(1996)Five overlapping sections from the thick Neoproterozoic to early Cambrian sediments of western Mongolia were analysed to yield a remarkable carbon-isotope, strontium-isotope and small shellyfossil (SSF) record. Chemostratigraphy ...
-
(1996)Carbonate-rich sedimentary rocks of the western Anabar region, northern Siberia, preserve an exceptional record of evolutionary and biogeochemical events near the Proterozoic/Cambrian boundary. Sedimentologically, the ...
-
(1996)A high-resolution Sr isotope study of Middle to Upper Cambrian platform carbonates of the southern Great Basin significantly refines the structure of the existing seawater Sr isotope curve. Samples were selected using ...
-
(2013)The interplay of geodynamic and sedimentation processes in the Central Asian orogen and the Siberian craton is discussed in several aspects: (i) general tectonics of the Central Asian orogen, (ii) correlation of deposition ...
-
(2001)Sensitive high resolution ion micro-probe (SHRIMP) U–Pb analyses of zoned zircons were performed to constrain the age and geodynamic significance of the Kokchetav ultrahigh-pressure (UHP) metamorphic rocks, which recrystallized ...
-
(1999)Carbon and oxygen isotope variation curves for Vendian-Lower Cambrian carbonates of the Bokson Group are correlative with those characterizing coeval sections in Siberia and western Mongolia. The curves demonstrate the ...
-
(1999)Abstract-Two clay fractions of a Cambrian claystone from Estonia, consisting essentially of illite and 20% expandable illite-smectite, (I-S) were treated with C12 and C,8 alkylammonium cations for K-exchange. Both the ...

-
(1989)Most oil and gas pools found in the Lena-Tunguska oil and gas province of the Siberian craton are known to be confined to granular or fractured-granular reservoir rocks in clastic sandstone-siltstone strata. Such rocks ...
-
(2003)The Vendian-Early Cambrian, Middle Cambrian, and Early Ordovician volcanosedimentary deposits of the Martaiga Block of the Kuznetsk Alatau paleoisland arc (55.5° N, 88° E) have been investigated paleomagnetically. Their ...
-
(2004)Upper Cambrian-Lower Ordovician volcanic-siliceous-terrigenous strata of the Zasur'ya Group belonging to the Gorny Altai segment of the Paleo-Asian Ocean are considered in this paper. The Gorny Altai segment developed over ...
-
(1999)Early Cambrian sediments on the East European platform in North Estonia, represented mostly by clays and silty clays, were deposited under normal marine conditions. The sediments were never affected by significant tectonic ...
-
(2003)Marly limestones that crop out along the Khorbusuonka river (northeastern Siberian platform) define a well-dated Lower and Middle Cambrian sequence which was sampled for magnetostratigraphy. In the upper part of the section, ...
-
(1984)Four sedimentary sections seen in continuous exposures along the Lena River on the Siberian Platform in Yakutia contain a record of the geomagnetic field during the Tommotian and Atdabanian stages of Early Cambrian time. ...
-
(2002)We have characterized complexes of the guide faunal groups (small-shelled fauna, archaeocyathids, trilobites, and brachiopods) and followed their stratigraphic and lateral distribution in the Cambrian deposits of the ...
-
(2004)A monographic description of mollusks from the Lower Cambrian Bystraya Formation of Eastern Transbaikalia is presented for the first time. The mollusk assemblage includes ten species of nine genera; the following six species ...
-
(2002)The alignment of olivine crystals is considered as the dominant source of seismic anisotropy in the subcrustal lithosphere and asthenosphere. Different components of large-scale anisotropy can be traced in depth distributions ...
-
(2002)In the Vendian-Cambrian orogenic belt of the Chagan-Uzun and Kurai areas, Gorny Altai, high-pressure, low-temperature (HP/LT) metabasites and associated schists comprise a metamorphic complex less than 2 km thick. The ...
-
(2003)Fossil bacterial remains from black carbonate shales of the Sinsk Formation from the Lower Cambrian of the Siberian Platform are studied. The main types of fossil microbial remains found in these strata are described.
