Mineral chemistry and thermobarometry of Eocene Alkaline volcanic rocks in the Southwest of Germi, NW Iran
Petrography and chemistry of minerals showing that Eocene alkaline volcanic rocks in southwestern of Germi (Talesh zone, NW Iran) mostly have basaltic composition. Mineralogically these rocks are composed of diopsidic clinopyroxene and labradoritic plagioclase phenocrysts. The microlithic and glassy groundmass composed of sanidine, clinopyroxene, biotite, pargasitic amphibole and magnetite asso...
متن کاملInvestigation of mineral chemistry, thermobarometry and fuzzy equilibrium of the basic Plio-Quaternary volcanic rocks in NE Varzeghan
1- Introduction The studied area is situated in northeast Varzeghan in East Azerbaijan Province. In the classification of the structural unites of Iran, this area is a part of Ahar-Arasbaran magmatic arc. The Cenozoic magmatism in the Ahar–Arasbaran region started in the Eocene with an intensive volcanic activity that produced widespread basic to felsic rocks and continued in the Oligo-Miocene...
متن کاملChemistry of mafic minerals and thermobarometry of Bazman Quaternary volcanic rocks
Abstract 1-Introduction Bazman volcano is located on Chgay - Makran magmatic arc. This magmatic arc with east-west trend is 500 km long and 150 km wide and extends from southeastern Iran to southwestern Pakistan. Early evolution of the Makran zone from the upper Oligocene to the upper Miocene is characterized by turbidite sediments deposited on the oceanic crust. There are several quaternary...
متن کاملMineral chemistry and Thermobarometry of Talkh-rud Sub-volcanic Intrusion, Damavand Volcano
Introduction Damavand volcano is situated in the central part of the Alborz mountain range along the southern margin of the Caspian Sea, North of Iran and also located about 50 km NE of Tehran. The basement of the volcano is made up of Paleozoic to Cenozoic sediments. Damavand stratovolcano consists mainly of trachyandesite-trachyte lava flows and pyroclastics formed in the past two Ma (Allenb...
متن کاملPetrology and Geochemistry of the Eocene Volcanic Rocks in the West of Sechangi, Lut Block
The Eocene volcanic rocks exposed in the NW Sechangi area of Lut block, include pyroclastic deposits and lavas. These volcanic rocks are basalt, basaltic andesite, andesite, andesite-trachyandesite, trachydacite, dacite and rhyolite-ignimbrite in composition. Based on our field observations, the volcanic rocks erupted in four stages in the aquous to subaerial environments. The volcanic rocks ar...
