-
(PANGAEA, 2009-10-16)The redox stratification of bottom sediments in Kandalaksha Bay, White Sea, is characterized by elevated concentrations of Mn (3-5%) and Fe (7.5%) in the uppermost layer, which is two orders of magnitude and one and a half ...

-
(1996)Hydrothermal water enters Frolikha Bay, a well-known site of high geothermal heat flux in the northern part of Lake Baikal, at 400 m depth. On the basis of CTD profiles, the hydrothermal water is identified as forming an ...
-
(2004)Lithologic-facies and ecologic-taphonomic methods are jointly used to study the Lower-Upper Permian boundary deposits of a complex structure, which are represented by laterally variable marine, coastal, deltaic, lagoonal, ...
-
(2005)This paper presents the results of the paleomagnetic and magnetic mineralogical studies carried out along the sequence of the recently discovered oldest Nedubrovo (Early Triassic) rocks of the Moscow Syneclise, exposed in ...
-
(2004)Robust magnetotelluric response function estimators are now in standard use in electromagnetic induction research. Properly devised and applied, these have the ability to reduce the influence of unusual data (outliers) in ...
-
(1995)Constraints on steady state flow strengths of multiphase aggregates can be obtained by the bounds calculated using the assumption of uniform stress and uniform strain rate within the aggregate. This study shows that such ...
-
(2006)A multi proxy approach was performed to characterize vegetation in southwestern Bulgaria during the end of the Early and the Middle Turolian (8.7–7.0 Ma). This period was marked by eustatic fluctuations in the Mediterranean ...
-
(2006)It has long been recognized that the trend of marine diversity from the Carboniferous to the Triassic includes an approximately 100-myr-long stable biodiversity stage ranging from the Late Carboniferous to the late Middle ...
-
(2006)Four new ambocoeliid species, Ambocoelia ectypa sp. nov., Echinocoelia tikhiensis sp. nov., Emanuella takwanensis (Kayser), and Ladjia sita sp. nov., from the Givetian of the southern Verkhoyansk Region are described ...
-
(2001)Abstract-Licharewia-Yike brachiopods from northeastern Russia are studied. Their generic diagnoses are emended and their species composition and stratigraphie range are revised. Two new genera Neotumarinia and Labuella are ...
-
(2000)The phylogeny and taxonomy of a new tribe of the Productidae, the Reticulatiini Lazarev, trib. nov., is examined using meronomic analysis. New morphological features of these productids are described. Problems of productid ...
-
BRACHIOPODS OF THE REDEFINED FAMILY TRITOECHIIDAE FROM THE ORDOVICIAN OF KAZAKHSTAN AND SOUTH URALS (2001)The Tritoechiidae are redefined following study of nine species of the genera Tritoechia, Eremotoechia, Martellia Pomatotrema, Protambonites and Korinevskia nov. gen. in Kazakhstanian brachiopod faunas from the upper ...
-
(2003)In addition to the initial spine-distribution pattern, in which the posterior and anterior spines on the ventral valve surface are of approximately the same thickness, the Linoproductoidea evolved (very early in the ...
-
(2002)Brachiopod-dominated palaeocommunities incorporating a structure typical of faunal groups within the Palaeozoic Evolutionary Fauna were already present in North and East Gondwana and associated terranes as early as the ...
-
(2001)Bradaczekite, NaCu4(ASO(4))(3), was discovered in a fumarole in the North Breach of the Great fissure Tolbachik eruption (GFTE) in 1975-1976, Kamchatka Peninsula, Russia. Bradaczekite forms allregates of dark blue plates ...
