(2006)The tonalite-plagiogranite (tonalite-trondhjemite) association only occasionally occurs in the form of large granitoid bodies, such as the Yenisei Batholith (>500 km2 in area). The granitoids of the Yenisei Batholith belong ...
-
(2006)Two new monotypic genera and a new monotypic family Rozanovicystidae of the class Cincta are described from the Middle Cambrian (Mayaktakh Formation) of the northeastern part of the Siberian Platform. Based on data obtained ...
-
(2006)Three stages of Early Proterozoic granitoid magmatism were distinguished in the southwestern margin of the Siberian craton: (1) syncollisional, including the formation of migmatites and granites in the border zone of the ...
-
(2006)A new dicynodont genus and species, Idelesaurus tataricus sp. nov. (Cryptodontidae), from the Semin Ovrag locality (Tatarstan, Tetyushinskii District; Upper Permian, Upper Tatarian Substage, Severodvinian Horizon) is ...
-
(2006)A new genus Siberioklipsteinia (with the type species S. dagysi sp. nov.) and a new species Arctoarpadites nelgesensis are described from the Carnian of the Kharaulakh Range and Yana Upland (eastern Yakutia). The new data ...
-
(2006)The Kalguty ore-magmatic system comprises two intrusive complexes: the Kalguty granite-leucogranite complex and Eastern Kalguty complex of dikes and small intrusions. U-Pb dating of individual zircon grains from granites ...
-
(2006)Devonian brachiopod shells from North America, Spain, Morocco, Siberia, China and Germany were analysed for δ13C, δ18O and 87Sr/86Sr. The samples were screened for diagenetic alteration by means of cathodoluminescence, ...
-
(2006)Reassessment of the suite of specimens used by William King when he erected the fenestrate bryozoan genus Thamniscus in 1849 has shown that they belong to two genera. However, King's original generic concept only allows ...
-
(2006)A mechanism of ULF geomagnetic field perturbations caused by rock fracture and tectonic activity is studied. It is assumed that the rock fracture is accompanied by crack-generated seismic emission due to cracks pile up at ...
-
(2006)A number of experimental evidences have recently been obtained for existence of stable anomalies of infra-red outgoing Earth radiation in seismo-active regions, basically by using NOAA-series satellite data. A theoretical ...
-
(2006)Directions, modes, specializations, and coordination systems of morphofunctional changes are discussed based on modern data. Phylogenetic heterochronies (pedomorphoses and outstripping), which provide the basis for parallel, ...
-
(2006)The products of shock metamorphism in the Jänisjärvi astrobleme in Karelia, Russia, are compared with the results of experiments in which spherical converging shock waves affected a spherical rock sample. The sample was ...
-
(2006)The dynamics of the taxonomic diversification of normal-marine bivalve mollusks and that of the entire fossil marine skeletal fauna are compared. A major Early Permian turnover has been revealed. The changes in the proportions ...
-
(2006)This paper presents the results of the integrated study of dinocysts and diatoms from the Kamyshin Formation, Dyupa Gully section. The Kamyshin Formation is shown to have been formed in the Late Thanetian-initial Eocene ...
-
(2006)The current state of the North Pacific Cenozoic diatom zonation is reviewed. The high resolution of diatom zonation is shown, which is comparable to that of groups of calcareous planktonic microfossils. The significance ...
-
(2006)The paper presents newly obtained data on the geological structure, age, and composition of the Gremyakha-Vyrmes Massif, which consists of rocks of the ultrabasic, granitoid, and foidolite series. According to the results ...
-
(2006)Palynomorphological characteristics of the order Asterales are discussed. Particular attention is paid to the pollen morphology of basal families of this group and to that of problematic taxa that are considered as sister ...
-
(2006)Strongly contrasting rocks were juxtaposed during the long tectonometamorphic history of the Mozambique Orogenic Belt in northern Mozambique. The latest depositional event was expressed by accumulation of marine sediments, ...
-
(2006)Several long-range seismic profiles were carried out in Russia with Peaceful Nuclear Explosions (PNE). The data from 25 PNEs recorded along these profiles were used to compile a 3-D upper mantle velocity model for the ...
-
(2006)The family Heliodiscidae Haeckel, 1881, which includes five genera, is reviewed. New methods of investigation are applied to the inner structure of Cretaceous spherical radiolarian skeletons, which reveal numerous taxa ...
