-
(1989)The main objective of modern techniques of oil and gas prospecting is to increase the efficiency and especially the reliability of predicting the oil and gas prospects of local uplifts or uplift zones. The current procedure ...
-
(2002)New strategies are presented for the analysis of the high-precision geomagnetic data that are currently obtained by the low-orbiting satellites Orsted, CHAMP and Orsted-2/SAC-C. The measured magnetic field is the sum of ...
-
(2003)New finds of crocodiles and dinosaurs from the Late Jurassic deposits of southwestern Mongolia (Shar-Teg locality) and Eastern Siberia (basin of the Vilyui River, Teete locality) are described. A new species of small-sized ...
-
(2003)A molecular study of linear, branched and isoprenyl alkylbenzene skeletons and alkenylbenzenes in the soluble fraction extracted from a sulfur-rich Utrillas coal was carried out using gas chromatography-mass spectrometry ...
-
(2003)Laboratory tests have been carried out to determine the physical properties of high sphericity and low density, fine grained dry granular materials. In particular, we tested hollow aluminium microspheres and hollow siliceous ...
-
(2003)Analysis of tectonic stress from the inversion of fault kinematic and earthquake focal mechanism data is routinely done using a wide variety of direct inversion, iterative and grid search methods. This paper discusses ...
-
(1985)Episodic volcanism favors, as shown by examples from Europe, the USA, and Brazil, the formation of organic-rich sediments (hydrocarbon source rocks). The examples examined from Europe comprise the Lower Carboniferous ...
-
(2001)Two new athyridid genera, Fastigata with the type species F. longa sp. nov. and Mica with the type species M. borea sp. nov., are described from the Lower Devonian deposits of Eastern Yakutia.
-
NEW BIOSTRATIGRAPHIC AND PALEOMAGNETIC DATA ON THE DEVONIAN IN THE WESTERN MONGOL-OKHOTSK FOLD BELT (2001)Crinoids of the Lower-Middle Lochkovian were first determined for the Devonian deposits of the Mongol-Okhotsk fold area, and also first preliminary paleomagnetic data were obtained for these deposits. Lithological and ...
-
(2003)Four new taxa of the subfamily Brachyericinae, Exallerix manahan sp. nov. (Lower Oligocene of Mongolia), Synexallerix otus gen. et sp. nov. (Lower Miocene of eastern Kazakhstan), Postexallerix securis gen. et sp. nov. ...
-
(2001)Five new species of trepostomid bryozoans are described from the Middle and tbe Upper Devonian of Transcaucasia: Schulgina ulilinae, Leptotrypa simplex, Leptotrypa dansikensis, Ataclotoeclms interruptus and Anomalotoeclms ...
-
(1997)This paper presents a new calibration for infrared analyses of dissolved water and its species concentrations in rhyolitic glasses. The new calibration combines infrared/manometry measurements and infrared study of hydrous ...
-
(2004)Chonetids of a new genus and species, Kaninochonetes kaninensis gen. et sp. nov., are described from the Upper Permian Ufimian Stage of the Kanin Peninsula.
-
(1997)Alluvium of the Zolotaya river in the Western Sayan mountains contains an Os-Ir-Ru association of PGE minerals related to hyperbasites of the Kurtushibin ophiolite belt. Besides the typical minerals of the harzburgite ...
-
(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 ...
-
(2000)A new, 14C-verified borehole stratigraphy provides the first age-controlled reconstruction of the late Quaternary glacial history of the Pechora Sea (southeasternmost Barents Sea). A complete glaciation of the Pechora Sea ...
-
(2004)The behavior of dissolved Hf in the marine environment is not well understood due to the lack of direct seawater measurements of Hf isotopes and the limited number of Hf isotope time-series obtained from ferromanganese ...
-
(2003)Carbon and oxygen isotope data from a succession of Cretaceous (Barremian-Cenomanian) age recovered from the Pacific Ocean (DSDP site 463) are presented. The carbon isotope curve reveals a large isotope excursion within ...
-
(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 ...
-
(2001)Traditional Crucibles for noble gas extraction made of refractory metals are not suitable for metallic samples because these are easily alloyed with liquid metals. To obtain elemental and isotopic compositions of noble ...
