Isotopic composition of strontium in volcanic rocks from oahu.
Analysis of several well-documented specimens from each of the three volcanic series on Oahu gives the following mean ratios of Sr(87) to Sr(86): the Waianae series, 0.7030 +/- 0.00010 (sigma); the Koolau series, 0.70385+/- 0.00009 (sigma); and the Honolulu series, 0.7029 ++/- 0.00006 ( sigma). The mean ratio of Sr(87) to Sr(86) of the Koolau series specimens is significantly higher than the me...
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 کاملConcentration variance decay during magma mixing: a volcanic chronometer
The mixing of magmas is a common phenomenon in explosive eruptions. Concentration variance is a useful metric of this process and its decay (CVD) with time is an inevitable consequence during the progress of magma mixing. In order to calibrate this petrological/volcanological clock we have performed a time-series of high temperature experiments of magma mixing. The results of these experiments ...
متن کاملPetrography, geochemistry, magmatic evolution and tectenomagmatic setting of igneous rocks associated with Nikuyeh epithermal mineralization (west of Qazvin)
The Nikuyeh district is located south of the Tarom-Hashtjin metallogenic province in Western Alborz. Oligo-Miocene subvolcanic intrusion and Mid-Eocene volcanic rocks with composition of dacite to andesite are main igneous settings associated with Nikuyeh polymetallic epithermal ore mineralization. Igneous phase in the Nikuyeh district are porphyritic granodiorite, monzodiorite, quartz monsonit...
متن کاملMagma Composition and Igneous Rocks
Introduction In the following chapters we will find that nearly all of the varied aspects of volcanism are either directly or indirectly controlled by the chemical composition of magma and the rate at which it cools and solidifies. If you are to understand and appreciate subsequent discussions of volcanoes and related volcanic phenomena, it is essential that you have a good grasp of the basic c...
