Description of Profiles,d by the recording of quarry blasts. The arrangement of the profiles is mainly determined by the distribution of these quarry blasts. Additionally some special seismic-refraction investigations were performed. The data of the recording points are presented in tables.impaction 发表于 2025-3-27 12:42:30
Standard Equipment for Deep-Seismic Sounding,agnetic tape. Each recording unit consists of three 2 cps-universal field seismometers, the corresponding amplifiers, modulators, the tape recorder and the time signal receiver. The signal frequency range is 0.3–100 cps..The high dynamic range of 60 db is reached by a very effective flutter and wowFLINT 发表于 2025-3-27 17:33:25

Problems of Evaluation of Seismic-Refraction Data for Crustal and Upper-Mantle Studies,data observed and ends with the display of a cross section which can reversely generate the primary observations. This procedure passes through several stages and it is quite evident that the final stage can be reached only in a more or less satisfactory approximation.
