Crustal and Uppermost Mantle Structure in the Pacific, North American, and Eurasian Plate Junction

摘要

Investigations of the crustal and uppermost mantle structure have always required high finance input, especially in marine basins. Methods of seismic sounding have always led in studies of the velocity structure. The method of deep seismic sounding (DSS) allows us to reveal the structure of the velocity at least to the depths of the basement of the Earth's crust [1 -3]. The converted wave method with common depth point (CWM CDP) is limited to even smaller depths [4, 5].
