... of magmatic activity at 960–880, 877–710, and 550–375 Ma. Our geochemical analysis suggests that the ca. 900 Ma plutons were generated during arc magmatism and/or syncollisional crustal melting, whereas the ca. 820 Ma plutons are A-type granitoids, which are typically associated with extensional tectonism...

...; in contrast, zircon rims with flat HREE slopes yielded metamorphic ages of 224 Ma that are similar to the metamorphic ages obtained for the Baqing eclogite. In contrast, zircons from the gneiss yielded an upper-intercept age of 1033 ± 32 Ma (interpreted as the crystallization age) and a lower-intercept...

... gas and salt mining production region. To investigate the possibility of the earthquake being induced, we resolve its rupture dimension and hypocentral depth via modeling of local seismic waveforms. The result reveals that its hypocentral depth is about 4 km, much shallower than most tectonic...

... the Dongtujinhe Formation and underlying arc-related volcanic rocks is constrained to ca. 310 Ma. This age is consistent with published data for tectonic exhumation of high- to ultrahigh-pressure ([U]HP) metamorphic rocks from the northern margin of the South Tianshan orogenic belt. Zircon U-Pb ages from...

The 250–364 Ma age group corresponds to the collision between the Central Tian Shan and the Tarim block during the late Paleozoic (e.g., Gou et al., 2012 ; Huang et al., 2012 ). The 374–500 Ma age group could...
