Uranium (U) is of enormous global importance because of its use in energy generation,
albeit with potential environmental legacies. While naturally occurring U is widespread in the …

Publisher Summary This chapter summarizes the recent applications of U-series nuclides to
study weathering and river transport. The chapter focuses on the determination of time …

Oxygen concentration defines the chemical structure of Earth's ecosystems while it also fuels
the metabolism of aerobic organisms. As different aerobes have different oxygen …

On continental margins, oxidation of methane-rich fluids from the sediment often leads to
formation of authigenic carbonate pavements on the seafloor. The biogeochemical …

In the Critical Zone where rocks and life interact, bedrock equilibrates to Earth surface
conditions, transforming to regolith. The factors that control the rates and mechanisms of …

The uranium-series isotope signatures of the suspended and dissolved load of rivers have
emerged as an important tool for understanding the processes of erosion and chemical …

Understanding heavy mineral preservation is important for interpreting generation,
pathways, provenance and geochemistry of sediments. Despite this, many assumptions …

The sustainability of soil is a major issue for society. In principle, the evolution of soil
resources can be constrained by comparing the rates of soil erosion and production …

The ability to quantify how fast weathering profiles develop is crucial to assessing soil
resource depletion and quantifying how landscapes evolve over millennia. Uranium-series …

Young (< 5 kyr) olivine-and clinopyroxene-phyric ne-hawaiites from Mounts Gambier and
Schank in the Newer Volcanic Province in South Australia have been analysed for major …
