Emergence of Continents Stabilized the Bioavailability of Boron

Terra Nova, EarlyView.
ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.

Slab segmentation, anomalous arc volcanism, and giant porphyry copper deposits in Indonesia

Most Holocene volcanoes in Indonesia display geochemical and geophysical properties characteristic of formation via mantle wedge metasomatism. However, some volcanoes (Toba, Ungaran, Muriah, Rinjani, Tambora, Sangeang Api, and Batu Tara) are anomalous ...

Boron isotopes identify deep-slab serpentinite in the source of Aleutian arc magma

Seafloor lavas of the Western Aleutian arc have isotopically heavy boron (delta B-11 to +13.4%(0)) that is negatively correlated with B content (ppm). Endmember samples are primitive dacites and rhyodacites (delta B-11 > +10%(0), SiO2 = 63%-70%, Mg# > 0 ...

Partial melting of multiple mantle domains underneath the Paleo-Tethyan cold subduction zone triggered by slab rollback

It is widely believed that the melting of mantle wedge in a subduction zone is triggered by the influx of fluids. However, experimental petrology studies have yielded conflicting results regarding temperatures for the wet solidus of mantle metasomatite ...
