Figure 3
The unit-cell volume of NaM3+(Si,Ge)2O6 pyroxenes. Filled red squares represent the data from this study, and filled blue triangles represent the data for NaM3+Ge2O6 from the literature, for Cr3+ taken from Redhammer, Roth & Amthauer (2008) and Nenert et al. (2009), for V3+ from Emirdag-Eanes & Kolis (2004), for Fe3+ from Redhammer et al. (2011) and for Mn3+ from Chen et al. (2013). Data for silicates (crossed squares) are taken from Redhammer et al. (2003, and reference therein). |
