Perifrontal Forms of the Late Cretaceous Modular Hexactinellids (Porifera)

Certain tendencies are supposed to show up in morphogenesis of the Late Cretaceous skeletal sponges, hexactinellids; those tendencies make it possible to distinguish some forms of diverse-level modular organization among the unitary representatives of the group. Generation of primitive ≪modular≫ forms, defined as the perifrontal ones, is associated with incomplete gemmation and isolation of solitary cross canals, apo- or prosochetes

New Records of the Chimaeroid Genus Stoilodon Nessov & Averianov, 1996 (Holocephali, Chimaeroidei) Remains from the Late Jurassic and Early Cretaceous of European Russia

Based on new finds of mandibular tooth plates of the chimaeroid Stoilodon aenigma Nessov &Averianov, 1996 (Holocephali, Chimaeroidei) from the Lower Cretaceous of central Russia, the diagnosis of the genus is modified and validity of the taxon is confirmed. New record of mandibular plate of the species from the Ryazanian regional stage (boreal Berriasian stage) of the Moscow Region has allowed us to expand stratigraphical distribution of the species within the whole early Cretaceous. It is estimated that Stoilodon did not exceed 1.5 m in body length.

Results of ekologo-geochemical approbation in territory of preschool institutions of a city of Engels are presented. The data about disease of children in the given establishments on various types of diseases is analysed. The estimation of an ecological condition of a soil cover is given

The Precaspian Depression Geothermal Conditions and Heat and Fluid Flows

The Precaspian depression subsoil geothermal mode characteristics result not only from presence of the huge evaporite formations and salt dome tectonics, but also from the depth structure of its no granite crust and underlying lithospheric mantle. The current heat flow is primarily of mantle origin and correlates with the HC, helium and other mobile components deep fluid flow.

Internal Salt Tectonics within the Halogenic Series in the Gremyachinskoye Potassium Salt Field

Explorations of 1979–1982 and 2006–2009 have made the field ready for industrial development and have revealed peculiar manifestations of internal salt tectonics within the subhorizontal halogenic bodies. The degree and the character of intrasalt tectonics are estimated according to boudinage, i. e. the response of the rigid dolomite- anhydrite interlayers within the salts to arising tectonic stresses. Upon folding, the interlayers are torn into separate fragments and stretched along the bedding.

Synsedimentation Hydrothermal Processes as Event Indicators for Interregional Correlations of Triassic Sequences

Event stratification of the sections constitutes an investigation trend aimed at detailed interregional correlation of sedimentary sequences. Based on extensive factual material, the authors have revealed the most significant changes in the Middle Triassic sedimentary and volcanogenic-sedimentary bodies. The entire Middle Triassic is peculiar for manifestations of hydrothermal-metasomatic processes within terrigenous, biogenic, volcanogenic bodies and bodies of mixed origins.
