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  Anisotropy of various magnetic parameters use for determining directions of material transfer in the study of turbidite currents
The carbonate clastic fans are considered as promising objects for oil and gas prospecting targets. Thus reconstruction of the fan morphology, sources and directions is an important practical task. The method for detecting the turbidite currents based on investigation of the anisotropy of susceptibility ellipsoids axes is described. The new model of main axes distribution is developed. Study of 13 objects allows us reconstructing directions of the turbidite currents of the Ural Foredeep for the two time-slices and draw maps demonstrating palaeogeographical position of the carbonate material sources.
Key words: anisotropy, magnetic susceptibility, turbidites, direction of material transfer, paleogeography, reconstruction, fan morphology, Ural Foredeep.

pdf  Deposits of the Devonian and Carboniferous boundary in the Kamenka River section (Pechora-Kozhvinsky megaswell, Timan-Pechora province)
The article deals with the Devonian/Carboniferous boundary in the shallow-water sequence (the Kamenka River section as example) on the basis of cyclostratigraphy (maximum of regression) controlled by biostratigraphical data (conodonts and foraminifers). Facial control on the foraminifer and conodont associations is considered. Dependence of the magnetic successibility of the rocks on the sea-level changes is detected. The dependence is probably caused by variations of the terrigenous content in the carbonate rocks.
Key words: Devonian/Carboniferous boundary, Timan-Pechora Province, conodonts, foraminifers, cyclostratigraphy, biostratigraphy, palaeomagnitology.

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.

New paleomagnetic method of borehole cores location determining
Geological study of large areas is based solely on the results of drilling. The relevance of such studies is obvious, as fields are very often found in closed areas. In such cases, the problem of sequence correlation of insufficiently faunistically characterized wells is common. Paleomagnetic (magnetostratigraphic) method is often the only method to enable such a correlation in these cases. However, it is necessary to find out the orientation of samples in the well in order to use paleomagnetic method. As for borehole cores, the orientation "top-bottom" is usually only known. The method that uses the direction of low-temperature (low-coercitive) modern viscous component of magnetization is applied in paleo-magnetism to orient the core samples to the cardinal. However, the possibilities of this method are limited for several reasons. We propose to use a new method that allows us to calculate the direction of the ancient magnetization components in those cases where conventional methods do not provide a satisfactory result. The new method was tested on the samples from two sequences of the Lower Vendian - Early Cambrian and one sequence of Cenozoic southeastern coastal of the White Sea area. The similarity of the results for natural outcrops and wells proves its high efficiency. The application of the new method has allowed us to calculate paleomagnetic poles for the Upper Vendian and Cenozoic Baltic as well as the age of reversal for the Late Vendian rocks. The alternative paleomagnetic poles for Vendian Baltic have been calculated through the results obtained and the reconstruction of paleogeographical position of the plate during the studied period of time has been made.
Key words: magnetostratigraphy, component composition of the rocks, Russian platform, correlation of geological sequences, core orientation.
