The sulfur budget in magmas: evidence from melt inclusions, submarine glasses, and volcanic gas emissions
The major magmatic volatile components—H 2 O, CO 2, S, Cl, and F—play an important role
in the formation, evolution, and eruption of magma. Knowledge of magmatic concentrations …

Isotopes, DUPAL, LLSVPs, and anekantavada
The mantle perspective provided by radiogenic isotope geochemistry has evolved over the
last 40 years. Although the idea of an upper mantle depleted in incompatible elements by …

[HTML][HTML] Subduction zone geochemistry
Crustal recycling at convergent plate boundaries is essential to mantle heterogeneity.
However, crustal signatures in the mantle source of basaltic rocks above subduction zones …

[كتاب][B] Stable isotope geochemistry
J Hoefs, J Hoefs - 2009 - Springer
The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

Monte Carlo simulations of metasomatic enrichment in the lithosphere and implications for the source of alkaline basalts
One hypothesis for the origin of alkaline lavas erupted on oceanic islands and in
intracontinental settings is that they represent the melts of amphibole-rich veins in the …

Continental crust beneath southeast Iceland
The magmatic activity (0–16 Ma) in Iceland is linked to a deep mantle plume that has been
active for the past 62 My. Icelandic and northeast Atlantic basalts contain variable …

Oxygen isotope evidence for slab melting in modern and ancient subduction zones
We measured oxygen isotope compositions of 34 adakites, high-Mg andesites, and lavas
suspected to contain abundant slab and sediment melts from the Western and Central …

Two-component mantle melting-mixing model for the generation of mid-ocean ridge basalts: Implications for the volatile content of the Pacific upper mantle
We report major, trace, and volatile element (CO 2, H 2 O, F, Cl, S) contents and Sr, Nd, and

Lithium isotopes in global mid-ocean ridge basalts
The lithium isotope compositions of 30 well-characterized samples of glassy lavas from the
three major mid-ocean ridge segments of the world, spanning a wide range in radiogenic …

Lithium isotope evidence for subduction-enriched mantle in the source of mid-ocean-ridge basalts
Abstract 'Recycled'crustal materials, returned from the Earth's surface to the mantle by
subduction, have long been invoked to explain compositional heterogeneity in the upper …
