c o n t e n t s NATURAL AND TECHNICAL SCIENCES Gershenkop А ^ К , Hohulya М..S., Mukh ina Т .К TECHNOGENIC RAW MATERIAL PROCESSING IN THE KOLA PENINSULA Murmansk region is notable for its developed mining industry. There are several operating processing plants working with copper-nickel, apatite-nepheline, apatite-magnetite, iron and mica ores, rare metal ores; there are wastes o f some billion tons stockpiled in active and conserved tailing ponds. Moreover there are overburden rock dumps. This results in large technogenic deposits with stockpiled mined out raw materials, for the most part already beneficated. The paper shows possibilities of obtaining various concentrates from technogenic raw materials o f operating mining enterprises and directions o f its possible utilization. Keywords: techogenic raw materials, benefication, comprehensive use, flotation, gravity, magnetic and electric separation, concentrates, utilization Savchenko S.N., Kozyrev A.A. ABSTRACT TO THE ARTICLE ROCK STRESS STATE IN SYSTEM “FAULT - BARRIER - FAULT” The regularities o f stress-strained state formation for rock mass with various joint system have been studied based on numerical (finite element method) and physical (using equivalent material) modelling. There have been established the peculiarities o f destruction o f barrier zones that divide fractures. Keywords: stress, rock mass, faulting, barrier zone Urbanavichus G.P. BIOGEOGRAPHIC REVIEW OF LICHENS DIVERSITY OF THE MURMANSK REGION 1175 species of lichens, non-lichenized lichenicolous and allied saprophytic fungi was found in the Murmansk Region. The biological, geographical and systematic of lichen flora data are summarized. Key bounds of distribution of lichens on the Kola Peninsula and adjacent territories are present. The most part of lichen flora (more than 70% of species composition) are species with circumpolar and circumboreal ranges. Estimate of the occurrence in the Murmansk Region about 1500-1600 species of lichens is given by on analysis of lichens geography and diversity in the Northern Europe. Collema subnigrescens Degel. and lichenicolous species Dactylospora glaucomarioides (Willey ex Tuck.) Hafellner, Phacographa glaucomaria (Nyl.) Hafellner, and Stigmidium pumilum (Lettau) Matzer & Hafellner are reported for the first time for the Murmansk Region. Keywords: lichens, diversity, biogeography, Murmansk Region Kuklin V. V. MULTIYEAR STUDIES OF FAUNA AND ECOLOGY OF PARASITES OF THE BARENTS SEA BIRDS AND INTERRELATIONS IN THE “HELMINTHS-SEA BIRDS” SYSTEM The data on composition, ecology and dynamics of the helminthfauna o f birds o f the Barents Sea by results o f parasitological researches carried out in 1991-2009 in Murman Coast, Novaya Zemlya, Franz Josef Land and Spitsbergen are generalized. The peculiarities o f helminthes fauna composition o f birds in different parts o f the Barents Sea is traced. Besides, local differences in the degree o f infection by helminths o f some bird species in the East Murman are described. On the example o f the Seven Islands Archipelago the analysis of long-term changes o f helminthfauna of birds by results o f comparison o f the current materials with data of the analogous investigations carried out o f M.M. Belopolskaya in 1940-1941. By results o f researches o f the gulls, genus Lams, the main tendencies in seasonal dynamics o f helminthfauna of birds in the spring-autumn period are determined. On the basis o f the results o f both field and experimental investigations the problems of infection by helminthes impact on the metabolism parameters in the seabirds are investigated, peculiarities of biochemical processes in the organisms o f the final host at the development o f the cestode and trematode invasion are determined. The further prospects of parasitological studies of the birds of the Barents Sea are also determined. Keywords: helminths, seabirds, seasonal and long-term dynamics, biochemical parameters, host- parasiteinteraction 142
