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 ...

THE AGE OF TISSINT: Sm-Nd & Rb-Sr ISOTOPE SYSTEMATICS OF A MARTIAN METEORITE FALL

Introduction: The recently acquired meteorite Tissint is the first recognized fall of a depleted shergottite. Other such shergottites were found in the hot deserts (e.g., NWA 1195, Dhofar 019, DAG 476) or in the Antarctic cold desert (e.g., QUE 94201, Y980459) and, in many cases, have disturbed isotopic systematics due to terrestrial contamination [1-4]. Tissint represents the freshest sample o...

mineralogy and geochemistry of xenoliths in the eocene volcanic rocks from southwest of jandaq

the eocene volcanic rocks from the southwest of the jandaq (kuh-e-godar-e-siah, central-east iran micro-continent) are andesitic basalt and andesite in composition. these rocks contain xenoliths with granulitic mineralogy. mineral assemblage of these xenoliths is plagioclase + phlogopite + corundum + sillimanite + chlorite + phengite with granublastic, poiklioblastic and foliated textures in th...

Contrasting origins of Cenozoic silicic volcanic rocks from the western Cordillera of the United States

Two fundamentally different types of silicic volcanic rocks formed during the Cenozoic of the western Cordillera of the United States. Large volumes of dacite and rhyolite, mostly ignimbrites, erupted in the Oligocene in what is now the Great Basin and contrast with rhyolites erupted along the Snake River Plain during the Late Cenozoic. The Great Basin dacites and rhyolites are generally calc-a...

Petrogenesis and Tectonic Setting of the Young Volcanic Adakitic Rocks in Darehzereshk’s Hassan abad (SW Yazd)

Sciences, Kharazmi University Introduction Petrogenesis of continental magmatic arc is more complicated than oceanic arcs. Because some various parameters affect the composition of magmatism in the congenital margin, such as continental crust contamination, mixing with crustal magmas and the deformation phenomena from primary mantle magma (Martin et al., 2005; Eyuboglu et al., 2018; Pawley and...
