-
(2004)The separation of paramagnetic and ferromagnetic anisotropy of magnetic susceptibility (AMS) is achieved in this study by using a vibrating sample magnetometer and a torque magnetometer performing directional anisotropy ...
-
(1996)We present results of static lattice energy and vibrational energy calculations for the 12 garnet end-members in the system (Ca,Mg,Mn,FeMAl,Cr,Fe)2Si3012' The structure of the end-member phases was first simulated with the ...
-
(2001)The methods of parameterization of sub-grid effects and their effectiveness are investigated using a distributed physically-based model of the hydrological cycle for two river basins situated in the steppe-forest zone of ...
-
(2002)In the monitoring of local seismicity the occurrence of many explosions poses two types of severe practical problems: (1) Such recordings add significantly to the analyst's workload, and (2) in extreme cases they pollute ...
-
(2003)Shortly after his appointment to the first geophysical professorship (1895 at the Jagiellonian University of Cracow), Rudzki had published two papers in which he made a strong case for anisotropy of crustal rocks [Beitr. ...
-
(2001)The parametrized shooting method is extended to 3-D seismic ray tracing in a spherical earth with discontinuities. A shooting vector at a seismic source is iteratively updated by using numerical integrals of several variables ...
-
(2003)На основе изучения онтогенеза раковин рода Tumaroceras из его состава выделен новый род Paratu-maroceras с типовым видом P. ruzhencevi sp. nov. Приведено описание новых таксонов.
-
(2003)Based on the ontogeny of the genus Tumaroceras, a new genus Paratumaroceras, with the type species P. ruzhencevi sp. nov., is proposed. New taxa are described.
-
(2004)По находке черепа на местонахождении Баин-Дзак (Монголия) описана ископаемая ящерица Parauromastyx gilmorei gen. et sp. nov. Наряду с позднемеловым Isodontosaurus gracilis Gilmore, 1943 и рядом проблематичных палеогеновых ...
-
(2004)A new Late Cretaceous lizard, Parauromastyx gilmorei gen. et sp. nov., is described on the basis of a skull from the Bayn-Dzak locality (Mongolia). The new lizard along with Late Cretaceous Isodontosaurus gracilis Gilmore, ...
-
(2003)Paravinogradovite is a new mineral species from Mount Kukisvumchorr, Khibina alkaline massif, Kola Peninsula, Russia. Paravinogradovite forms prismatic crystals elongate along [100] and up to 0.5-1.0 cm long; crystals in ...
-
(2003)The first footprints and tracks of large terrestrial reptiles were discovered in the Late Tatarian deposits in northem European Russia. The tracks were found in light gray thick-bedded limestone of the Upper Tatarian ...
-
(1996)The melt portion of a parental magma, undergoing equilibrium olivine crystallization, passes through a succession of compositions unique to its initial composition. Because the succession of compositions follows uniquely ...
-
(2001)Equilibrium melt trace element contents are calculated from Proterozoic Nain Plutonic Suite (NPS) mafic and anorthositic cumulates, and from plagioclase and orthopyroxene megacrysts. Assumed trapped melt fractions (TMF) ...
-
(2002)A key element in the solution of a geophysical inverse problem is the quantification of non-uniqueness, that is, how much parameters of an inferred earth model can vary while fitting a set of measurements. A widely used ...
-
(2002)We have tested the additivity of partial anhysteretic remanent magnetization (pARM) for suites of eight synthetic magnetites with mean grain sizes from 65 nm to 18 mm and 18 natural samples including lake sediments, oceanic ...
-
(2002)One necessary condition for successful determination of relative paleomagnetic field intensity using anhysteretic remanent magnetization (ARM) methods is reciprocity: a partial ARM, produced by a steady field H applied ...
