Journal ArticleDOI
Determination of Chromium, Nickel, Copper and Zinc in Milligram Samples of Geological Materials Using Isotope Dilution High Resolution Inductively Coupled Plasma‐Mass Spectrometry
TL;DR: In this paper, a simple and accurate method for the determination of Cr, Ni, Cu and Zn at μg g−1 levels in milligram-sized bulk silicate materials is reported using isotope dilution high-resolution inductively coupled plasma-mass spectrometry (HR-ICP-MS) with a flow injection system.
Journal ArticleDOI
Geochemical evolution of a shallow magma plumbing system during the last 500 years, miyakejima volcano, Japan : Constraints from 238U-230Th-226Ra systematics
TL;DR: In this paper, the authors investigated U-series disequilibria of rocks erupted over the past 500 years (1469-2000 AD) from Miyakejima volcano, Izu arc, Japan.
Journal ArticleDOI
Degassing, crystallization and eruption dynamics at Stromboli: trace element and lithium isotopic evidence from 2003 ashes
Federica Schiavi,Katsura Kobayashi,Takuya Moriguti,Eizo Nakamura,Massimo Pompilio,Massimo Tiepolo,Riccardo Vannucci +6 more
TL;DR: In this article, a fractional crystallization model based on major and trace element compositions, combined with a degassing model for the Stromboli volcano was proposed to reveal that abundant plagioclase precipitation and variable degrees of degassing can lead the more primitive LP magma to evolve toward a differentiated (isotopically lighter) HP magma ponding in the upper conduit and undergoing slow continuous degassinginduced crystallization.
Journal ArticleDOI
Precise isotopic determination of Hf and Pb at sub-nano gram levels by MC-ICP-MS employing a newly designed sample cone and a pre-amplifier with a 1012 ohm register
Akio Makishima,Eizo Nakamura +1 more
TL;DR: In this article, the authors used the Neptune multiple collector ICP-MS (MC-ICP-MS) with a newly designed sample cone (the Jet cone) and a new pre-amplifier with a highly resistive register of 1012 ohm.
Journal ArticleDOI
A group separation method for ruthenium, palladium, rhenium, osmium, iridium, and platinum using their bromo complexes and an anion exchange resin.
TL;DR: This new technique is suitable for simultaneous determination of subnanogram per gram of Ru, Pd, Re, Os, Ir, and Pt and Os isotope analysis in geological, mineralogical, and environmental samples without direct addition of toxic reagents required in distillation/extraction of Os or oxidizing of Ir.
