A.A. Predovsky, I.V. Chickiryov, D.A. Nekipelov MAIN FEATURES OF AULOCOGENES , SYNCLINE TROUGHS AND DEPRESSIONS IN CONNECTION W ITH THE PROBLEM OF TYPOLOGY OF CRUST STRUCTURES The study is based on the model o f m antle-crust interaction and on m orphostructural analysis. The formation features o f synform crust structures (aulocogenes, linear syncline troughs and depressions) are characterized. It is shown tha t the ruling factors o f the process are the activated long-living deep lineament zones (DLZ). Keywords: mantle-crust interaction, aulocogenes, troughs, depressions, typology of crust structures. N.N. Melnikov, V.P. Konukhin, V.A. Naumov, S.A. Gusak, A.V. Naumov, E.V. Karavayeva STUDY OF LONG -LIVED RAD IONUCLIDES ACCUMULATION IN THE CORES OF REACTOR FAC ILIT IES OF NUCLEAR ICEBREAKERS The article contains a b rie f description o f the problem related to nuclear and radiation-hazardous facilities dism antling at the fo rm e r coastal bases o f Northern Fleet and the floating technical bases (FTB) of the nuclear icebreakers flee t located in the Kola Peninsula. The paper presents the methodology and main results o f study o f long-lived radionuclides accumulation in the reactor cores o f “Lenin”, “A rctica ” and “S ib ir” nuclear icebreakers, o f which the spent nuclear fuel (SNF) was reloaded into the FTB “Lepse” during the period from 1963 to 1981. Based on the study results, the assessment has been carried out o f а- и p- activity o f SNF in the “Lepse” storage fa cility at present period o f time. Keywords: radiation-hazardous facilities, nuclear icebreakers, dismantling, spent nuclear fuel, long- lived radionuclides. S .I. P echen yuk INVESTIGATION OF SORPTION PROPERTIES OF METALS AMORPHOUS OXYHYDROXIDES W ITH REGARD TO AN IONS The main results o f system atical fundamental research o f anions tha t are environm ent pollutants (arsenate, phosphate, oxalate) w ith amorphous oxyhydroxides o f iron, zirconium , alum inium and chrom ium are briefly expounded. The sorption mechanisms are presented in the light o f the modern view on the interaction o f ions w ith an e lectrica lly charged surface and the form ation o f sorption complexes. Keywords: sorption, sorption complex, surface charge, sorption isotherm, extraction, sorption mechanism, point of zero charge. E.D. Tereshchenko, V.F. Grigoriev, P.E. Tereshchenko, R.Yu. Yurik THE EFFECT OF FAULTING ON THE STRUCTURE OF THE NATURAL MAGNETIC FIELD IN THE KO LA BAY The results o f simultaneous studies o f electrom agnetic noise on the bottom o f the Kola Bay and on the island near point o f the equipment dipping, as well as at the observatory, located at a considerable distance from the place o f measurements in the bay are presented. It is presented the description o f the equipment used in the experim ent which includes: an upgraded receiving equipment o f the marine receiving and transm itting complex, the electrom agnetic fields mobile and stationary meters. It is shown the e ffect of faulting on the structure o f the natural magnetic field, which leads to the ve rtical component enhancement in the bay.

K o rn ilo v THEM IS OBSERVATIONS OF THREE S IM ILAR D IPOLAR IZAT ION EVENTS During one-hour tim e interval (11.02.2008, 00:00-01:15 UT) THEM IS spacecraft (X=-6 Re, Y=4 Re) detected three almost identical dipolarization events coupled w ith ve ry sim ilar auroral activity of pseudobreakup type and rather d ifferen t dispersionless particle injections. In the firs t event, both electron and proton spectra are strongly oscillating (period about 2.5 m inutes) and anticorrelating. Electron spectrum also demonstrates anticorrelation o f electron fluxes w ith energies 10­ 500 eV and 2-20 keV correspondingly, so in this case all electrons are accelerated from the local cold plasma background by some active processes at the fron t o f dipolarization wave, and in this case dipolarization is a primary event. In the second event, electron fluxes were sharply increased w ithout noticeable changes in electrons energy. Fine details o f dipolarization (Bz components variations) fo r several seconds delayed o f electron flux variations, so we can suppose tha t dipolarization is a secondary process. In the third event, there was no substantial changes in the to ta l electron flux, but the average electron energy increased from 2 keV up to 12 keV. 104
