Abstract: 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 subsequently. Zircons offer robust records of the magmatic and crust-forming events preserved in the continental crust. They yield marked peaks of ages of crystallization and of crust formation. The latter might reflect periods of high rates of crust generation, and as such be due to magmatism… Expand
Continental growth and the crustal record
Abstract The continental crust is the archive of Earth history. The spatial and temporal distribution of the Earth's record of rock units and events is heterogeneous with distinctive peaks andExpand
The continental record and the generation of continental crust
Continental crust is the archive of Earth history. The spatial and temporal distribution of Earth’s record of rock units and events is heterogeneous; for example, ages of igneous crystallization,Expand
Rates of generation and destruction of the continental crust: implications for continental growth
A box model approach is adopted in a numerical model constrained by the estimated volumes of continental crust at 3 Ga and the present day, and by the distribution of crust formation ages in the present-day crust, which suggests that new continental crust was generated continuously, but with a marked decrease in the net growth rate at approximately 3’Ga resulting in a temporary reduction in the volume ofcontinental crust at that time.

Continental crust is the archive of Earth history; not just of the crust itself but of its influence on, and interactions with, the biosphere, atmosphere, hydrosphere and mantle through time. OverExpand
Mechanism of Continental Crustal Growth
The continental crust comprising the outmost 20–80 km of the solid surface of the Earth and covering ~ 41% of the Earth’s surface area is of great antiquity and contains the record of most of theExpand
Episodic Earth evolution
Abstract U–Pb ages of zircons from Precambrian granitoids and major rivers are grouped into a series of major peaks at about 2.7, 2.5, 2.1, 1.9 and 1.1 Ga. Recently these peaks have been interpretedExpand
The Architecture, Chemistry, and Evolution of Continental Magmatic Arcs
Continental magmatic arcs form above subduction zones where the upper plate is continental lithosphere and/or accreted transitional lithosphere. The best-studied examples are found along the westernExpand
A relatively reduced Hadean continental crust and implications for the early atmosphere and crustal rheology
It is widely believed that the Earth was strongly reduced during its early accretion, however, the transition from the reduced state that prevailed during Earth's early period to the modern oxidizedExpand
A Change in the Geodynamics of Continental Growth 3 Billion Years Ago
Continental Growth Spurts The appearance and persistence of continents through geologic time has influenced most processes on Earth, from the evolution of new species to the climate. The relativeExpand
Generation and preservation of continental crust in the Grenville Orogeny
Detrital zircons from modern sediments display an episodic temporal distribution of U-Pb crystallization ages forming a series of ‘peaks’ and ‘troughs’. The peaks are interpreted to represent eitherExpand


Evolution of the continental crust
It may take up to one billion years for new crust to dominate the sedimentary record, and combining models for the differentiation of the crust and the residence time of elements in the upper crust indicates that the average rate of crust formation is some 2–3 times higher than most previous estimates.

The differentiation and rates of generation of the continental crust
A new approach is developed to evaluate the rates of crust generation and hence the quantities of incompatible elements processed through the continental crust over the last 4 Ga. This relies more onExpand
The growth of continental crust
Abstract The petrological and geochemical composition of the mantle-derived igneous products that will eventually form the continental crust (protolith), the episodic nature, and the geodynamic sitesExpand
Crustal Evolution at the Central Andean Continental Margin: a Geochemical Record of Crustal Growth, Recycling and Destruction
Active continental margins are considered as the principal site for growth of the continental crust. However, they are also sites of recycling and destruction of continental crust. The AndeanExpand
Apparent episodic crustal growth arising from a smoothly evolving mantle
Crustal-growth curves are the same as crustal-age distributions only in the absence of crustal recycling into the mantle, and are likely to be very different for Earth. Phanerozoic crust is moreExpand
Progressive growth of the Earth's continental crust and depleted mantle: Geochemical constraints
A three reservoir model, consisting of the continental crust, depleted mantle and a more primitive mantle reservoir is used as a basis to account for both the present-day as well as the evolvingExpand
Granitic Perspectives on the Generation and Secular Evolution of the Continental Crust
Every geologist is acquainted with the principle of “uniformitarianism,” which holds that present-day processes are the key to those that operated in the past. But the extent this applies to theExpand
The geochemical evolution of the continental crust
A survey is given of the dimensions and composition of the present continental crust. The abundances of immobile elements in sedimentary rocks are used to establish upper crustal composition. TheExpand
Episodic growth of the Gondwana supercontinent from hafnium and oxygen isotopes in zircon
The first study that integrates hafnium and oxygen isotopes, all measured in situ on the same, precisely dated detrital zircon grains reveals that crust generation in part of Gondwana was limited to major pulses at 1.9 and 3.3 Gyr ago, and that the zircons crystallized during repeated reworking of crust formed at these times.

Evolution of the Archaean crust by delamination and shallow subduction
It is deduced that shallow subduction and recycling of oceanic crust took place in the early Archaean, and that this would have resulted in strong depletion of only a thin layer of the uppermost mantle, leading to the misfit between geochemical depletion models and geophysical models for mantle convection.
