Analysis of δ18O in igneous zircons of known age traces the evolution of intracrustal recycling and crust-mantle interaction through time. This record is especially sensitive because oxygen isotope ratios of igneous rocks are strongly affected by incorporation of supracrustal materials into melts, which commonly have δ18O values higher than in primitive mantle magmas. This study summarizes data for δ18O in zircons that have been analyzed from 1,200 dated rocks ranging over 96% of the age of… Expand
Primitive oxygen-isotope ratio recorded in magmatic zircon from the Mid-Atlantic Ridge
Abstract The oxygen-isotope composition of the Earth’s upper mantle is an important reference for understanding mantle and crust geochemical cycles. Olivine is the most commonly used mineral forExpand
Crustal evolution and recycling in a juvenile continent: Oxygen isotope ratio of zircon in the northern Arabian Nubian Shield
Abstract Crustal recycling patterns during the evolution of the Neoproterozoic Arabian-Nubian Shield (ANS) were defined using the oxygen isotope ratio of zircon [δ18O(Zrn)]. Evidence for early (~Expand
Diversity in early crustal evolution: 4100 Ma zircons in the Cathaysia Block of southern China
Results from SIMS U-Pb and O isotope ratios and trace element analyses for two detrital zircons from a Paleozoic quartzite at the Longquan area of the Cathaysia Block suggest a granitoid source generated from dry remelting of partly oxidizing supracrustal sediments altered by surface waters. Expand
The origin and evolution of low-δ18O magma recorded by multi-growth zircons in granite
We for the first time reported low-δ18O granites within craton in Bengbu uplift, southeast margin of North China Craton. Integrated ion microprobe study of δ18O and U–Pb age on single zircon grainsExpand
Can oxygen isotopes in magmatic zircon be modified by metamorphism? A case study from the Eoarchean Dniester-Bug Series, Ukrainian Shield
Abstract Zircon occurs as a minor constituent in most differentiated magmatic rocks. Its robustness to later modification means that its isotopic and chemical composition generally records conditionsExpand
Zircon oxygen and hafnium isotope decoupling during regional metamorphism: implications for the generation of low δ18O magmas
Measurements of U–Th–Pb, Lu–Hf and oxygen isotopes as well as selected trace and rare earth elements were carried out on zircon grains from high-grade metasedimentary rocks from the Albany–FraserExpand
A zircon petrochronologic view on granitoids and continental evolution
Abstract Temporal trends in granitoid chemistry and thermometry constrain major global changes in magmatism, tectonism or crustal thickness in the continents. Our study relies on zircon geochronologyExpand
Oxygen isotope ratios in zircon and garnet: A record of assimilation and fractional crystallization in the Dinkey Dome peraluminous granite, Sierra Nevada, California
Abstract The 119 Ma Dinkey Dome pluton in the central Sierra Nevada Batholith is a peraluminous granite and contains magmatic garnet and zircon that are complexly zoned with respect to oxygen isotopeExpand
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.

Evidence from detrital zircons for the existence of continental crust and oceans on the Earth 4.4 Gyr ago
The discovery of a detrital zircon with an age as old as 4,404 ± 8 Myr is reported, about 130 million years older than any previously identified on Earth and represents the earliest evidence for continental crust and oceans on the Earth. Expand
Oxygen isotope ratios of Archean plutonic zircons from granite–greenstone belts of the Superior Province: indicator of magmatic source
Zircons commonly preserve primary magmatic oxygen isotope ratios even through high grade metamorphic events unlike quartz which more readily loses its primary δ18O value by subsolidus exchange.Expand

Oxygen-isotope evidence from ancient zircons for liquid water at the Earth's surface 4,300 Myr ago
In situ U–Pb and oxygen isotope results for detrital zircons found within 3-Gyr-old quartzitic rocks in the Murchison District of Western Australia are consistent with the presence of a hydrosphere interacting with the crust by 4,300 Myr ago and are postulated to form from magmas containing a significant component of re-worked continental crust.
