-
(1987)To define regional patterns of change in the amplitudes of neotectonic movements, we constructed a chart of their average values (the averaging conditions were optimized by autocorrelation analysis). We analyzed the ...
-
(2001)The east Anatolian plateau and the Lesser Caucasus are characterised and shaped by three major structures: (1) NW- and NE-trending dextral to sinistral active strike-slip faults, (2) N-S to NNW-trending fissures and /or ...
-
(1992)Tylaites - feldspathic olivine clinopyroxenites from the Tagil'skiy dunite-clinopyroxenite massif in the platinum-bearing belt of the Urals - are of magmatic origin. They are composed of phenocrysts of zonal clinopyroxene, ...
-
(1989)Basanites (which mineralogically should be characterized by an abundance of plagioclase and only a little feldspathoid) and nephelinitic rocks (which normally lack modal plagioclase but should contain nepheline) are not ...
-
(2003)Из аптских отложений окрестностей с. Марьино описан ринхолит Hadrocheilus (Nerodenkoina) aenig-matosus subgen. et sp. nov.
-
(2001)Artificial Neural Network (ANN) models were used to forecast precipitation. Three-layer back propagation ANNs were trained with actual monthly precipitation data from six Czech and four Hungarian meteorological stations ...
-
(1996)Experimental studies of the metal/silicate partitioning of Ir have produced two sets of results differing by a factor of 106 (Jones and Drake, 1986; O'Neill et al., 1995). In an attempt to understand this discrepancy, we ...
-
(1989)The present array of tools for the geophysical investigations of oil wells is incapable of determining the liquid content (water or oil) of the rock pores in the conditions typical of wells of Western Siberia, which contain ...
-
(2002)Texture is defined as preferred crystallographic orientation in a polycrystalline aggregate. The main mechanisms of geological texture formation are crystallization, sedimentation, plastic deformation, recrystallization ...
-
(2001)The commissioning and operation of apparatus for neutron diffraction at simultaneous high temperatures and pressures is reported. The basic design is based on the Paris-Edinburgh cell using opposed anvils, with internal ...
-
(2004)We used the single-crystal sanidine laser fusion Ar-40/Ar-39 method to date five samples of volcanic rocks from the northern (Chukotka) part of the Cretaceous Okhotsk-Chukotka volcanic belt (northeastern Eurasia). Ages of ...
-
(2003)In 1998 and 1999, new aerogeophysical surveys of the Arctic Ocean's Eurasia Basin produced the first collocated gravity and magnetic measurements over the western half of the basin. These data increase the density and ...
-
(2004)The gold-quartz deposits of the Verkhnyaya Indigirka area of Yakutia formed during Mesozoic tectonogenesis, which was related to the collision between the Kolyma-Omolon composite terrain and North Asian craton at the end ...
-
(2004)Among the approximately 30 kimberlite fields discovered within the Siberian Craton, 25 make up the Yakutian kimberlite province. The study of the relationships between kimberlites and host rocks, fauna in xenoliths of the ...
-
(2001)Efficiency of optimal versions of computational schemes in algorithms for magnetic-induction monitoring of magnetite iron share in ores is grounded. Total iron share in ore is directly monitored on conveyers too. Fundamentally ...
-
(2002)The following new ammonite taxa are described: Dolganites, Longoceras, Platylongoceras, Transilongoceras, Platychamoussetia, Dolganites adzvensis, Longoceras raricostatum, Platylongoceras pechoicum, Transilongoceras ...
-
(2001)Two new ammonoid species Proplanulites (Proplanulites) irinae and P. (P.?) rogovi (the most recent known fossils that can be undoubtedly assigned to the subfamily Proplanulitinae) are described from the terminal enodatum ...
-
(2004)Six new ammonoid species, Dzhaprakoceras glabrum, D. angustum, D. flexiforme, Neopericyclus polaris, Hammatocyclus incertus, and Helicocyclus aberratus, are described from the Lower Carboniferous Beds on the Kozhim River. ...
