geochemistry investigations of volcanic rocks in salafchegan –khorhe sheet with emphasize on sr-nd isotopic data
salafchegan-khorhe volcanic rocks are exposed within urumieh-dokhtar magmatic belt. different kinds of volcanic and subvolcanic rocks of calc-alkaline to alkaline character have been reported throughout this magmatic belt. since, isotopic investigations are very useful for detection of magma petrogenesis and because no isotopic studies have been done in this area, so a geochemical and isotopic ...
متن کاملSynopsis of fossil decapod crustaceans from Slovakia (Western Carpathians)
In the past only very few works dealt with fossil decapod crustaceans from Slovakia. The systematic research of this group has never been fully conducted there. This contribution provides a short review of all known Mesozoic and Cenozoic fossil decapod occurrences. So far, most of the taxa were described from the Eocene and Miocene strata.
متن کاملVariations in Sr and Nd Isotopic Ratios of Mineral Particles in Cryoconite in Western Greenland
In order to better understand the source of minerals on the dark-colored ice, located in the Greenland ice sheet ablation zone, we analyzed the Sr and Nd isotopic ratios of minerals in cryoconite, which were collected from glaciers in northwest and southwest Greenland. We focused on the following: (i) comparison of the isotopes of minerals in cyroconite with those in sediments from local and di...
متن کاملGeochemical and isotopic (Nd and Sr) constraints on elucidating the origin of intrusions from northwest Saveh, Central Iran
Three intrusive granitoid bodies from northwest Saveh, central Iran, are embedded in volcanic sedimentary rocks of the Eocene,forming isolated small outcrops: Khalkhab quartz monzodioritic units (SiO2: ~52-57 wt %) to the northwest, Neshveh granodioriticunits (SiO2: ~62-71 wt %) to the northeast, and Selijerd granodioritic units (SiO2: ~63-69 wt %) to the southeast. The Khalkhab unit iscomposed...
