The biogeochemical cycling of metals in natural systems is often accompanied by stable
isotope fractionation which can now be measured due to recent analytical advances. In …

Several small pyrite±baryte±iron-oxide orebodies (Buca della Vena, Canale della Radice,
Fornovolasco, Monte Arsiccio and Pollone) are hosted in the metamorphic rocks of the …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

For this study, we generated thallium (Tl) isotope records from two anoxic basins to track the
earliest changes in global bottom water oxygen contents over the Toarcian Oceanic Anoxic …

Late Archaean sedimentary rocks contain compelling geochemical evidence for episodic
accumulation of dissolved oxygen in the oceans along continental margins before the Great …

Thallium (Tl) is typical rare element with severe toxicity comparable to Hg and Pb. To track Tl
pollution, isotopic fractionation of Tl was evaluated during pyrite smelting for sulfuric acid …

The rates of marine deoxygenation leading to Cretaceous Oceanic Anoxic Events are poorly
recognized and constrained. If increases in primary productivity are the primary driver of …

The initial rise of molecular oxygen (O2) shortly after the Archaean–Proterozoic transition 2.5
billion years ago was more complex than the single step-change once envisioned. Sulfur …

This contribution summarizes the current state of understanding and recent advances made
in the field of stable thallium (Tl) isotope geochemistry. High precision measurements of Tl …

Thallium (Tl) isotopes are a new and potentially powerful paleoredox proxy that may track
bottom water oxygen conditions based on the global burial flux of manganese oxides …
