“…Qualitatively, there is an excellent agreement between the fitted peaks derived from this study for [TiChu-PD] with 3,572 and 3,525 cm À1 as main peaks (red in Figure 4) with experimental Jollands et al, 2016) and natural olivine from spinel peridotites (e.g., San Carlos olivine, Schmädicke et al, 2013;Turner et al, 2015). The fitting peaks are also in agreement for [Si] peaks with main bands at 3,612, 3,581, and 3,566 cm À1 (blue spectra in Figure 4) compared to synthetic (Bali et al, 2008;Férot & Bolfan-Casanova, 2012;Lemaire et al, 2004;Mosenfelder et al, 2006;Padrón-Navarta et al, 2014;Tollan et al, 2017;Withers et al, 2011) and olivine from some kimberlitic xenoliths (e.g., Doucet et al, 2014). Additionally, peak assignments are also in agreement with theoretical works based on first-principles calculations (e.g., Blanchard et al, 2017).…”
