[HTML][HTML] Sources of bias in detrital zircon geochronology: Discordance, concealed lead loss and common lead correction
T Andersen, MA Elburg, BN Magwaza - Earth-Science Reviews, 2019 - Elsevier
The distribution pattern of U-Pb ages of detrital zircon in a sedimentary rock is commonly
assumed to reflect the ages of igneous or metamorphic processes in rocks that have …

Rapid oxygenation of Earth's atmosphere 2.33 billion years ago
Molecular oxygen (O2) is, and has been, a primary driver of biological evolution and shapes
the contemporary landscape of Earth's biogeochemical cycles. Although “whiffs” of oxygen …

Correlation of Paleoproterozoic glaciations based on U–Pb zircon ages for tuff beds in the Transvaal and Huronian Supergroups
B Rasmussen, A Bekker, IR Fletcher - Earth and Planetary Science Letters, 2013 - Elsevier
The rise in atmospheric oxygen between 2.45 and 2.2 Ga has been linked to the demise of a
methane-rich atmosphere and the onset of multiple glaciations, culminating in a possible …

Uranium in iron formations and the rise of atmospheric oxygen
The concept of the Great Oxidation Event (GOE), during which atmospheric oxygen rose
precipitously and perhaps to near-modern levels around 2.4–2.1 billion years ago (Ga), has …

Detrital zircon in an active sedimentary recycling system: Challenging the 'source‐to‐sink'approach to zircon‐based provenance analysis
T Andersen, H van Niekerk, MA Elburg - Sedimentology, 2022 - Wiley Online Library
The age and properties of detrital zircon in a sediment reflect properties of the rocks in which
the zircon crystallized, and not necessarily the immediate precursor of the host sediment …

Correlation of the stratigraphic cover of the Pilbara and Kaapvaal cratons recording the lead up to Paleoproterozoic Icehouse and the GOE
Abstract The Turee Creek Basin of the Pilbara Craton is critical for timing onset of the early
