Post-Collisional Plio-Pleistocene Adakitic Volcanism in Centeral Iranian Volcanic Belt:Geochemical
In the Central IranianVolcanic Belt (CIVB), north-west of Shahre-Babak, in the area of Javazm, Dehaj and khabr, about 60 subvolcanic porphyritic dacitic to rhyodacitic domes (1-10 km2) are intruded into a variety of rock sequences from Mesozoic to Early Miocene in age. These rocks are a part of Dehaj-Sardoieh belt. The CIVB contains intrusive and extrusive rocks of Cretaceous-Quaternary age. Ge...

متن کاملExperimental evidence supports mantle partial melting in the asthenosphere
The low-velocity zone (LVZ) is a persistent seismic feature in a broad range of geological contexts. It coincides in depth with the asthenosphere, a mantle region of lowered viscosity that may be essential to enabling plate motions. The LVZ has been proposed to originate from either partial melting or a change in the rheological properties of solid mantle minerals. The two scenarios imply drast...
متن کاملLithosphere-Asthenosphere and Volcanism in the Tyrrhenian Sea and surroundings - Struttura
Since the beginning of the 1980s seismic tomography studies have helped to unravel the deep structure and to constrain the kinematic models of tectonic evolution of Italy. In this chapter I describe the main features of the upper mantle structure beneath the Tyrrhenian – Apennine system obtained by jointly analysing the tomographic results with the distribution of subcrustal earthquakes. A new ...
متن کاملHow different source regions across the Middle East change aerosol and dust particle characteristics
A major question is whether different source regions across the Middle East account for changes in aerosol and dust particle characteristics, which impact Western Iran. Therefore, over a period of sampling from April 2017 to April 2018, dust particles were collected in Western Iran from different cities including Urmia, Sanandaj, Sare-Pole-Zahab, Dehloran and Abadan. The research aim is to comp...
