Our results show that Ti isotopes can be used to reconstruct the crystallization history and identify the magmatic series parentage of magmas that otherwise lack context, but further work is needed to identify the drivers behind Ti isotopic fractionation in igneous rocks.(************************************************************************) Order today and get fast, free shipping on purchases over 99. The δ 49Ti–SiO 2 differentiation trends, however, depend on Ti coordination in the melt and the strengths of Ti bonds in diverse Fe- and Ti-oxides, which are still uncertain.

Our model results indicate that to first order, the steeper δ 49Ti trend observed in tholeiitic versus calc-alkaline magmas is most likely due to enhanced removal of Ti into sequestered minerals at low SiO 2 concentration in tholeiitic series compared to calc-alkaline series. The mineral-melt fractionation factors allow modeling of the observed Ti isotope trends in tholeiitic and calc-alkaline rocks. PDB UI Theme Chooser - Change overall UI Colour 6.

The coordination number of Ti in silicate melts is thought to be lower than in minerals, driving magmas toward higher δ 49Ti values by fractional crystallization. PDB Zone - All mod configurations are here 3. We find that the main driver for Ti isotopic fractionation is its coordination, with four-, five-, and sixfold-coordinated Ti characterized by mean force constants of 547, 462, and 310 N/m, respectively. C> les obstructeurs potentiels sont les memes que pour la face K2. We present ab initio-derived mean force constants of Ti-bearing minerals (barium orthotitanate, potassium titanium oxide, fresnoite, diopside, geikielite, karrooite, titanite, pseudobrookite, anatase, and titanium oxide) based on density functional theory (DFT) to calculate equilibrium isotopic fractionation factors. The equilibrium Ti isotope fractionation factors of Ti-bearing minerals are essential for understanding the mechanisms driving this isotopic fractionation. Magmatic differentiation produces positive correlations between δ 49Ti and SiO 2.
