Petrology and geochemistry of whole rock of Shahdad meteorites
In this study, meteorite pieces, with total weight of 259 grams, have been studied which is not listed in the world bulletin of meteorites. In order to classify these samples, after preparing microscopic thin sections and performing accurate petrography, using geochemical data of the major elements and trace elements of whole rock, obtained from XRF and ICPMS methods in Zarazma company’s labora...
متن کاملStudy 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 کاملGeochemistry of the Paleocene Sediments from SW Ahar: Implications for Provenance, Tectonics and Source Rock Weathering
The mineralogy and geochemistry of Paleocene shales and interbedded siltstones in the southwestern of Ahar town (NW Iran) were studied by optical microscopy, XRD, SEM, XRF, and ICP-MS techniques. The mineralogical composition, mainly characterized by calcite, quartz, feldspar, dolomite, muscovite, magnesiohornblende, chlorite, illite, montmorionite, palygorskite, and koninckite, suggests relati...

15 صفحه اولGeochemistry of metapelitic rocks from the Garmichay Area, East Azerbaijan, NW Iran; protolith nature and whole rock control on metamorphic mineral assemblages
The protoliths of metamorphosed argillaceous rocks from the Garmichay area in the East Azerbaijan province of NW Iran were clay-rich sediments of reworked nature, originating most likely from an andesite to andesite-basalt source and deposited in an active continental margin tectonic setting. The protoliths of the Garmichay metapelites experienced low to moderate chemical weathering. Andalusite...
