Abstract

The V_p anisotropies of two amphibole-rich rocks and two biotite-amphibole-rich rocks were measured under high-pressure conditions (up to 1.0 GPa), and calculated based on the physical properties and lattice-preferred orientation (LPO) of amphibole and biotite. The results of these studies clearly demonstrated the strong effects of the LPO of amphibole and biotite on V_p anisotropies. Previous studies pointed out the importance of [001] of amphibole and (001) of biotite for V_p anisotropy. In addition to these axes and poles, (100) of amphibole strongly affected the V_p anisotropy of the sample rocks.
