摘要:Abstract(#br)Réunion Island is the present surface expression of a major mantle plume whose homogeneity and isotopic signature, near the convergence point of many hotspot isotopic arrays, have long puzzled geochemists. This signature could, in part, reflect oversampling of t...

摘要:Abstract(#br)Continental arc lavas display geochemical signatures that reflect both mantle metasomatism by slab fluids or melts and extensive differentiation of magmas within crustal reservoirs. The relative effect of source and crustal processes are difficult to disentangle...

摘要:Abstract(#br)High field strength elements (HFSE), including Zr, Hf, Nb, Ta and Ti have low solubility in aqueous fluids and partition into dense and resistant minerals. HFSE proved useful in studying terrestrial weathering and sediment transport, but little is known about th...

摘要:Abstract(#br)Four Late Pleistocene magnesian andesites (locally called “bajaites”) from Baja California have been dated by the unspiked K–Ar method and analyzed for major, trace elements and Sr, Nd, Pb, Th and U isotopes. They display very large 230 Th excesses (50% to ...

摘要:Abstract(#br)The Crozet Plateau is a 54 Ma-old volcanic plateau that supports five islands characterized by recent volcanic manifestations that are the surface expression of a deep-mantle plume. Due to their remote location and difficult access, the Crozet Islands are poorly...

摘要:The Tabas Black Land volcanic field (14 Ma) is on the major right lateral Nayband fault, on the Lut Block, Iran. It has a central area of eroded ventd, surrounded by lavas. Lavas are tilted and folded on the east by the Nayband fault. To the west lavas are undeformed and are...

摘要:Abstract(#br)Trace metal composition of atmospheric aerosols provides clues as to emission sources and history of air masses. Atmospheric trace metal concentrations measured between 2011 and 2013 at puy de Dôme (1,465 m elevation, central France) are, on average, intermediat...

摘要:Abstract(#br)Previous studies of the Ecuadorian arc (1°N–2°S) have revealed across‐arc geochemical trends that are consistent with a decrease in mantle melting and slab dehydration away from the trench. The aim of this work is to evaluate how these processes vary along ...
