ABSTRACT: Paleographic Atlas of Northern Eurasia: Aims and Current Progress

A project aimed at paleographic reconstruction of northern Eurasia (the former USSR and adjacent territories) commenced in 1993 in Russia under the auspices of two nongovernmental scientific organizations: Scientific Council on Plate Tectonics and Institute of Tectonics of Lithospheric Plates. The project is sponsored by the State Committee on Geology and Exxon and Shell companies.

Twenty-six data-base maps and corresponding paleogeographic maps on a set of new paleotectonic reconstructions are to be compiled within two years, covering a period from Devonian to present. The next two-year phase is expected to follow, with a compilation of similar maps for Early Paleozoic and late Riphean. The best experts on regional geology, paleoenvironment, paleomagnetics, and paleotectonic reconstructions participate in the program. A special group, Geocentre Company, is assigned to the computerization of maps. The 1993 compilation of 15 database maps is to be completed and the first reconstructions produced. The database maps (starting from Tithonian upward) contain information on lithology, facies and thickness of sedimentary formations, and magnetic and structural indicato s of plate tectonic data; oil and gas deposits are indicated. Emphasis is placed on the paleogeographic evolution of sedimentary basins, potential reservoirs of hydrocarbons. Narrow time intervals between maps (about 10 m.y.) permit detailed reconstructions of the basins' evolution. Examples of database and paleogeographic maps are presented in the poster.
