Development of rapid and precise Pb isotope analytical techniques using MC-ICP-MS and new results for GSJ rock reference samples
A rapid and precise routine Pb isotope analytical technique for rock samples was developed using multiple collector inductively coupled plasma mass spectrometry (MC-ICP-MS). The mass discrimination of the Pb isotope ratios was corrected with the 205Tl/203Tl ratio of a Tl isotope reference material (NIST SRM 997) added to samples. The optimization of the analytical parameters and the minimizatio...
متن کاملPotential uses of stable isotope ratios of Sr, Nd, and Pb in geological materials for environmental studies
The ratios of stable isotopes of certain elements in rocks and minerals have strong regional characteristics that are reflected in atmospheric components, in water, and in the living organisms that form Earth's surface environment as well as in agricultural and fishery products. Geologically derived stable isotope ratios can be used as a tracer for the source of many kinds of substances, with c...
متن کاملrb-sr and nd-sr isotope geochemistry and petrogenesis of the misho mountains mafic dikes (nw iran)
introduction there are some theories about the paleotethys event during the paleozoic that have been proposed by geologists (metcalfe, 2006). some scientist offered some pieces of evidence about the northern margin of gondwana (zhu et al., 2010). the paleotethys ocean and hercynian orogenic report first in iran, have been offered from the morrow and misho mountain (eftekharnejad, 1981). misho m...
متن کاملProvenance of lithogenic surface sediments and pathways of riverine suspended matter in the Eastern Mediterranean Sea: evidence from Nd/Nd and Sr/Sr ratios
In order to characterize the provenance of lithogenic surface sediments from the Eastern Mediterranean Sea (EMS), residual (leached) fraction of 34 surface samples have been analysed for their Nd/Nd and Sr/Sr isotope ratios. The sample locations bracket all important entrances of riverine suspended matter into the EMS as well as all sub-basins of the EMS. The combined analyses of these two isot...
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...
