Secular evolution of continents and the Earth system
Understanding of secular evolution of the Earth system is based largely on the rock and
mineral archive preserved in the continental lithosphere. Based on the frequency and range …

When crust comes of age: on the chemical evolution of Archaean, felsic continental crust by crustal drip tectonics
The secular evolution of the Earth's crust is marked by a profound change in average crustal
chemistry between 3.2 and 2.5 Ga. A key marker for this change is the transition from …

The zircon archive of continent formation through time
NMW Roberts, CJ Spencer - 2015 - lyellcollection.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 …

Crustal rejuvenation stabilised Earth's first cratons
The formation of stable, evolved (silica-rich) crust was essential in constructing Earth's first
cratons, the ancient nuclei of continents. Eoarchaean (4000–3600 million years ago, Ma) …

What Hf isotopes in zircon tell us about crust–mantle evolution
Abstract The 176 Lu–176 Hf radioactive decay system has been widely used to study
planetary crust–mantle differentiation. Of considerable utility in this regard is zircon, a …

No evidence for Hadean continental crust within Earth's oldest evolved rock unit
Due to the acute scarcity of very ancient rocks, the composition of Earth's embryonic crust
during the Hadean eon (> 4.0 billion years ago) is a critical unknown in our search to …

Oldest rocks from Peninsular India: evidence for Hadean to Neoarchean crustal evolution
The evolution of continental crust during Hadean and Archean and related geodynamic
processes provides important clues to understand the early Earth history. Here we report …
