    In:  Supplement to: Fedorov, P I; Kovalenko, D V; Ageeva, O A (2011): Western Kamchatka-Koryak continental margin volcanogenic belt: Age, composition, and sources. Translated from Geokhimiya, 2011, 49(8), 813-838, Geochemistry International, 49(8), 768-792, https://doi.org/10.1134/S0016702911060036

    Description: An isotope-geochemical study of Eocene-Oligocene magmatic rocks from the Western Kamchatka-Koryak volcanogenic belt revealed lateral heterogeneity of mantle magma sources in its segments: Western Kamchatka, Central Koryak, and Northern Koryak ones. In the Western Kamchatka segment magmatic melts were generated from isotopically heterogeneous (depleted and/or insignificantly enriched) mantle sources significantly contaminated by quartz-feldspathic sialic sediments; higher 87Sr/86Sr (0.70429-0.70564) and lower 143Nd/144Nd [eNd(T) = 0.06-2.9] ratios in volcanic rocks from the Central Koryak segment presumably reflect contribution of an enriched mantle source; high positive eNd(T) and low 87Sr/86Sr ratios in magmatic rocks from the Northern Koryak segment area indicate their derivation from an isotopically depleted mantle source without significant contamination by sialic or mantle material enriched in radiogenic Sr and Nd. Significantly different contamination histories of Eocene-Oligocene mantle magmas in Kamchatka and Koryakia are related to their different thermal regimes: higher heat flow beneath Kamchatka led to crustal melting and contamination of mantle suprasubduction magmas by crustal melts. Cessation of suprasubduction volcanism in the Western Kamchatka segment of the continental margin belt was possibly related to accretion of the Achaivayam-Valagin terrane 40 Ma ago, whereas suprasubduction activity in the Koryak segment stopped due to closure of the Ukelayat basin in Oligocene.

    Description: In September 2000 we carried out a comprehensive study of dynamics of water and suspension in the area south of the Chupa Bay adjacent to the Keret' Archipelago and the estuary of the Keret' River (Karelian coast of the White Sea) onboard R/V Ekolog. The entire study area can be divided into three estuary zones characterized by different dynamic regimes: marine, intermediate, and near-mouth zones. Autumn stratification of the water column is particularly distinct in the most dynamic marine zone. The strongest mixing of the upper layer is also observed in the marine zone. The most intensive dilution and the largest thickness of the diluted water layer are found in the near-mouth zone. On the whole in the near-mouth zone concentration of suspended matter is higher than in the intermediate and marine zones. The highest phytoplankton abundance is observed in the marine zone, whereas the lowest one is confined to the near-mouth zone. At all the stations both abundance and biomass of flagellates dominate.

    Notes: Abstract— The use of linear elastic fracture mechanics to describe the kinetics of fatigue fracture of welded joints with high welding residual stresses (WRS) is experimentally evaluated in this paper. A correction analysis is used to show that the crack propagation rate of cracks in joints, as a function of the applied stress intensity factor, is linear on a log-log scale in the Paris regime when non-uniform fields of WRS are superimposed on the applied cyclic loading. It is shown that crack growth rates in joints with high WRS do not depend on the characteristics of the loading cycle. The parameters of the Paris exponential equation are determined by the initial WRS distribution, by the range of cyclic stresses and by the load ratio. A method for calculating the cyclic crack resistance of joints is proposed which explicitly allows for a non-uniform field of WRS that influences the fatigue crack growth rate.
