Zircon crystallization and recycling in the magma chamber of the rhyolitic Kos Plateau Tuff (Aegean arc)
INTRODUCTION Approximately 160,000 yr ago, one of the largest Quaternary explosive volcanic eruptions of the Mediterranean basin occurred just offshore of the island of Kos (Greece), resulting in ~60 km of volcanic ash and pumice emplaced as pyroclastic fall and fl ow deposits over an area >2000 km (Keller, 1969; Allen, 2001; Fig. 1). In comparison to the 3500 yr B.P. Minoan eruption, which cre...
متن کاملInvestigation of the role of fractional crystallization, crustal assimilation and magma mixing in turquoise hosted sub-volcanic intrusion rocks in south of Damghan mine, Iran.
Granodiorite and dioritic intrusive rocks (Middle Eocene age) intruded the Lower-Middle Eocene volcanic rocks at the northern parts of the Torud-Chah Shirin volcano-plutonic belt in north east of Iran. This granodiorite is intruded by small rhyolitic dome in the Damghan turquoise-gold mine. According to all data, these intrusive rocks are related to a common source. The primary magma evolved by...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Magma hybridization in the middle crust: Possible consequences for deep-crustal magma mixing
The 465 Ma Svarthopen pluton in northcentral Norway was emplaced under middle-crustal conditions (~700 MPa) into metasedimentary rocks of the Helgeland Nappe Complex. The pluton is characterized by zones of mingling and mixing of gabbro/ diorite with peraluminous, garnet-bearing biotite granite. Variation in bulk-rock Sr and Nd isotope ratios are consistent with simple mixing; however, nonunifo...
متن کاملThermometry and determine the characterization of magma of Cretaceous acidic rocks using the zircon mineral morphology and compare it with whole-rock chemistry in SE Saqqez, NW Iran
Zircon is an stable mineral during post crystallization processes and preserves characters of magmatic events. Zircon morphology can give some information about temperature, nature, and source of the magma. Study of the zircon morphology of Cretaceous granitoids and acidic volcanics from the southeast Saqqez area reveals that most of the crystals are P5 and S25 types with high alkalinity (I.A.)...
