Abstract Cordilleran arcs are built by long periods of steady-state magmatism punctuated transient high-flux magmatic episodes or flare-ups. Such flare-ups, manifested as prodigious silicic volcanism and magmatism, result from geodynamic perturbations that cause elevated rates magma addition to the crust. Questions remain, however, about how quantitatively compare between flare-up modes arc aft...

Nagasari Volcano, part of the Dieng volcanic complex, is one unique volcanoes in Central Java. Around this volcano grow eruption craters, cones, and pyroclastic flow ridges. There were several 14 centers around Mount Nagasari, so it necessary to know development magmatism evolution. The aims research determine evolutionary magmatism. methodology used geological mapping petrographic analysis. ob...

Based on the isotope-geochronological (zircons, U-Pb method), petrogeochemical, and structural petrologic data, following paper provides a detailed description of characteristics Late Paleozoic basic granitoid magmatism in eastern part Kaakhem magmatic area (Eastern Tuva). During formation Shivey alkaline-granitoid Chadal gabbroid massifs period 292–283 Ma, there were revealed two stages contra...
