The Structure of the Earth's Crust and Uppermost Mantle along the Baikal Rift System Based on Teleseismic Data

摘要

Detailed data on the velocity structure of the Earth's crust and uppermost mantle are very important to study the complex structure of the Baikal rift system. Such data can be obtained not only from deep seismic sounding (DSS) but also on the basis of the teleseismic method of P-wave receiver function (P-to-S). The analysis of the wave forms in this method is based on the approach of seismic prospecting using the records of strong distant earthquakes [1, 2]. Owing to the sensitivity of converted shear seismic waves to velocity inhomogeneities at different depths, this method gave good results in the study of the velocity structure based on the records of temporary stations in the south of Siberia and in Mongolia [3, 4].
