-
(1987)The basalts investigated were penetrated in drillholes near the villages of Nizhniy Mamon and Podkolodnovka as three flows with an overall thickness of 3 to 57 m. An earlier study of mineral and chemical compositions of ...
-
(1989)Our work gave new paleontologic and radiometric data on the age of the sedimentary, volcanogenic-sedimentary and igneous rocks in the structurally most complex northern part of Bering Island, which supplement existing ...
-
(1988)The high-pressure rock association in one area of Sakhalin is described. Within the area studied, the high-pressure association forms a sublatitudinally oriented zone, 300 to 500 m wide and composed mainly of alternating ...
-
(1998)The first finding of coesite in the garnet-mica schist of the Kulet site of the Kokchetav Massif is described. This fact indicates that the upper eclogite-bearing unit of the Kokchetav Massif was metamorphosed at pressures ...
-
(2003)The course of the nasolacrimal duct, interdental plate morphology, and most details of tooth and denticle morphology have not previously been described in non-archosauriform reptilkes. Here I describe these details in the ...
-
(1990)Deep seismic sounding with a total length of more than 8000 km was performed on 15 traverses through the Urals between 1962 and 1988. In addition, areal investigations have been performed in the middle and southern Urals. ...
-
(2002)New insect taxa from the Ufimian of Cherdyn' District, Perm Region, Visherifera camura gen. et sp. nov. (Grylloblattida: Visheriferidae fam. nov.), Misthodotes visherensis sp. nov. (Ephemeroptera), and Idelopsocus incommendatus ...
-
(2004)Orthorhombic edingtonite has been found coexisting with tetragonal edingtonite in a specimen from Ice River, British Columbia, Canada. We report data on the composition and crystal structure of the orthorhombic sample. ...
-
(2005)Ruthenium tetroxide oxidation was used to examine the macromolecular insoluble organic matter (IOM) from the Orgueil and Murchison meteorites and especially to characterize the aliphatic linkages. Already applied to various ...
-
(2002)The Os isotopic compositions of mantle rocks generally are considered to be established during melt-depletion events and to be robust to subsequent disturbances (e.g. metasomatism). Consequently, Os isotopes are used to ...
-
(2002)We investigated the plausibility of remote fault triggering on a global scale as a result of postseismic stress transfer by large earthquakes. Previous studies have shown that the postseismic stress field generated by eight ...
-
(2003)Tiger's-eye is an attractive and popular gemstone that is ubiquitous in stores that cater to rock and mineral collectors. For more than a century, textbooks and museum displays have identified the material as an archetype ...
-
(1987)Recent work concerning the investigation of vertical movements in the Carpatho-Balkan Region is reported, based on the “Explanatory Text to the Map of Recent Vertical Movements in the Carpatho-Balkan Region”.For this ...
-
(2001)New isotopic-geochemical data were obtained in order to date the distinct evolutionary stages of the Chupa Formation in the Belomorian Mobile Belt. Reference U-Pb and Sm-Nd isotopic data are reported for relict rock volumes, ...
-
(2003)Two new species of scorpionflies of the family Orthophlebiidae, Orthophlebia gubini sp. nov. and O. shartegica sp. nov., are described from the Upper Jurassic of the locality of Shar-Teg, (Mongolia). A new scorpionfly, ...
-
(2001)New K-Ar age determinations on basalt samples from three drillholes and outcrops on Franz Josef Land suggest that flood volcanism throughout the archipelago fits in a very narrow age interval (116 +- 5 Ma). For 95% of the ...
-
(2001)The taxonomic composition of Late Hauterivian Terebratulidae of the Southwestern Crimea is reviewed. Two new genera, Middlemissithyris and Eichwaldithyris, are established, and six new species-Middlemissithyris rarus, ...
-
NEW LATE MESOZOIC MAYFLIES FROM THE SHAR-TEEG LOCALITY, MONGOLIA (INSECTA, EPHEMERIDA=EPHEMEROPTERA) (2002)New taxa of mayflies from the Upper Mesozoic Shar-Teeg locality in Mongolia are described. These are Furvoneta lucida sp. nov.; E sobria sp. nov. (Mesonetidae); Epeorominzus urnbratus sp. nov. (Epeo-romimidae); and ...
-
NEW LATE PERMIAN DICYNODONTS FROM THE VYAZNIKI ASSEMBLAGE OF TERRESTRIAL TETRAPODS OF EASTERN EUROPE (2001)Three dicynodonls belonging lo two new genera of the family Dicynodontidae, Delectosaunis arefjevi gen. et sp. nov. from the Voskresenskoe-2B locality (Nizhni Novgorod Region, Upper Permian), D. berezhanensis gen. et sp. ...
-
(2001)Remains of complex prokaryotic and eukaryotic organisms are found in the Seryi Klyuch Formation of the Yenisei Ridge. Taxa described here add substantially to our knowledge of Riphean paleobiology. Precambrian rocks are ...
