Figure 2
Lattice parameters of Ge olivines of this study in comparison with literature data [the mean radius is defined as rM = (〈rM1〉 + 〈rM2〉)/2]; filled circles: this study; open circles: Ca silicate olivines; crossed squares: M2SiO4 olivines (M = Ni, Mg, Co, Fe and Mn). References to literature data are compiled in Table 4; standard deviations are smaller than the symbols if not displayed; lines fitted to the data are guides to the eye. |
