| Research Abstract |
The precise role of Earth's deep mantle remains a topic of vigorous research and debate requiring improved resolution of the structure. It is, therefore, necessary to investigate not only the details of regional seismic velocity structure but also compositional effects based on mineral physics. Therefore I performed seismological and mineral physical joint modeling on seismic anisotropy and velocity heterogeneity in the bottom of mantle.
