An approach to the crustal velocities in southern China

The crustal architectures of southern China are examined by using the P-wave velocity values (Vp) acquired from synthesized geophysical profiles. The lithospheric crust may be divided, according to the Vp (values), into upper, middle and lower crust. The average velocity and thickness for individual crustal depths and for the whole crust are calculated respectively. All these data may assist in the research of the geodynamics of the Earth's internal architectures.
