(2004)Taphofloras of the Koryak Upland and the Sagwon Locality of North Alaska are described in terms of their taxonomic composition, stratigraphic ranges, and comparison with coeval floras of Northeastern Russia and Alaska. ...
-
(1995)MacFlinCor was developed to process laboratory data gathered on fluid inclusions and to calculate isochores for geologically important fluids composed of H2O, CO2, CH4, NaCl, and N2. Within the program, interactive diagrams ...
-
(1987)The recent additions to the lists of meteorite craters discovered on the Earth's surface are mainly impact-induced structures over 1 to 3 km in diameter [1-3]. This paper describes the identification and study of another ...
-
(Федеральное государственное бюджетное учреждение науки Геофизический центр Российской академии наук, 2019)Inter-well measurements are used to reduce drilling costs with no reduce small kimberlite body detection. The radio wave method enables measurement of the apparent absorption coefficient that is proportional to the effective ...
-
(2003)The isotopic composition of carbon and oxygen was determined by two techniques in whole-rock samples and single grains of carbonates from rocks of various morphogenetic types from the Aldan Shield. The isotopic values ...

(2004)Euhedral macrocrystals of Pt-Fe alloy from the Kondyor PGE placer, Khabarovskiy Kray, eastern Siberia, Russia, have a relatively constant composition of Pt2.4-2.6Fe, tin and antimony contents up to 0.3 wt.%, and an unusually ...
-
(2001)A new class of cyclic hydrocarbon biomarker, macrocyclic-alkanes and their methylated analogues, have for the first time been unambiguously identified in a Botryococcus braunii rich sediment (torbanite). The compounds, ...
-
(2004)We present a detailed study of Re-Os age determinations for eight natural molybdenite samples of like polytype (2H), spanning a range of age, natural grain size and deposit type. The focus of the study is to critically ...
-
(2001)A general analysis of electroosmotic phenomena is given for random porous media through which an electrolyte flows. A dimensional analysis demonstrates the crucial importance of the dimensionless coupling parameter a, which ...
-
(2006)Modern concept of seismic hazard assessment is based on the assumption that what was observed in the past could likely be expected in the future. It could be easily recognized by comparison of spatial distribution of maximum ...
-
(2002)The Salsk, 22 May 2001, earthquake occurred within the Russian platform in almost aseismic area. Its magnitude (MS = 4.6) is the largest instrumentally recorded one in the region. This makes the event of a crucial importance ...
-
(2006)The geological record is a three-dimensional mosaic of gap-bound rock bodies that, at any given scale of temporal resolution, were emplaced more or less continuously. At any geographic location, the irregular alternation ...
-
(1988)The island arc-type association of plutonic inclusions in Kamchatka is represented most completely on the Avacha and the Shiveluch volcanoes. While studying Late Cenozoic volcanism on the Valovayam River, Kamchatka Isthmus, ...
-
(2006)Mafic and ultramafic xenoliths are well represented within a large basaltic lava field of Stromboli. These basalts, known as San Bartolo lavas, show a high-K calc-alkaline (HKCA) affinity and were erupted <5 ka BP. Xenoliths ...
-
(2006)Geochemical and geochronological studies reveal three distinct groups of Neoproterozoic to Early Paleozoic mafic intrusions in the Biryusa metamorphic massif of southwestern Siberia. Group 1 includes mafic sills that ...
-
(2007)A 3D velocity model of the Earth's crust beneath the Klyuchevskoy volcanic group has been constructed using the seismic tomography method. Anomalies of the velocity parameters related to the zones of magma supply to active ...
-
(2006)Compositional, textural and experimental data on products from explosive and effusive eruptions of Neapolitan volcanoes (Campi Flegrei and Somma-Vesuvio) allow us to constrain degassing and fragmentation conditions during ...
