New sample preparation techniques for the determination of Si isotopic compositions using MC-ICPMS

TL;DR: In contrast to many other non-traditional stable isotopes of the elements discussed in this book, those of silicon are not strictly speaking “Non-Traditional Stable Isotopes” because they have been studied for more than 60 years as mentioned in this paper.

TL;DR: In this article, the authors investigate the degree of Si isotopic fractionation that takes place during magmatic differentiation, and show that the Si isotope composition varies linearly as a function of silica content, with more differentiated rocks possessing heavier isotopic compositions.

TL;DR: Georg et al. as discussed by the authors measured high precision Si isotope ratios for a series of meteorites and terrestrial samples using high-resolution multi-collector ICP-MS and found that the terrestrial samples are higher than values for chondrites.

TL;DR: In this paper, the authors used piston cylinder experiments to document the thermal isotopic fractionation of all the major elements of basalt except for aluminum and the fractionation by chemical diffusion between a natural basalt and rhyolite.

TL;DR: In this article, the fractionation of silicon isotopes by three species of marine diatoms, Skeletonema costatum, Thalassiosira weissflogii, and Thalassoia sp., grown in batch culture, is reported.

TL;DR: Wang et al. as mentioned in this paper found that the SiO2 contents in ignited rice plant samples increased generally from roots, through SL (stem and leaves), to husks, which can be explained by kinetic isotope fractionation in a Rayleigh process.

TL;DR: The distribution of silicon in the North Pacific is controlled by the utilization of silicic acid by diatoms, a process that fractionates silicon (Si) isotopic compositions as discussed by the authors.
