APPENDIX FIGURE 2. Frequency distribution diagram of pressure calculated for the low- and high-Al populations using the equation from AS1995. For the low-Al population, pressures were calculated for both 700 and 760 °C, considered to be the two end-member temperatures of the range over which the Fish Canyon hornblende crystallized. Also reported is the estimate of mineral equilibration pressure of Johnson and Rutherford (1989a; 2.4 ± 0.5 kbar). 2: T Al vs. A (Na + K) plots for each traverse across hornblende reported in Appendix 1, designed to estimate the contribution of the edenite substitution in the total T Al variation. The slopes of the regression lines consistently around 0.5 illustrate that the edenite exchange accounts for half of the total T Al variation for all analyzed phenocrysts.

APPENDIX FIGURE 3. Frequency distribution diagrams of temperature calculated for the low-Al and high-Al populations designed to show the influence of the input parameters P and XAb in the HB1994TB (left), HB1994TA (right) and BH1990 (bottom) calibrations of the Al-in-hornblende thermometer.

APPENDIX FIGURE 4. Frequency distribution diagrams of pressure calculated for the low- and high-Al populations at differ-ent temperature using the equation of AS1995. These diagrams demonstrate how sensitive the algorithm is to small changes in temperature.
