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 …

Abstract The Early Jurassic Toarcian oceanic anoxic event (T-OAE) was marked by
deposition of organic-rich sediments and a pronounced negative carbon-isotope excursion …

We present a comprehensive geochemical data set for the most recent volcanics from the
Mariana Islands, which provides new constraints on the timing and nature of fluxes from the …

A global selection of 56 mid-ocean ridge basalt (MORB) glasses were analysed for Li and B
abundances and isotopic compositions. Analytical accuracy and precision of analyses …

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 …

Tourmaline is the most important borosilicate mineral because of its ubiquity and the
diversity of petrologic information that it can yield. In metamorphic rocks tourmaline can …

Study of metamorphic suites directly representing the deep subduction of altered oceanic
crust and sediments can help elucidate the geochemical evolution of the forearc-to-subarc …

Tourmaline has long been recognized as an important gangue mineral in metallic and
nonmetallic ore deposits (eg Lindgren, 1933; Bateman, 1950; Routhier, 1963; Smirnov …

AT convergent margins, the subducting oceanic slab is thought to dehydrate, producing
fluids which metasomatize the overlying mantle wedge where island-arc magma forms …

Boron contents and boron isotopic compositions were determined for modern and ancient
(Permian to Miocene) marine sediments, including pelagic clay, calcareous ooze, siliceous …
