We derive a novel method for determining the oxidation state of a magma as zircon
crystallized, with a standard error of±0· 6 log unit ƒO2, using ratios of Ce, U, and Ti in zircon …

Identifying the oldest evidence for the recycling of hydrated crust into magma on Earth is
important because it is most effectively achieved by subduction. However, given the sparse …

Chondrite normalized rare earth element (REE) patterns of zircons generally have enriched
Ce values relative to La and Pr, and depleted Eu values relative to Sm and Gd. High Ce …

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 …

The tectonic evolution of the Neoproterozoic Arabian-Nubian Shield (ANS) is widely held as
an example of crustal growth processes. The ANS consists of continental crust formed prior …

Silicic volcanic eruptions pose considerable hazards, yet the processes leading to these
eruptions remain poorly known. A missing link is knowledge of the thermal history of magma …

The nature of Earth's earliest crust and crustal processes remain unresolved questions in
Precambrian geology. While some hypotheses suggest that plate tectonics began in the …

Over the past two decades, a significant number of discoveries of ancient zircon xenocrysts
in ocean-floor magmatic rocks have been reported. These findings provide compelling …

The goal of petrochronology is to extract information about the rates and conditions at which
rocks and magmas are transported through the Earth's crust. Garnering this information from …

The composition of the fine-grained matrix of glacial diamictites from the Mesoarchean,
Paleoproterozoic, Neoproterozoic, and Paleozoic, collected from four modern continents …
