内容記述 |
P-wave velocities (Vp) were measured for nine samples of granulite facies metamorphic rock from the early Paleozoic Liitzow-Holm Complex, East Antarctica. The measurements were done at pressures from 0.1 Gpa to 1.0 Gpa and at temperatures from 25℃ to 400℃ with a piston-cylinder apparatus. Vp values of the ultrabasic-basic granulites range from 6.65 to 7.29 km/s at 1.0 Gpa and 25℃. The felsic gneiss shows nearly constant Vp value from 25℃ to 400℃ at 0.6 and 1.0 Gpa, whereas it exhibits rapid decrease of Vp with increasing temperature at 0.4Gpa. In all rock samples measured, the biotite-two pyroxene granulite shows the strongest negative thermal effect of Vp (0.45 km/s). This strong thermal effect is attributed to relatively higher biotite abundance. |
