Mineralogical Controls on the Ti Isotope Composition of Subduction Zone Magmas

Mineralogical Controls on the Ti Isotope Composition of Subduction Zone Magmas

Abstract The positive Ti isotope versus SiO2‐content correlation in igneous rocks reflects the fractional crystallization of Ti‐bearing oxide minerals. However, Ti isotope variations of subduction‐related igneous rocks indicate that the Ti isotope compositions of their mantle sources are heterogeneo...
