(Федеральное государственное бюджетное образовательное учреждение высшего профессионального образования «Пермский государственный национальный исследовательский университет», 2018)24-26 ноября на базе Пермского государственного национального исследовательского университета состоялась I Международная научная конференция «Новые направления нефтегазовой геологии и геохимии. Развитие геологоразведочных ...
-
(2004)I-Xe analyses were carried out for chondrules and refractory inclusions from the two CV3 carbonaceous chondrites Mokoia and Vigarano (representing the oxidized and reduced subgroups, respectively). Although some degree of ...
-
(2003)A detailed record of sea surface temperatures in the Northern Hemisphere based on migration of marine invertebrate fauna (ammonites) and isotopic thermometry (δ18O values of shark tooth enamel) indicates a severe cooling ...
-
(2003)Ice cores from the relatively low-lying ice caps in Svalbard have not been widely exploited in climatic and environmental studies due to uncertainties about the effect of melt water percolation. However, results from two ...
-
(2003)The ice flow conditions of a 100 times 100 km area of Victoria Land, Antarctica were analyzed with the synthetic aperture radar (SAR) technique. The area includes a number of meteorite concentration sites, in particular ...

-
(1991)A Bathonian volcanogenic unit in northern Karabakh was examined. It was established that it belongs to a tholeiitic series of the ferruginous moderately highly titaniferous type. Two complexes were identified: an early ...
-
(2002)Cenozoic pelagic ('red') clays of predominantly eolian and hydrogenous origin blanket much of the central North Pacific ocean basin. The eolian component is a key indicator of past paleoclimatic conditions; thus, Cenozoic ...
-
(2006)Melliniite, ideally (Ni,Fe)4P, is a new mineral from the Northwest Africa 1054 acapulcoite. It occurs as anhedral to subhedral grains up to 100 μm, associated with kamacite and nickelphosphide. Melliniite is opaque with a ...
-
(2002)A new type of frambiodal pyrite, with icosahedral domains, is described in this study. Examining the microcrystals on sections of framboids from various localities using a scanning electron microscope, we found pentagonal ...
-
(2003)The Chernobyl accident in 1986 resulted in the widespread identification of the post-accident presence of radioactive (or 'hot') particles across large areas of Eastern and Central Europe. Such particles arise from direct ...
-
(2002)From the daily index Ap of geomagnetic activity, sequences of consecutive occurrence of Ap≤4 for four days and Ap≤7 for 8 days are identified in the period 1963-1998. A superposed epoch analysis is performed with the onset ...
-
(2003)Geological sedimentary dolomite samples from the Superior Proterozoic are studied using electron paramagnetic resonance (EPR) spectroscopy. The complex spectra in the g=2.0 region is composed of Mn2+ lines and signals due ...
-
(2001)We report the identification of a novel long-chain ketone in Holocene Black Sea sediments. Based on chemical properties, and chromatographic and mass spectrometric characteristics, this compound has been identified as a ...
-
(2013)Very few age controls exist for Quaternary deposits over the vast territory of the East Russian Arctic, which hampers dating of major environmental changes in this area and prevents their correlation to climatic changes ...
-
(2002)We present the selective ionization, resolution and identification of acidic NSO compounds in three crude oils of different geochemical origins by negative ion electrospray ionization (ESI) Fourier transform ion cyclotron ...
-
(2002)An urban fractured-rock aquifer system, where disposal of storm water is via 'soak holes' drilled directly into the top of fractured-rock basalt, has a highly dynamic nature where theories or knowledge to generate the model ...
-
(1988)We analyzed asphaltenes of crude oils and bitumens in dispersed organic matter from various regions of the West Siberian block and the Siberian craton. The West Siberian crude oil samples were collected from Jurassic and ...
-
(1989)Correlation of more than 1700 specific layered sections of the volcanic sequence in terms of their rhythmic stratigraphy has led to identification of lithological and stratigraphic intervals corresponding to formations, ...
