TLDR
In this paper, the conditions controlling U isotope fractionation in selected modern anoxic basins (Baltic Sea: Landsort and Gotland Deeps and the Kyllaren fjord in Norway) and compares U with Mo isotope fractions were explored.About:

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.

Molybdenum in natural waters: A review of occurrence, distributions and controls
TL;DR: The 2011 WHO Guidelines for Drinking-Water Quality (fourth edition) advised a health-based value of 70μg/L for Mo but this is no longer promulgated as a formal guideline value as WHO consider such concentrations to be rarely found in drinking water as discussed by the authors.

Uranium isotopic compositions of the crust and ocean: Age corrections, U budget and global extent of modern anoxia
TL;DR: In this paper, the double spike technique and a new data reduction method were used to analyze an array of seawater samples and 41 geostandards covering a broad range of geological settings relevant to low and high temperature geochemistry.
Journal ArticleDOI
The Stable Isotope Geochemistry of Molybdenum
TL;DR: In the geosciences, the redox sensitivity of Molybdenum makes it particularly useful for answering questions about environmental redox conditions as mentioned in this paper, and it was first suggested as an ocean paleoredox proxy over 30 years ago (Holland 1984; Emerson and Huested 1991).
Journal ArticleDOI
Uranium Isotope Fractionation
TL;DR: A thorough review on the application of the U-decay series systems within Earth sciences was published in Reviews in Mineralogy and Geochemistry (RiMG) volume 52 in 2003, and will not be discussed further within this review as mentioned in this paper.

The continental crust: Its composition and evolution
TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.

The geochemistry of redox sensitive trace metals in sediments
TL;DR: In this paper, the authors analyzed the redox sensitive elements V, Mo, U, Re and Cd in surface sediments from the Northwest African margin, the U.S. Northwest margin and the Arabian Sea to determine their response under a range of redox conditions.

TL;DR: In this article, the authors introduce the concept of a geochemical switch, in which HS- transforms the marine behavior of a conservative element to that of a particle reactive element, and the action point of the HS- switch is calculated to be, a(HS)- = 10(-3.6) - 10(-4.3).
