Table 2 Regression coefficients for figures, y = a + bx

From: An in situ experimental study of Zr4+ transport capacity of water-rich fluids in the temperature and pressure range of the deep crust and upper mantle

Figure 1: pressure (MPa) = a + b • temperature (°C) −677 ± 308 1.7 ± 0.4 0.42
Figure 3: FWHH(cm−1) = a + b • temperature (°C)
 ZrO2-H2O 175 ± 4 0.116 ± 0.006 0.995
 ZrO2-NaOH-H2O 255 ± 14 −0.19 ± 0.02 0.95
 ZrO2-SiO2-H2O 176 ± 6 −0.120 ± 0.008 0.993
 ZrO2-SiO2-NaOH-H2O 170 ± 15 −0.12 ± 0.02 0.96
  1. Note that data from the system ZrO2-SiO2-H2O are not shown because only two compositions at nearby temperatures were determined, and for those, there was no discernible temperature effect (see also Fig. 3)
