Web1 mrt. 2016 · Introduction: Due to its lithophile and strongly refractory character, Ti is an element of particular interest in planetary sciences as the range of processes susceptible of fractionating its isotopic composition is rather limited and involves primarily magmatic/metamorphic processes. Indeed, Ti is refractory and cannot easily be lost … thibault barrey
