The deepest hole in the world being drilled at the Kola well has now penetrated about halfway through the crust of the Baltic continental shield, exposing rocks . Abramovitz, T., Berthelsen, A. & Thybo, H. Proterozoic sutures and terranes in the southeastern Baltic Shield interpreted from BABEL deep seismic data. Tectonophysics , .
A number of papers from studies performed as a part of CARA (Charpentier & Gautier) are included in this volume, as are a number of studies of the Russian Arctic, in particular its shelf areas (Grigorenko et al.; Kaminsky et al.; Kontorovich et al.). As a result, this book can present a relatively complete view of Arctic petroleum geology. Obtaining high fidelity seismic images in deep water basins has several challenges. These run from the issues of dealing with noise to building accurate interval velocity models for Pre-Stack Depth Migration (PreSDM). Exploration, and development, in such basins is commonly associated with deep.
Key results from the BEAR (Baltic Electromagnetic Array Research) soundings and the SVEKALAPKO Seismic Tomography Experiment (SSTE), which explored geophysical properties of the upper mantle beneath the Fennoscandian Shield, are summarized here. These two projects formed the two key geophysical experiments in EUROPROBE's SVEKALAPKO project. The major result obtained from . This comprehensive book deals primarily with reflection seismic data in the hydrocarbon industry. It brings together seismic examples from North and South America, Africa, Europe, Asia and Australia and features contributions from eleven international authors who are experts in their field. It provides structural geological examples with full-color illustrations and explanations so that.

Integrated Seismic Studies of the Baltic Shield Using Data in the Gulf of Bothnia Region will produce better velocity models of the crust and better constrained contour maps of crustal thickness in this part of the Baltic shield.

Uppsala University, Disciplinary Domain of Science and Technology, Earth Sciences, Department of Geophysics. deep seismic data were acquired along profile lines that cross the border zone between the undeformed Baltic Shield and the accreted continents.
The controlled source seismic study [also known as the deep seismic sounding (DSS) study] is a definitive geophysical technique for exploring the structure of the Earth's crust and uppermost mantle. It is a highly sophisticated technique involving use of controlled explosions, of known energy release, to generate elastic waves in the Earth's crust.
In the shield part of the profiles northeast of the Sorgenfrei-Tornquist Zone, crustal reflectivity is observed at all levels and its termination in depth coincides largely with the crust-mantle boundary. the wide-angle data indicate a three-layer crust with velocities of –, circaand – km s −1.
the Moho is found between. The lithospheric models obtained for the Baltic Shield by using deep seismic soundings are discussed and results from different parts of the shield are compared with models achieved by the investigation of surface waves and of P to S converted waves.
The results are found to agree rather well with each other particularly with regard to the first interface (at a depth of 10–15 km) and the.
We review the results of the TopoScandiaDeep project, a component of the TOPOEUROPE project, in which we have studied the crustal and upper mantle structures of southern Norway in relation to its high topography. The Scandinavian Mountain Chain (the Scandes) is an intracontinental mountain chain at the western edge of the Baltic shield, and has its southern part located in southern Norway.

North China is an Archean-Paleoproterozoic craton (), and its western part in particular retains its cratonic nature with a thick lithospheric mantle (~ km) and crust [~42 km ()] and a seismically slow lower crust [V p = ~ km s −1 ()] ().On the northern margin of the western North China craton, a ~Ga-old ophiolitic mélange and >Ga-old.
In –, researchers of the IO RAS conducted seismological observations in the Baltic Sea and western Kaliningrad region with the use of ocean-bottom and land-based autonomous seismic stations.
According to maps of general seismic zoning of the territory of Russia, the Kaliningrad region is aseismic. However, a series of seismic phenomena with magnitudes of about 5 and sources.

The STZ, trending NW extends from the island of Bornholm across the northeaster part of Denmark to the Skagerrak, with Precambrian Baltic Shield to the northeast and deep sedimentary basins to the southwest. Multidisciplinary geophysical studies reveal marked contrasts in crustal and upper-mantle structure across the STZ.
transition zone. This study provides the ﬁrst map of the mantle transition zone below Fennoscandia, which will be valuable for any further global studies of the mantle transition zone.

Depending on the context the Baltic region might stand for. The countries that have shorelines along the Baltic Sea: Denmark, Estonia, Latvia, Finland, Germany, Lithuania, Poland, Russia, and Sweden. The group of countries presently referred to by the shorthand Baltic states: Estonia, Latvia, and Lithuania.
Estonia, Latvia, Lithuania and Kaliningrad Oblast of Russia. The stated areas of study were the deep structure of the Baltic Shield, seismic discontinuities and the thermal regime in the Earth's crust, the physical and chemical composition of the deep crust and the transition from upper to lower crust, lithospheric geophysics, and to create and develop technologies for deep geophysical study.

In addition, seismic events occurring in the western part of the Murmansk block in and with a magnitude of and are described, respectively (Ahjos and Uski.

Integrated seismic studies of the Baltic shield using data in the Gulf of Bothnia region. a contrast to the usual non-reflective plutons elsewhere in western Europe. Additional dipping reflections deep in the crust of this area may support models of rifting and crustal thinning during emplacement of the Ga Rapakivi granites.
The wide-angle data is of very high quality due to the low noise and good transmission of seismic energy through the cratonic crust of the Baltic Shield. BABEL line 6 is a km long, north-south profile in the western half of the Sea of Bothnia that runs almost parallel to several deep seismic refraction profiles previously acquired in Sweden.Seismic belt, narrow geographic zone on the Earth’s surface along which most earthquake activity occurs.
The outermost layer of the Earth (lithosphere) is made up of several large tectonic plates. The edges where these plates move against one another are the location of interplate earthquakes that produce the seismic belts.The Scandinavian Mountain Chain (the Scandes) is an intracontinental mountain chain at the western edge of the Baltic shield, and has its southern part located in southern Norway.
The timing as well as the processes causing the formation of the Scandes are disputed.
