Petrology, geochemistry and mineral chemistry of Shahrak intrusive body (East of Takab, Northwest of Iran)
The intrusive body of the Shahrak is located between the West Azarbaijan and Kurdistan provinces. Lithologically, this intrusive body consists of granodiorite, monzonite, monzodoirite and monzogobbro, which intruded into Oligo-Miocene sedimentary units and Cretaceous and Precambrian metamorphic rocks. Mineral chemistry studies of granodiorite and monzogabbro rocks show that plagioclases have la...
متن کاملPetrology and geochemistry of lavas
“This continuity disappears, however, if one considers individual parts of the [Central American] chain and examines separate groups of volcanoes within a restricted volcanic field. It then becomes apparent that the continuity of the province as a whole is the result of grouping excessively large segments of the chain.” A.R. McBirney: Compositional variations in Cenozoic calcalkaline suites of ...

15 صفحه اولStudy of Petrology and Geochemistry of west Aghda Dikes (Yazd); Using Minerals Chemistry
Diabase dikes in the West Aghda (Yazd Province) are located within the Bahramtaj mine in the Central Iran zone. These dikes are dark gray and crops out in the limestone-dolomite rocks. They are located along the east-west faults of the West Aghda. Plagioclase, biotite, amphibole, and pyroxene are the main minerals in these dikes. Plagioclases are andesine, biotite are often iron type (FeO: 24....
متن کاملMidocean Ridge Geochemistry and Petrology
The most volcanically active regions of our planet are concentrated along the axes of the globe, encircling midocean ridges. These undersea mountain ranges, and most of the oceanic crust, result from the complex interplay between magmatic (i.e., eruptions of lavas on the surface and intrusion of magma at depth) and tectonic (i.e., faulting, thrusting, and rifting of the solid portions of the ou...
