(2002)Dismembered ophiolites occur in the Dinaride Ophiolite Zone (DOZ) that is related to the open-ocean Tethyan realm, whereas highly dismembered ophiolites occur in the Vardar Zone (VZ) related to a back-arc basin. The ...
-
(2001)It is proposed that there are three types of gold deposits in Eastern and Central Transbaikalia (Trans-Baikal province), namely: (i) high-sulphide intrusion-related deposits with some signs of porphyry deposits, (ii) ...
-
(1989)Analysis of the evolution of Phanerozoic stratigraphic complexes of the western margin of the East European craton (EEC) and the Central European Platform (CEP) shows that their formation depended on the corresponding ...
-
(1999)A new genus Gobicar with a single species, G. ponomarenkoi from the Shar-Teg locality is described. A combination of its characters indicates that it is the most primitive member of the Eccoptarthridae.
-
(1999)The Rb-87/Sr-86 and Sr-87/Sr-86 ratios of Laptev Sea sediments, of Arctic Ocean sediments and of suspended particulate matter (SPM) from Siberian rivers (Lena and Khatanga) form 'pseudo-isochrons' due to grain-size separation ...
-
(2020)A bed-by-bed biostratigraphical study of two key Californian outcrop sections of the JurassiceCretaceous transition interval is presented. The studied succession is characterized by the occurrence of abundant buchiid ...
-
(2002)Three horizons of phthanites and black carbonaceous mudstones are distinguished in the key section of Triassic and Jurassic cherty deposits of the Gorbusha Sequence near the Settlement of Dal'negorsk (Sikhote Alin). The ...
-
(2001)Horst-accretionary systems (HAS) extended to the northeast and alternating with rift-grabens (RG) were established within the bounds of the southeastern margin of Asia. The synchronous formation of these positive and ...
-
(2003)A detailed record of sea surface temperatures in the Northern Hemisphere based on migration of marine invertebrate fauna (ammonites) and isotopic thermometry (δ18O values of shark tooth enamel) indicates a severe cooling ...
-
(1991)A Bathonian volcanogenic unit in northern Karabakh was examined. It was established that it belongs to a tholeiitic series of the ferruginous moderately highly titaniferous type. Two complexes were identified: an early ...
-
(1988)We analyzed asphaltenes of crude oils and bitumens in dispersed organic matter from various regions of the West Siberian block and the Siberian craton. The West Siberian crude oil samples were collected from Jurassic and ...
-
(2001)Isotopic dating showed that rhyolites of the Kushmurun graben are divisible into two groups different in age. One group is close to the Induan-Olenekian boundary in its chronostratigraphic position and has K-Ar and Rb-Sr ...
-
(1987)The Dauletabad-Donmez gas field is in the southern part of the Amu Dar'ya oil and gas province. The identification of the origin and sources of H2S in gases of the Dauletabad-Donmez field is very important, particularly ...
-
(2004)This contribution presents the first detailed oxygen and carbon isotope record from the latest Jurassic-early Cretaceous interval of the Yatria River, subpolar Urals, Siberia. Isotopic compositions have been determined on ...
-
(2002)Structural features and composition of Jurassic deposits in the Kafan tectonic block that is located in the southeastern part of the Lesser Caucasus are considered. Three carbonate members bearing foraminifers are distinguished ...
-
(2004)The study is devoted to Jurassic gastropods of the Central and Central Chernozem regions of Russia. Thanks to the exact locality data on the collected material, the stratigraphic ranges of many species were refined. Several ...
-
(2004)A caddisfly Dolophilodes ( Sortosella ) shurabica subgen. et sp. nov. (Philopotamidae) is described from the Jurassic of Kyrgyzstan, from the Sai-Sagul locality. The ecology and taphonomy of this locality are analyzed, and ...
-
(1999)The latitudinal models of radiolarian paleogeographic provinces are considered, and Late Jurassic boreal radiolarian assemblages of Russia are characterized. Several Jurassic radiolarian assemblages from the Koryak Upland ...
-
JURASSIC TRACHYBASALT-COMENDITE-ALKALI GRANITE VOLCANO-PLUTONIC ASSOCIATION OF EASTERN TRANSBAIKALIA (1989)Alkali basalt-comendite associations are a typical rock type of rift-generated structures and are known both in continental regions (the Basin and Ridge Province of the U.S., and in Mongolia) and in island-arc regions ...
-
(2002)Geologic and paleomagnetic research in the western part of the Omolon massif and in the Sugoi folded zone, northeastern Russia, suggests significant lateral displacements of these units relative to one another and with ...
