An inverse tomographic problem of the construction of a 3-D velocity structure has been solved for depths of 10, 20, 30, and 40 km using the P-wave arrivals registered by the seismic array in southern Finland and on the DSS lines Sveka (1981) and Bal

SUMMARY The 430 km long DSS Baltic profile in SE Finland runs through the Rapakivi intrusion, the Svecokarelian geosynclinal complex, including the Ladoga-Bothnian Bay zone, and the Archean basement complex. A brief description of field operations in

Analogies are drawn between continental and continental margin structures on the basis of seismic data on the crustal structure of Eurasia and its Atlantic margins. Crustal thinning from the inner parts of the continent to its margins is observed to

Many geophysical characteristics of the Caspian and Black Seas' deep basins are similar, having: suboceanic type of the crust, low average seismic velocity, absence of earthquakes and relatively small variation of magnetic anomalies. However, the sed

The main results of seismic investigations in the transition zone from the Asian continent to the Pacific Ocean and in several regions of the Pacific Ocean are reported briefly. One of the most surprising findings is the existence of a layer with a P

A considerable body of data has been collected on the continental margins of the world but the greater part of these data are concentrated in a few areas and the remaining areas have received only limited attention. This is especially true of data de

Models are presented which illustrate the various methods used for the determination of the thickness and nature of deep seismic boundaries according to the observed amplitude and frequency of subcritical reflected waves. From this study it becomes c

Progress in different aspects of explosion seismology during the Upper Mantle Project period is discussed. In the method of field operation new observational systems have been developed, including continuous seismic depth-profiling, separate sounding
