The isotopic composition of boron in crystalline rocks of the continental crust (e.g., metamorphic and igneous lithologies) varies over a wide range of −20 to +10‰, depending on the B-isotope composition of the protoliths and on fractionation effects caused by p

Boron Isotope Analysis of Geological Materials,o include other materials with low B concentrations (e.g., carbonates, basaltic glass). The accurate and precise determination of the boron isotopic composition of geological materials is however a difficult task, particularly for those where boron is present in low-concentration.

Boron Isotopes in the Ocean Floor Realm and the Mantle,cean island basalts and their implications for the B isotopic composition of the mantle. The chapter further discusses the B isotopic effects of assimilation of altered crustal materials in mantle-derived magmas. The systematics of seawater alteration on oceanic rocks are discussed, including sedime
