Sea-land oxygen isotopic relationships from planktonic foraminifera and speleothems in the Eastern Mediterranean region and their implication for paleorainfall during interglacial intervals
The oxygen and carbon stable isotope compositions of cave speleothems provide a powerful method for understanding continental climate change. Here, we examine the question of the regionality of thisExpand

Post-collision, Shoshonitic Volcanism on the Tibetan Plateau: Implications for Convective Thinning of the Lithosphere and the Source of Ocean Island Basalts
Potassic volcanism has been widespread and semi-continuous on the Tibetan plateau since ~13 Ma, post-dating the orogenic thickening of the India—Asia collision. Volcanism may have commenced slightlyExpand

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

Controls on trace element Sr-Mg compositions of carbonate cave waters: implications for speleothem climatic records
Abstract At two caves (Clamouse, S France and Ernesto, NE Italy), cave drip and pool waters were collected and sampled at intervals over a 2–3 year period. Mg/Ca and Sr/Ca concentration ratios,Expand

Magmatic and Crustal Differentiation History of Granitic Rocks from Hf-O Isotopes in Zircon
Granitic plutonism is the principal agent of crustal differentiation, but linking granite emplacement to crust formation requires knowledge of the magmatic evolution, which is notoriously difficultExpand

Episodic growth of the Gondwana supercontinent from hafnium and oxygen isotopes in zircon
It is thought that continental crust existed as early as 150 million years after planetary accretion, but assessing the rates and processes of subsequent crustal growth requires linking theExpand

The generation and evolution of the continental crust
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 thanExpand

Mantle and Slab Contributions in ARC Magmas
Destructive plate margins are major sites of terrestrial magmatism that have long had a key role in models for the generation of continental crust and the development of chemical heterogeneities inExpand

Hadean crustal evolution revisited: New constraints from Pb-Hf isotope systematics of the Jack Hills zircons
Detrital zircon crystals from the Jack Hills metasedimentary belt, Western Australia, are the only surviving vestiges of Hadean crust and represent an extraordinary archive into the nature of theExpand

The Lesser Antilles volcanic chain : a study in arc magmatism.
Abstract The Lesser Antilles volcanic arc is related to subduction of the American plate under the Caribbean plate. The rate of subduction is low, 2–4 cm a−1, and this has been reflected, at leastExpand
