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...

In this paper we proposed a modeling method of the electrode lift controlling plant of a n ultra high power electric furnace and verified the accuracy of the proposed model by simulation an d field test. Keyword: ultra high power (UHP) electric furnace, electric lift device, electric lift control
متن کامل40Ar/39Ar thermochronology of the Sulu terrane: Late Triassic exhumation of high- and ultrahigh-pressure rocks and implications for Mesozoic tectonics in East Asia
Structural and thermochronological data from the Sulu terrane of eastern China document the exhumation of high-pressure and ultrahigh-pressure (UHP) metamorphic rocks to upper-crustal depths by ca. 206 Ma. 40Ar/39Ar ages from K-bearing phases record recrystallization and cooling through amphiboliteand upper greenschist– facies conditions during top-to-the-NW noncoaxial shear and suggest cooling...
متن کاملuhp-directed, glucose 6-phosphate membrane receptor in Escherichia coli.
Membrane vesicles were characterized for their ability to specifically bind [14C]glucose 6-phosphate. Membranes prepared from a strain carrying a ColE1 uhp hybrid plasmid showed significantly enhanced glucose 6-phosphate binding. It is hypothesized that glucose 6-phosphate binding to these membranes is due to a uhpR-directed, membrane-bound receptor which functions in regulation of the inducibl...
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...
