Digital processing of seismic data, which are registered on Transbaikalian part of reference geophysical profile 1-SB, is executed. These data are registered on CDP source-receiver configuration. Time sections images and wavefields of P- and S- head waves are result from technique of head waves dynamic conversion. These time sections are image a structure of refraction boundaries on the upper Earth crust on some areas of Argunskaya fold area, Mongol-Okhotsky fold belt, West-Stanovaya and Selengino-Yablonevaya fold areas. Seismic sections of depth interval of 0-2 km are constructed. Boundaries of intrusive body are detected on upper crust of Argunskaya fold area. This body is underlying lens shaped sedimentary layers on depth interval of 0.5÷1.0 km. Top of crystalline basement is established on the depth interval of 1.6-2.0 km on the northern part of Mongol-Okhotsky fold belt.
