WebApr 6, 2024 · Crystal preferred orientations and seismic anisotropy of amphibole play a crucial role in fingerprinting the rheological and physical properties of the deep crust. This study presents typical naturally deformed (banded, mylonitic, and ultramylonitic) amphibolites from the Ailao Shan-Red River shear zone (ASRR-SZ), southwestern China. WebAs the mantle flows, mineral crystals align in certain directions. Earthquake waves that pass through the aligned crystals travel faster in one direction than another. As a result, the waves split into two parts and are characterized by …
