Highly fractionated granites: Recognition and research
TL;DR: In this article, the authors proposed that granites are an important sign indicating compositional maturity of the continental crust, and they are also closely related to the rare-elemental (metal) mineralization of W, Sn, Nb, Ta, Li, Be, Rb, Cs, REEs, etc.
High Precision Iron Isotope Measurements With High Mass Resolution MC-ICPMS
S. Weyer,S. Johannes,J. Gerhard +2 more
TL;DR: In this article, a new technique for high precision measurement of iron isotope ratios using high mass resolution MC-ICPMS on the ThermoFinnigan Neptune was presented, which enables Fe isotope measurements with a Fe-isotope/interference ratio of up to 1.

Iron isotopes constrain biologic and abiologic processes in banded iron formation genesis
TL;DR: The voluminous 2.5-Ga banded iron formations (BIFs) from the Hamersley Basin (Australia) and Transvaal Craton (South Africa) record an extensive period of Fe redox cycling.

Mass spectrometry and natural variations of iron isotopes
Nicolas Dauphas,Olivier Rouxel +1 more
TL;DR: Recent advances in the geochemistry, cosmochemistry, and biochemistry of iron isotopes are reviewed, showing how high temperature processes like evaporation, condensation, diffusion, reduction, and phase partitioning can affect Fe isotopic composition.

Precise analysis of copper and zinc isotopic compositions by plasma-source mass spectrometry
TL;DR: In this paper, a procedure for the analysis of Cu and Zn isotope compositions by plasma-source mass spectrometry (Plasma 54) together with a method to purify Cu and zn from natural samples of silicates, ores, sediments, and biological material is presented.

Ca isotope fractionation on the Earth and other solar system materials
TL;DR: In this paper, it was demonstrated that differences in the Ca/^(44)Ca ratio due to mass dependent isotope fractionation in nature are clearly resolvable to a level of 0.001.
