In subduction zones, two major mass fluxes compete: the input flux of altered oceanic crust
and sediments subducted into the mantle and the output flux of magma that forms the …

Combined Pb‐Sr‐Nd‐Hf‐Os isotopes, together with major and trace element compositions,
were determined from clinopyroxene and olivine phenocrysts, along with whole rocks, for …

Thirty new high‐precision U‐Pb perovskite and zircon ages from kimberlites in central North
America delineate a corridor of mid‐Cretaceous (115–92 Ma) magmatism that extends∼ …

Sr‐Nd‐Pb‐Hf isotopic compositions of postshield lavas from two pairs of Hawaiian
volcanoes, Mauna Kea and Kohala (Kea trend) and Hualalai and Mahukona (Loa trend) …

The petrogenesis of Cenozoic alkaline magmas in the West Antarctic Rift System (WARS)
remains controversial, with competing models highlighting the roles of decompression …

We have measured Ni, Ca, and Mn in olivine phenocrysts from volcanoes in the Galápagos
Archipelago to infer the mantle source lithologies. Results show that peridotite is the …

The plume‐orogenic lithosphere interaction may be common and important for the
generation of large igneous provinces. The information regarding such a process is …

We discuss the spatial and temporal variation in the geochemistry of mantle sources which
were sampled by the Eocene to Quaternary mafic magmas in the vicinity of the Afar and …

Ocean intraplate volcanoes (OIVs) are formed in a sequence of stages, from large to small,
that involve a systematic progression in mantle melting in terms of volumes and melt …

The Amsterdam–St Paul (ASP) oceanic plateau results from the interaction between the ASP
hot spot and the Southeast Indian ridge. A volcanic chain, named the Chain of the Dead …
