40Ar/39Ar thermochronology from the northwestern Dabie Shan: constraints on the evolution of Qinling–Dabie orogenic belt, east-central China
Seven structural units with distinct kinematics have been recognized in the northwestern Dabie Shan (114°E– 115°E and 31°N–32°N), east-central China. They are, from north to south: (1) the north-verging Mafan fold belt (MFB) involving early Paleozoic metamorphic rocks; (2) the Liangting melange belt (LMB), which is separated from the MFB by a south-dipping thrust and consists of gneissic and ma...
متن کاملMineral chemistry of magnetite and fluid inclusions studies in the Kuh-Baba iron deposit, south of Hashtroud, NW Iran
The Kuh-Baba iron ore deposit is located about 70 km south of Hashtroud, East-Azarbaidjan Province, NW Iran. The deposit is genetically affiliated with intrusive bodies of gabbroic to dioritic composition. The principal host rocks for the Fe mineralization include units of gabbro-norite and pyroxene hornblende gabbro-norite. The widespread alteration zones which are accompanied with Fe-minerali...
متن کاملOre mineralogy and fluid inclusions constraints on genesis of the Muteh gold deposit (western Iran)
The Muteh gold deposit (NE of Golpaygan) in the central part of intrusive-metamorphic belt of Sanandaj-Sirjan zone comprises NW-SE trending gold-quartz vein occurred in metamorphic complex. Gold mineralization is associated with quartz veins that formed during regional deformation across the mylonitic zones in metamorphic rocks of predominantly meta-volcanic, gneiss and schist. The sulfidation ...
متن کاملConstraints on timing of peak and retrograde metamorphism in the Dabie Shan Ultrahigh-Pressure Metamorphic Belt, east-central China, using U–Th–Pb dating of zircon and monazite
The Dabie Shan Ultrahigh-Pressure Metamorphic (UHPM) Belt occupies the suture between the Yangtze and Sino-Korean blocks in east-central China. The timing of UHPM in the Dabie belt is controversial, and most recent data come from dating of zircons. Monazite has recently been recognized as useful for dating of multiple tectonic events due to its preservation of multiple growth zones, and monazit...
متن کاملIntermediate Alkali^Alumino-silicate Aqueous Solutions Released by Deeply Subducted Continental Crust: Fluid Evolution in UHP OH-richTopaz^Kyanite Quartzites from Donghai (Sulu, China)
Minerals, fluid inclusions and stable isotopes have been studied in ultrahigh-pressure (UHP) OH-rich topaz^kyanite quartzites from Hushan (west of Dongai), in southern Sulu (China). The quartzites underwent a metamorphic evolution characterized by a peak stage (3 5 GPa and 730^8208C) with the anhydrous assemblage coesiteþ kyanite I, followed by an early near-isothermal decompression stage (2 9 ...
