Tectonic map of the basement of the Mid-Ob' plate complex (West Siberia)

On the basis of analysis of the available data of drilling, geophysical sur vey, and previous geological and structural models, a tectonic map was comp iled for the basement of the central, Mid-Ob', part of the West Siberian Pl ate. This map shows outlines of large tectonic features where they come to the surface of the basement, indicates the formational composition, shape, and stratigraphic volume of the objects mapped, and tentatively displays th e vertical sequence of their occurrence. Substance composition and geometry are used to compile the legend and to qualitatively differentiate the mode rn structure of the objects under study irrespective of the existing global concepts as well as to compile sets of tectonic maps made at different sca les but using a common procedure of separation of the mapped tectonic units of different ranks.
