pdf Upper Devonian (Frasnian stage) of the north-western part of the Russian Platform: paleomagnetic data
Paleomagnetic determinations for the Devonian strata of the Main Devonian Field, available in the international paleomagnetic data base, do not make it possible to construct both detailed magnetostratigraphic scales and reliable trajectories of the apparent polar wander path of the paleomagnetic pole. This is primarily due to the insufficient amount of data that determine modern reliability criteria. Obtaining more complete series of reliable paleomagnetic determinations is one of the important tasks of paleomagnetic studies. The paper presents new paleomagnetic determinations from a collection of rocks of the Frasnian stage of the Upper Devonian (Ilmen and Bureg Beds of the Semiluky Formation), sampled on the southern shore of Lake Ilmen, east of the village. Korostyn in 2009. Magnetomineralogical studies were carried out to determine the magnetic minerals of carriers of natural remanent magnetization. Three characteristic components of natural remanent magnetization have been identified. Two components correspond to the Late Paleozoic magnetization reversal (in the Carboniferous and Permian times). The third, bipolar component of the Frasnian age passes the reverse polarity test of the geomagnetic field.. The obtained position of the paleomagnetic pole by the bipolar component of the natural remanent magnetization is consistent with the available data on the section of the Late Upper Devonian of the Main Devonian Field.

Keywords: paleomagnetism, Frasnian stage of the Upper Devonian, Ilmen and Bureg Beds of the Semiluky Formation, geomagnetic field polarity, magnetostratigraphy, paleomagnetic pole.

pdf Magnetostratigraphy of Early Devonian deposits of Spitsbergen
A new paleomagnetic results on the collections of the Early Devonian rocks from the northern part of the Spitsbergen land are presented. Detailed demagnetization of the еarly Devonian rocks reveals the presence of two components of the natural remanent magnetization. The zones of normal and reverse polarity are identified in our study for the Andreebreen, Fraenkelryggen and Ben Nevis Formations, Red Bay series and Kapp Kjeldsen and Keltiefjellet formations, Wood Bay series. The polarity and reversal tests for components of normal and reverse polarity is positive. Directions of paleomagnetic poles for early Devonian time are consistent with the available data on Spitsbergen. The reasonable correspondence between the locations of the zones of normal and reverse polarity revealed in our study and the general magnetostratigraphic scale support the old age of the isolated characteristic components of normal and reverse polarity.

Keywords: the polarity of the geomagnetic field, magnetostratigraphy, paleomagnetic poles, Spitsbergen.

pdf  Paleomagnetic research of the Paleozoic sections of Polar Urals (Paga River)
Paleomagnetic studying of Cambrian-Ordovician-Devonian collection of Paleozoic deposits of the Paga River valley has been carried out. The results of paleomagnetic research show a two-component structure of natural residual magnetization (NRM). The identified typical components are postfolded. The estimates of horizontal turns of structures are executed. The possible model of magnetic reversal of the studied deposits has been realized.

Keywords: paleomagnetic vectors, anisotropy of magnetic susceptibility, overthrust, Polar Urals.

pdf  Palaeomagnetism of sedimentary rocks of the South Uralian Asha series: new data
Collection of rock samples from the Kuk-Karauk and Basa Formations of the Upper Vendian Asha series on the Basu River, Zilim River and Kuk-Karauk Stream have been studied. Multicomponent structures of the studied rocks magnetization have been identified. Component ages have been estimated by comparison with the data for the East-European plate. The results allow us to trace and to date the main stages of the tectonic history of the belt placed along the western side of the Main Uralian thrust.

pdf  Upper Devonian - Lower Carboniferous succession, Kostyanoy Cape, Vaygach Island
Results of multidisciplinary study of the Upper Devonian – Lower Carboniferous succession of the NE of the Vaygach Island are described. T-R cycles, biostratigraphical units based on foraminifers and conodonts, and magnitostratigraphic zones have been identified in the section for a first time. Due to complete carbonate succession of the Middle Famennian – Upper Visean, the section is considered as a key one of the NW of the Pay-Khoy – Vaygach region and the east of Barents Sea shelf.
Key words: stratigraphy, Upper Devonian, Lower Carboniferous, Foraminifera, Conodonta, palaeomagnetism, Vaygach Island.

pdf  To the history of thrust structures of the Pai-Khoi and Polar Urals: paleomagnetic data for Early Permian and early triassic sediments
Collection of Early Permian rocks (P1gs, artinskian stage, section r. Yabtoyakha (Gusinaya), south-west of the Pai-Khoi have been studied. Analysis of the inferred new and published paleomagnetic data for the fortland structures of the Polar Urals and Pai-Khoi showed that horizontal orientation of paleomagnetic directions reflect the clockwise and counterclockwise rotations of the these structures consequently. Values of these rotation angles and total thrust amplitudes for the Pai-Khoi structures are estimated.

Key words: paleomagnetic directions, geodynamic, collision, thrust, Pai-Khoi.

pdf Upper Devonian - Lower Carboniferous key sequence on the Talota river, Timan-Pechora province - results of lithologic, biostratigraphic and paleomagnetic researches
The results of complex studying the Upper Devonian - Lower Carboniferous key sequence on the Talota river (north of the Vashutkino-Talota zone of overthrusts, Timan-Pechora province) are presented. The tectonic twinning of the sequence on the zone of overthrusts is proved by biostratigraphy data. The parautochthonous and allochthonous parts of the sequence are dated by foraminifera and conodonts. The first part contains Early Famenian-Late Visean deposits, the second part - Late Famenian-Serpukhovsk deposits. Breaks in sedimentations are established in the Lower Tournaisian and Lower Visean. The presence of an ancient secondary prefolded component of magnetization, confined to the definite parts of the sequence and caused by tectonic and hypergene processes, is established. The direction of this magnetization allowed reconstructing the prefolded (Middle Paleozoic) position of the allochthone and parautochthone.
Key words: Upper Devonian, Lower Carboniferous, key sequence, Timan-Pechora province, stratigraphy, paleomagnetology, tectonics.
