(2003)Alkaline ultramafic rocks associated with carbonatites in the southern margin of the Siberian Platform are restricted to the marginal suture (Main Sayan fault) [5, 6]. They are not promising for diamond potential. Despite ...
-
(2002)Environmental variables such as temperature and salinity cannot be directly measured for the past. Such variables do, however, influence the chemistry and biology of the marine sedimentary record in a measurable way. ...
-
(2001)Seven new species of Ostracodes are described in six genera. Representatives of the genus Parapokornyella are recorded for the first time in southwestern Crimea, from the Cretaceous/Paleogene boundary beds.
-
(2001)Two new species of the genus Liostrea-L. volgensis and L. samtoviensis-are described from the Santonian deposits of the Saratov and Volgograd Regions.
-
(2004)Two new palaeoryctids from the Eocene Asiatic genus Nuryctes are described. N. alayensis sp. nov. (terminal Lower Eocene, Alai Beds, Andarak 2 locality, Kyrgyzstan) is more primitive in the extent of premolar reduction ...
-
(2002)In order to better understand the tectonic evolution of central Asia under the influence of the India-Asia collision, we carried out a paleomagnetic study of 1500 cores from 106 sites along the Altyn Tagh fault, in the ...
-
(2003)The aim of this project was to study the paleomagnetic stratigraphy of the Hauterivian-Aptian deposits in the Middle Volga region, namely in the areas of the Saratov, Samara, and Uliyanovsk right-hand Volga areas. Original ...
-
(1999)New paleomagnetic data on the Early Cambrian of the north of West Sayan are presented. The magnetic properties of rocks of the Lower Monok and Upper Monok Formations are investigated. Mineral compositions of major carriers ...
-
(2003)Paleomagnetic measurements were made on samples from Silurian, Devonian, Carboniferous and Permian aged rocks from the Omulevka terrane, northeast Russia. The Omulevka terrane is a fragment of continental margin that forms ...
-
(2002)Two new species and one new subspecies of the family Arcidae, i.e., Arca parita, A. nefanda, and A. conformis mandrikovkaensis, from the Paleogene deposits of Ukraine, are described. Several new species of the families ...
-
(2002)Two new species of the Terebratulida belonging to the superfamily Centronelloidea Waagen, 1882, and two new species and one new genus belonging to the superfamily Dielasmatoidea Schuchert, 1913, are described from the ...
-
(2003)Five new species and one new genus belonging to the superfamily Terebratuloidea Gray, 1840 (order Terebratulida, Brachiopoda) are described from the Permian of the southwestern Darvaz (Tajikistan).
-
(2003)Three new species and one new genus of Terebratulida belonging to the superfamily Loboidothyroidea are described from the Permian of the southwestern Darvaz (Tajikistan). The terebratulid assemblage from the Permian of ...
-
(2004)New chonetid genera and species, Binderochonetes manankovi (subfamily Striochonetinae of the family Rugosochonetidae) from the Tatarian Stage of the Upper Permian of northeastern Mongolia and Adatsagochonetes mongolicus ...
-
(2000)This survey of the current status of research into Earth’s orbitally forced paleoclimatic record summarizes recent developments in the theory of Earth’s orbital parameters, and reviews how various techniques of data ...
-
(2003)A new monotypic genus, Archaranthus gen. nov. (Platanaceae) with A. krassilovii sp. nov. as its type species, is erected for staminate inflorescences from the Maastrichtian-Paleocene deposits of the Amur Region on the basis ...
-
(1987)The present paper describes a method of local laser-aided determination of the degree of disruption of the K-Ar system of the specimen. To combine the advantages of the age spectrum method with the localized character of ...
-
(1989)The discovery of the Nepa potash salt basin [1] raised the question of whether analogous basins exist elsewhere in the Irkutsk amphitheater. Therefore, it is especially important to study the formation and subsequent ...
-
(1989)Gabbro-monzodiorite plutons in different parts of Mongolia are lumped together with the granitoid bodies intruding them into the gabbro-monzonite-granosyenite, monzonite-granosyenite-granite and other rock associations, ...
-
(1990)At present the chief method of investigating the structure of the crust is deep seismic sounding (DSS). When interpreting DSS data, the main focus is on kinematic characteristics of refracted waves, and practically no ...
