Geochemistry of the Northern Izu-Bonin arc: implications for crustal recycling and mantle processes
… of this study is to better understand chemical recycling at destructive plate boundaries.<br/>Isotopic, major and trace element data of lavas sampled at varying distances from the trench in<br/>the Izu-Bonin arc provide constraints on the different types of flux that influence subduction …

Compositional Diversity in Arcs: A Record of Magmatic Processes in the Peru Coastal Batholith, Ica
<p>Peruvian granitic plutons display evidence for crustal recycling and magma mixing. Evidence of physical and chemical processes operating during the formation of the Ica-Pisco complexes involves magma mixing and mingling as result of felsic and mafic interactions. Evidence of crustal recycling …

The Global Detrital Zircon Database: Quantifying the Timing and Rate of Crustal Growth
… This project entailed three subprojects: 1. crustal growth/crustal recycling patterns, 2. a provenance study of the Triassic Dry Fork Formation of the Danville-Dan River Rift basin of Virginia and North Carolina, and 3. sample size issues in detrital zircon studies. The global detrital zircon …

Evolution of continental crust in the Proterozoic : growth and reworking in orogenic systems
… between juvenile mantle derived extraction, infracrustal reworking and crustal recycling, needs to be estimated. Since the beginning of the century, the use of coupled in situ zircon U–Pb, Lu–Hf and O isotope analyses as a tool to address these questions have increased exponentially. Numerous …

Tectonic and magmatic processes during extension in planetary lithospheres : rifting, spreading, delamination, and recycling on Earth and Venus
… along Venus’ rifts that may represent localized recycling of the crust driven by the delamination of eclogite roots at the base of the crust. Finally, we test that hypothesis for rift-embedded coronae formation and link their formation to global geodynamics, highlighting that Venus’ regional …

The composition of noble gas and co2 in the european subcontinental lithospheric mantle
… refertilization, magmatic degassing, volatile recycling, and mixing of volatiles modified the pristine composition of fluids stored in European SCLM and give clues on its geodynamic evolution. Mantle xenoliths from a few key regions where magmatism occurred in different temporal and geodynamic …
