N2 - Abstract: Temperature relations of β-factors for 18O/16O fractionations in TiO2 polymorphs have been determined using the density functional theory: 1000 ln βrt(18O/16O) = 6.93039x – 0.08158x2 + 0.00116x3 + 0.08305*P 1000 ln βant(18O/16O) = 7.34275x – 0.09906x2 + 0.00153x3 + 0.08027*P 1000 ln βbrk(18O/16O) = 7.19088x – 0.09157x2 + 0.00139x3 + 0.07601*P, x = 106/T(K)2, P is pressure (GPa). The deduced relations can be applied for isotope thermometry if combined with β-factors of coexisting phases.
