Arculus, R.J., 1987. The significance of source versus process in the tectonic controls of magma genesis. In: S.D. Weaver and R.W. Johnson (Editors), Tectonic Controls on Magma Chemistry. J. Volcanol. Geotherm. Res., 32: 1-12. Despite the association of certain characteristic trace-element signatures with particular tectonic environments of eruption, there are accumulating data which would resu...

Continental arcs in Cordilleran orogenic systems display episodic changes magma production rate, alternating between flare ups (70–90 km3 km−1 Myr−1) and lulls (< 20 on timescales of tens millions years. Arc segments or individual magmatic suites may have even higher rates, up several 100 s Myr−1, during ups. These rates are largely determined by estimating volumes arc crust, but do not reflect...

The Lut Block (Eastern Iran) extends over 900 km in a north-south direction and is only 200 km wide in an east-west direction. It is confined by the Nayband fault and Shotori Range on the west. The eastern edge is bordered by the Sistan suture zone and Nehbandan Fault. The northern termination of Lut Block is the depression of Kavir-e-Namak and the Great Kavir Fault. The Makran arc, including ...

The origin and tectonic implication of Early–Middle Devonian magmatism in the northern margin YB (Yili Block) remain enigmatic are important for understanding Late Paleozoic evolution Junggar Ocean southern Kazakhstan Orocline. Here, we present systematic study whole-rock geochemical Sr–Nd isotope features as well U–Pb–Hf characteristics zircon crystals newly identified Early volcanic rocks fro...

The continental crust in the overriding plate of India-Asia collision zone southern Tibet is characterized by an overthickened layer felsic composition with underlying granulite-eclogite layer. A large data set indicates that this experienced magmatism from 245 to 10 Ma, as recorded Gangdese Batholith. Magmatism was punctuated flare-ups at 185−170, 90−75, and 55−45 Ma caused a combination exter...

In recent years, the mélange model has been increasingly considered as an important way to transfer slab components arc sources in modern subduction zones. This differs from classic fluid/melt metasomatism that it invokes physical mixing of bulk sediment, altered oceanic crust (AOC), serpentinite, and mantle wedge at slab-mantle interface. However, due lack subducted sediment compositions, not ...
