Pollen record of sediment profile NERO from Russia

(of book) Problems of origin of the hydrosphere, history of formation and development of underground water, of the World Ocean, lakes, rivers, surface and subsurface ice are under consideration in the book. An attempt of the complete reconstruction of the continental hydrosphere in the Eastern Europe in Late Pleistocene is made. Methods of paleohydrologic studies are described. Some papers are devoted to paleoclimatic problems of river runoff formation and paleotermic evolution of continental glaciers.

Calcareous nannofossil zonation, ages and sedimentation rates at DSDP Hole 76-534

A zonation is presented for the oceanic late Middle Jurassic to Late Jurassic of the Atlantic Ocean. The oldest zone, the Stephenolithion bigotii Zone (subdivided into a Stephanolithion hexum Subzone and a Cyclagelosphaera margerelii Subzone), is middle Callovian to early Oxfordian. The Vagalapilla stradneri Zone is middle Oxfordian to Kimmeridgian. The Conusphaera mexicana Zone, subdivided into a lower Hexapodorhabdus cuvillieri Subzone and a Polycostella beckmannii Subzone, is the latest Kimmeridgian to Tithonian. Direct correlation of this zonation with the boreal zonation established for Britain and northern France (Barnard and Hay, 1974; Medd, 1982; Hamilton, 1982) is difficult because of poor preservation resulting in low diversity for the cored section at Site 534 and a lack of Tithonian marker species in the boreal realm. Correlations based on dinoflagellates and on nannofossils with stratotype sections (or regions) give somewhat different results. Dinoflagellates give generally younger ages, especially for the Oxfordian to Kimmeridgian part of the recovered section, than do nannofossils.

Geological mapping of the Heber, Rhüdener Sattel, Northern Germany

This master thesis describes the geological mapping of an 8 km**2 area of the 300 m high elevation HEBER in Northern Germany which is part of the Rhüdener Sattel (Harzvorland). The geology consists of mesozoic rocks from Buntsandstein to Keuper; major parts are Muschelkalk, partly covered with a thin layer of Quaternary loess. The map includes measurements of strike and dip in various outcrops, drafting a scetch of the probable tectonic structure of Rühdener Sattel.

Palynological record of Lake Nero in Russia

This collection prepared to IX Congress of INQUA containes 25 articles concerning general and regional problems of Pleistocene. The chronological scale of the Late Pliocene and Pleistocene, climatical cycles and methods of the absolute dating are considered. Some data obtained by means ef paleomagnetic, thermoluminescence and radiocarbon methods at several point sections (Likhvin, Rostov-Jarosiavsky, Priasovje, Ob-garm, Chagan, Pryobskoje Plateau, Lower Volga) are given.
