000 km across central China, separating the Archean and Proterozoic Sino-Korean block in the north from the Proterozoic Yangtze block in the south. Although the orogen has been recognized as a continental collision zone for some time, the nature, age, and duration of the collision have been the subject of considerable debate (see review in Hacker et...
متن کاملU=Pb zircon ages constrain the architecture of the ultrahigh-pressure Qinling–Dabie Orogen, China
New SHRIMP and TIMS zircon ages, Ar=Ar ages, and eclogite locations contribute significantly to our understanding of the ultrahigh-pressure Dabie Shan. (1) The geographic extent of the Yangtze craton that was subducted to ultrahigh pressure extends to the northern edge of the Dabie Shan. (2) The northern half of the Dabie Shan is a magmatic complex, intruded over a 10-Myr interval between 137 a...

متن کاملOrigin of unusual HREE-Mo-rich carbonatites in the Qinling orogen, China
Carbonatites, usually occurring within intra-continental rift-related settings, have strong light rare earth element (LREE) enrichment; they rarely contain economic heavy REE (HREE). Here, we report the identification of Late Triassic HREE-Mo-rich carbonatites in the northernmost Qinling orogen. The rocks contain abundant primary HREE minerals and molybdenite. Calcite-hosted fluid inclusions, i...
متن کاملMineral chemistry using for evaluation of the Esmaeilabad granite generation in the Posht-e-Badam area (Central- East Iranian Microcontinent)
The Esmaeilabad granitic body with the Late Triassic age is situated in the central part of the Posht-e-Badam block (Central- East Iranian Microcontinent), in the northeastern of the Yazd Province. This granitic body cross cut the metamorphic rocks of the Posht-e-Badam complex and covered by the Cretaceous limestone. Rock forming minerals of the studied granites are K-feldspar (orthoclase), pla...
