Magmatic sulfide deposits can be subdivided into 1) Ni-Cu-PGE deposits, which have
relatively smooth mantle-normalized metal patterns, 2) Ni-Cu-(PGE) deposits, which are …

Abstract The Transmexican Volcanic Belt (TMVB) is the magmatic expression of one of the
most complex convergent margins on the planet, and as such constitutes a prime location for …

Results are reported of an exploration of mantle source lithology for intraplate magmas
using whole-rock and olivine phenocryst compositions. This analysis includes modern mid …

Abstract Post-collisional (25–8 Ma) ultrapotassic mafic magmatic rocks occur to the north of
the India–Asia collision zone within the Lhasa terrane of the southern Tibetan Plateau …

Based on an evaluation of major and trace element data for ocean island basalts (OIB), we
demonstrate that oceanic lithosphere thickness variation, which we refer to as the lid effect …

The first-row transition elements (FRTEs) are compatible to moderately incompatible during
melting in mafic and ultramafic systems. Unlike highly incompatible elements, FRTEs are …

Andesite magmatism at convergent margins is essential for the differentiation of silicate
Earth, but no consensus exists as to andesite petrogenesis. Models proposing origin of …

Understanding magmatic processes such as crystallization and melting recorded in natural
samples requires calibration of mineral–melt trace element partition coefficients (D) and their …

High-precision electron microprobe analyses were obtained on olivine grains from
Klyuchevskoy, Shiveluch and Gorely volcanoes in the Kamchatka Arc; Irazú, Platanar and …

Subduction of oceanic crust generates chemical and lithological heterogeneities in the
mantle. An outstanding question is the extent to which these heterogeneities contribute to …
