Travel-Time Curve and Structure of the Earth's Crust in Central Asia According to Recordings of Powerful Explosions

摘要

The present study sets forth the preliminary results of a study dealing with the velocities of propagation of elastic waves and the structure of the earth's crust in Central Asia, based on a travel-time curve constructed according to data from recordings of powerful explosions. The velocities obtained from analysis of the travel-time curve differ little from the velocities obtained earlier by E. A. Rozova. The structure of the earth's crust in the first approximation can be represented in the following form: layer of sedimentary rocks, 5 km +- 1 km; granitic layer, 15 km +- 5 km; basaltic layer, 30 km +- 10 km; and total thickness of earth's crust, 50 km +- 10 km.
