“…Previous investigations (Zhou and Thybo 1996;Yegorova et al 1999Yegorova et al , 2004Yegorova et al , 2007 have demonstrated that backstripping is a suitable method in regions where lithosphere is hidden under thicker sediments. Calculated residual anomalies (observed anomalies minus the effect of the backstripped layers) can be related to density heterogeneities in the underlying layers (although ''errors'' in parameterising the backstripped layers cannot be excluded).…”

The structure of the Glueckstadt Graben has been investigated by use of 3D gravity backstripping technique and by 2D gravity and magnetic modelling. Subtracting the gravity effects of the Meso-Cenozoic sediments together with Permian salt reveals a positive residual anomaly within the Glueckstadt Graben. This anomaly includes two local maxima over the Westholstein and Eastholstein Troughs. The 2D gravity models point to the presence of a high-density body within the lower crust of the Glueckstadt Graben. In addition, the results of 2D magnetic modelling indicate that the central part of the high-density body is overlain by an area with high susceptibility. Most probable, the formation of this high-density body is a result of complex poly-phase tectonic history of the study area. Finally, the results of gravity modelling indicate that Permian salt is not homogeneous. 3D gravity analysis and, especially, 2D gravity modelling have distinguished the differences in degree of salt saturation in salt-rich bodies, and elucidate the proportion of Rotliegend salt.

SUMMARY The European Plate has a 4.5 Gy long and complex tectonic history. This is reflected in the present‐day large‐scale crustal structures. A new digital Moho depth map is compiled from more than 250 data sets of individual seismic profiles, 3‐D models obtained by body and surface waves, receiver function results and maps of seismic and/or gravity data compilations. We have compiled the first digital, high‐resolution map of the Moho depth for the whole European Plate, extending from the mid‐Atlantic ridge in the west to the Ural Mountains in the east, and from the Mediterranean Sea in the south to the Barents Sea and Spitsbergen in the Arctic in the north. In general, three large domains within the European Plate crust are visible. The oldest Archean and Proterozoic crust has a thickness of 40–60 km, the continental Variscan and Alpine crust has a thickness of 20–40 km, and the youngest oceanic Atlantic crust has a thickness of 10–20 km.

“…Для Брагинского выступа характерен интенсивный позднедевонский вулканизм, о чем свидетельствуют верхнедевонские щелочно-базальтовые и щелочно-ультраосновные породы и их дифференциаты, достигающие мощности 3 км [Махнач и др., 2001]. Источник рифтогенеза, связанный с формированием ПДДВ, располагался под Прикаспийской впадиной и распространялся далее в северо-западном направлении с формированием рифтовой системы ПДДВ [Yegorova et al, 2004б]. Геометрия и структурные особенности ПДДВ определяются уже существовашей с докембрия сетью разломов и тектонических зон [Махнач и др., 2001;Yegorova et al, 2004а;Айзберг, Старчик, 2007;Гинтов, 2012;Пашкевич и др., 2014].…”
