RESEARCH TARGET

Distributions of seamounts, oceanic plateaus and guyots on the Pacific Plate.

These volcanic edifices might reach to the Pacific rim in the future.
Present seafloor, below the deep deep ocean, of the western Pacific records much informations of volcanic activities & tectonic events after Early Cretaceous. So my research target is the origin of basalts from the seamounts on the Pacific plate using:
1) Petrology
2) Geochemistry
3) Radiometric age by the Ar-Ar & U,Th-Pb dating
4) Mode of occurrence

5) Bathymetry & Geology
6) Kinematics and behavior of the Pacific plate
