THE PALAEOZOIC IN THE SŁAWATYCZE ANTECLISE IN VIEW OF RECENT DRILLINGS

The author's paper represents an interpretation of the structure of the Sławatycze anteclise and its "periphery", based on exact data obtained from drillings and geophysical examinations. The paucity of geological data and the ensuing diversity of interpretations of the geophysical results is illustrated by the morphological maps hitherto prepared of the crystalline substratum forming the Sławatycze anteclise and its adjoining units.

The depth of the top surface of the crystalline substratum as well as of the successive stratigraphical horizons varies. In the geological sections presented (Mielnik-Wisznice-Kapłonosy, Radzyn-Wisznice, and Nowosiełki-Bereżce), showing the relief of the substratum and the geological structure of the superimposed rock formations reflect these depth data.

The Eocambrian and Cambrian rocks occurring In the eastern part of Poland show the characteristic features of Platform adjoining sediments. The common features of these sediments enables us to distinguish certain series of sediments for which, during preliminary investigation, it proved necessary to employ local names. Thus, the series distinguished were called as follows: The Sławatycze series (tuffo-volcanic rocks), the Siemiatycze series (coarsegrained sandstones), the Lublin series (sand and siltstone deposits with glauconite), the Masovian·series (sand and siltstone deposits with less glauconite), the Kapłonosy series (unequigranular friable sandstones), the Radzyń series (argillaceous sand and silts tone deposits), and the Kostrzyń series (compact and friable sandstones).

These series have been correlated with Eocambrian and Cambrian rock series determined in White Russia.
