(2004)It can be assumed that orebearing volcanosedimentary sequences of Rudnyi Altai began to form since the Emsian at the transition from the axial rift of the Ob-Zaisan ocean spreading to the continental rift of the Altai-Mongol ...
-
(1990)A new copper-ore show was found within the Devonian clastic series in the southeast of Haakon VII Land, on Mt. Sigurd, near the tectonic contact with the Upper Proterozoic metamorphic rocks of the Hekla Hook complex. The ...
-
(1996)The paper present descriptions of the sections of the Saumalkol' Formation situated in the Northern part of the Karasor synclinorium in Central Kazakhstan. Particular attention was devoted to finds of fauna and flora and ...
-
(1990)There is little information about pre-Late Paleozoic volcanism in Siberia because the corresponding volcanic systems were largely eroded during the Mesozoic. However, by studying the few volcanic bodies now known and ...
-
(2001)New materials on the psammosteid heterostracan Pycnosteus palaeformis Preobr. characteristic of the Aruküla deposits (Middle Devonian, Eifelian) of the Main Devonian Field are presented. A pentagonal rounded, slightly ...
-
(2003)Two new genera, Fistuliphragmoides, with its type species F. gobiensis sp. nov., from the Emsian of southern Mongolia and Boardmanella, with its type species B. richardi sp. nov., from the Givetian of eastern Mongolia are ...
-
(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 ...
-
(2003)New genera based on new type species, Paramichelinoceras (P. agatovense), Oisengoceras (O. burskyi), Mimokionoceras (M. valentinae), Neritoceras (N. rakovense), Dawsonoceroides (D. nekhvatovensis), Eomooreoceras (E. ...

(1998)Newly determined U–Pb zircon ages of volcanic ashes closely tied to biostratigraphic zones are used to revise the Devonian time-scale. They are: (1) 417.6±1.0 Ma for an ash within the conodont zone of Icrioduswoschmidti/I. ...
-
(2001)A new genus Liratella and its type species L. miranda from the Famennian of the southern Urals are described. The literature sources on Trachypsammiida are summarized.
-
(2004)The Dniepr–Donets Basin (DDB) is a Late Devonian rift structure located within the East-European Craton. Numerical heat flow models for 13 wells calibrated with new maturity data were used to evaluate temporal and lateral ...
-
(1988)This study looks at the nature and tectonic position of the Protogaean deposits in the Tien Shan system. It confirms the view that old endogene ore mineralization in the polycyclic Tien Shan is relatively poorly developed, ...

(1990)An ore show of phosphate raw material has been found for the first time on the east slope of the Urals, in the basin of the Man'ya River in the Circumpolar Urals. The residual-infiltrational or chemogenic-mechanogenic ...
-
(2004)The type species of the genus Conispirifer Ljaschenko, C. rotundus Ljaschenko, is revised based on the material from the Upper Devonian of the southern Timan. C. rotundus was established based on juveniles of Tenticospirifer ...
