Porous asphalt (PA) pavements are widely employed in areas with wet climates. As particle enhancement inclusions mastic, mineral fillers play essential roles improving the performance of PA pavements. This study developed a coupled multiscale finite element (FE) model, involving mesostructure mixture and pavement. Four types mastic properties were four (Granodiorite, Limestone, Dolomite, Rhyoli...

The Ahetala granodiorite is located in the western section of South Tianshan Orogenic Belt (STOB), which great significance regarding dispute on closing date Ocean (STO) and tectonic evolution STOB. To determine setting petrogenesis, study petrography, electron probe microanalysis (EPMA), LA-ICP-MS zircon U–Pb geochronology, major trace elements analyses are carried out for granodiorite. Based ...

The Byarjomand Batholith with Pre-cambrian age in the north Semnan, north-central Iran, consists of granite, granodiorite, quartz monzodiorite and gabbrodiorite. These rocks have granular texture and occasionally granophyric, pertite and poicelitic textures. Crystal size distribution (CSD) studies can reveal magmatic processes. In order to determine volometric proportion, growth time and nuclea...

Sub-volcanic diorite and granodiorite intrusive bodies (Middle Eocene) and dome shaped rhyolite have intruded into Lower to Middle Eocene volcanic rocks in Torud-Chah Shirin magmatic segment. The granodiorite plutons and rhyolitic dome host turquoise and gold mineralization in Damghan mine. Intrusive bodies display characteristics of high potassium CA and meta-aluminous (diorite and some of gra...

The Sungun  copper  porphyry deposit is hosted by a Tertiary magmatic complex in  the  Azarbayjan province , northwestern Iran. The  Sungan mine  in its southern and eastern parts is limited  by early Miocene volcanic and by Late Cretaceous limestone rocks in northern and eastern parts respectively . The Sungun  deposit is associated with a suite of porphyritic granitoids and late dikes intrudi...

The study area (Bornaward granite) is located in northeast of Iran (Khorasan Razavi province), about 280 km southwest of Mashhad city. Taknar zone is an exotic block, bordered by two major faults, Great Kavir fault (Drouneh) to the south and Rivash fault in the north. A complex of granite, granodiorite, monzonite and diorite crop out at the center of Taknar zone. They are named as “Bornaward gr...
