“…To examine this hypothesis, we plot previously reported experimental data of water solubility in forsterite/olivine as a function of pressure in Figure 7 (This study; Bai & Kohlstedt, 1992;Bali et al, 2008;Ferot & Bolfan-Casanova, 2012;Lemaire et al, 2004;Litasov et al, 2007;Matveev et al, 2001;Mosenfelder et al, 2006;Smyth et al, 2006;Withers and Hirschmann, 2008;Withers et al, 2011;Zhao et al, 2004). Because temperature has a significant effect on water solubility (Bali et al, 2008;Ferot & Bolfan-Casanova, 2012), only the literature data at temperatures of 1,200 to 1,300°C are plotted alongside our data in Figure 7 by considering a ± 50°C temperature uncertainty in large-volume high-pressure experiments even though data exit over a wider temperature range (e.g., Kohlstedt et al, 1996;Padron-Navarta & Hermann, 2017;Withers & Hirschmann, 2008). Additionally, because different infrared calibrations (Bell et al, 2003;Paterson, 1982;Withers et al, 2012) were adopted in these studies, all data are adjusted to the Withers et al (2012) calibration by simply using…”
