The generation and evolution of the continental crust
The continental crust is the archive of the geological history of the Earth. Only 7% of the crust
is older than 2.5 Ga, and yet significantly more crust was generated before 2.5 Ga than …

Detrital zircon U–Pb age and Hf isotope constrains on the generation and reworking of Precambrian continental crust in the Cathaysia Block, South China: a synthesis
Abstract The South China Block, consisting of the Yangtze and the Cathaysia blocks, is one
of the largest Precambrian blocks in eastern Asia. However, the early history of the …

Continental arc volcanism as the principal driver of icehouse-greenhouse variability
Variations in continental volcanic arc emissions have the potential to control atmospheric
carbon dioxide (CO2) levels and climate change on multimillion-year time scales. Here we …

A change in the geodynamics of continental growth 3 billion years ago
Models for the growth of continental crust rely on knowing the balance between the
generation of new crust and the reworking of old crust throughout Earth's history. The …

Clarifying the zircon Hf isotope record of crust–mantle evolution
Zircon has played a critically important role in our understanding of the growth and evolution
of the Earth. The U–Pb isotope system as preserved in zircon, more than any other mineral …

The zircon archive of continent formation through time
NMW Roberts, CJ Spencer - 2015 - pubs.geoscienceworld.org
The strong resilience of the mineral zircon and its ability to host a wealth of isotopic
information make it the best deep-time archive of Earth's continental crust. Zircon is found in …

Episodic zircon age spectra of orogenic granitoids: the supercontinent connection and continental growth
To identify age peaks and other features in an isotopic age distribution, it is common to
perform a kernel density estimation or similar analysis. A key aspect of this estimation …

Growth, destruction, and preservation of Earth's continental crust
From the scant Hadean records of the Jack Hills to Cenozoic supervolcanoes, the
continental crust provides a synoptic view deep into Earth history. However, the information …

The building blocks of continental crust: evidence for a major change in the tectonic setting of continental growth at the end of the Archean
Oceanic arcs are commonly cited as primary building blocks of continents, yet modern
oceanic arcs are mostly subducted. Also, lithosphere buoyancy considerations show that …
