We report platinum-group element (PGE) and Re concentrations, and Re−Os isotopic data for peridotites and podiform chromitite from the mid-Jurassic Coast Range ophiolite (CRO), California. Our aim is to provide insights into the formation and evolu

The Yellowstone hotspot track in the northwestern US has a 17-myr history that began with eruption of the voluminous Columbia River basalts (CRB), and produced an eastward track with the bimodal rhyolite and basaltic eruptive centers of the Snake Riv

Mantle plumes provide an attractive mechanism for generating short-duration, voluminous magmas in large igneous provinces (LIPs) while at the same time providing an explanation for the frequently associated break-up of supercontinents. This model has

Though many models of continental crustal growth rely on the assumption that juvenile crust is derived from depleted mantle of fairly uniform composition, mafic magmas derived from the mantle – potential candidates for newly formed continental crus

The origin of high-Mg melts remains one of the most highly debated questions in igneous petrology. There are two contrasting points of view, namely, (1) melt initiation in a rising high-temperature plume, and (2) mantle melting due to fluxing by wate

Mt. Takahe is a large, late Quaternary trachyte shield volcano that rises through 2000 + m of the West Antarctic ice sheet. It is composed mostly of ne-trachyte, hy-ol-trachyte, and qz-trachyte flows, with subordinate basanite, intermediate rocks, an

Co-auteur étranger; International audience; The Western Dharwar Craton (WDC) is an Archean crustal segment for which the earliest stages of developmenthave remained poorly constrained because the oldest identified lithologies are chronologically ind
Permian–Triassic strata in the Transantarctic Mountains and West Antarctica carry a significant detrital component derived from a contemporaneous magmatic belt along the Gondwana margin. Hf- and O-isotope characteristics were determined for near-co

West Antarctica experienced a complex tectonic history, which is still poorly documented, in part due to extensive ice cover. Here, we reconstruct the Cretaceous to present thermo-tectonic history of Pine Island Bay area and its adjacent coasts, base
