[HTML][HTML] The Orosirian (1800–2050 Ma) plate tectonic episode: Key for reconstructing the Proterozoic tectonic record
RJ Stern - Geoscience Frontiers, 2023 - Elsevier
Eight lines of evidence indicate that the Orosirian Period in mid-Paleoproterozoic time was
characterized by plate tectonics: ophiolites, low T/P metamorphism including eclogites …

[HTML][HTML] Europium anomalies in zircon: A signal of crustal depth?
Trace element concentrations and ratios in zircon provide important indicators of the
petrological processes that operate in igneous and metamorphic systems. In granitoids, the …

Revisiting zircon Eu anomaly as a proxy for crustal thickness: A case study of the Sierra Nevada Batholith
We analyzed detrital zircon from the Sierra Nevada Batholith, western USA, to reassess
whether zircon Eu/Eu* can be used to reconstruct crustal thickness in the past. Our …

Archaean continental crust formed from mafic cumulates
Large swaths of juvenile crust with tonalite-trondhjemite-granodiorite (TTG) composition
were added to the continental crust from about 3.5 billion years ago. Although TTG …

[HTML][HTML] Regional trends and petrologic factors inhibit global interpretations of zircon trace element compositions
The trace element composition of zircon reveals information about the melt that they are

Reinitiation of modern-style plate tectonics in the Early Neoproterozoic: Evidence from a∼ 930 Ma blueschist-facies terrane in South China
When and how plate tectonics operated throughout Earth's history remain a matter of
debate. The absence of low-temperature/high-pressure metamorphic rocks during Earth's …
