Following the pioneering work of Goldschmidt and Peters (1932a, b), the geochemistry of
boron has been explored in intermittent bursts of activity, usually associated with …

Melt inclusions are small parcels of melt trapped in crystals within magmatic systems, and
are analogous to fluid inclusions formed by trap** of hydrothermal and other fluids during …

In its simplest interpretation, this observation implies only a few thousand years elapse
between'fluid'release from the slab, and eruption of this component in arc lavas. In most …

Fluids derived from the devolatilization of subducting slabs play a critical role in the melting
of the mantle wedge and global geochemical cycles. However, in spite of evidence for the …

This chapter reviews recycling of boron (B) and its isotopes in subduction zones. It discusses
the profound changes in B concentrations and B isotope ratios of various materials involved …

Massif-type anorthosites, enormous and enigmatic plagioclase-rich cumulate intrusions
emplaced into Earth's crust, formed in large numbers only between 1 and 2 billion years …

Mineral-hosted melt inclusions have become an important source of information on
magmatic processes. As the number of melt inclusion studies increases, so does the need to …

The fractionation of B and its isotopes between aqueous fluid and silicate melt has been
studied from 550 to 1100° C and 100–500 MPa. Fluid-melt partition coefficients are< 1 for …

New B and Li isotopic data are presented for well-characterized basalts from a transect
across the Cascades volcanic arc, S. Washington, for a sediment core on the incoming Juan …

Adakitic rocks are intermediate-acid magmatic rocks characterized by enrichment in light
rare-earth elements, depletion in heavy rare-earth elements, positive to negligible Eu and Sr …
