Eu isotope fractionation and hydrothermal alteration.

ABSTRACT: Europium (Eu) has two naturally stable isotopes (¹⁵¹Eu and ¹⁵³Eu). The Eu anomalies produced by feldspar crystallization during magma differentiation have provided valuable geochemical information for understanding the evolutionary history of magma in the crust-mantle system. Recently, the correlation between the degree of Eu isotope fractionation (δ¹⁵³Eu) and the magnitude of the Eu anomaly produced by magma differentiation has received much attention as a new research field for understanding the evolution of the Earth system^1-4. Here, we report large variation of Eu isotope ratio for geochemically mafic volcanic rocks from the Korean Peninsula and Ocean Drilling Program (ODP) site 801 C, western Pacific Ocean. The Eu isotope ratio in this work
