| Research Abstract |
Experimental studies have been conducted to investigate the relationship between the flow direction and seismic anisotropy in Earth’s upper mantle. Mantle flow was experimentally reproduced by using a simple-shear deformation technique under Earth’s upper mantle conditions, and then seismic properties of the samples were evaluated. Based on the experimental results by the present project, horizontal flow is expected to be the dominant flow style in the Earth’s upper mantle.
