| 英文摘要 | The pressure-volume-temperature (P-V-T) equation of state (EoS) of two natural garnet samples along spessartine-almandine (Spe-Alm) join has been measured at high temperature up to 800 K and high pressures up to 15.46 and 16.17 GPa for Spe(64)Alm(36) and Spe(38)Alm(62), respectively, using in situ angle-dispersive X-ray diffraction and diamond anvil cell. Analysis of room-temperature P-V data to a third-order Birch-Murnaghan EoS yields: V (0) = 1,544.4 +/- A 0.4 a"<<(3), K (0) = 180 +/- A 3 GPa and = 4.0 +/- A 0.4 for Spe(38)Alm(62), and V (0) = 1,557.5 +/- A 0.3 a"<<(3), K (0) = 176 +/- A 2 GPa and = 4.0 +/- A 0.3 for Spe(64)Alm(36). Fitting of our P-V-T data by means of the high-temperature third-order Birch-Murnaghan EoS gives the thermoelastic parameters: V (0) = 1,544.6 +/- A 0.6 a"<<(3), K (0) = 180 +/- A 4 GPa, = 4.0 +/- A 0.4, (a,K/a,T) (P) = -0.028 +/- A 0.005 GPa K-1 and alpha (0) = (3.16 +/- A 0.14) x 10(-5) K-1 for Spe(38)Alm(62), and V (0) = 1,557.7 +/- A 0.9 a"<<(3), K (0) = 176 +/- A 4 GPa, = 4.0 +/- A 0.5, (a,K/a,T) (P) = -0.029 +/- A 0.005 GPa K-1 and alpha (0) = (3.04 +/- A 0.16) x 10(-5) K-1 for Spe(64)Alm(36). The results confirm that almandine content increases the bulk modulus of the spessartine-almandine join following a nearly ideal mixing model. The relation between bulk modulus and almandine mole fraction (X (Alm)) in this garnet join is derived to be K (0)(GPa) = 171.6(+/- 2.6) + 10.9(+/- 1.8)X (Alm). Present results are also compared with previously studies determined the thermoelastic properties of other garnets. |
