A geological map shows an outcrop pattern of rock units (usually lithostratigraphic) which after having experienced more or less severe tectonic deformation have become structural parts of the solid earth crust. Thus, such a map along with a complementary cross section(s) depicts tectonic structure of a given region at appropriate scale. While speaking about geology of the region one has to identify tectonic units and their boundaries (i.e. deformational structures) on the map and distinguish them by applying proper tectonic terms. In any region, such terms should be accompanied by geographical names to allow for the distinction between particular, more local tectonic units. Once given name should not be changed or replaced by others without producing justified reasons for that. This is an essence of tectonic regionalization which is often misused in recent practice conducted in Poland. In consequence, some units are addressed by 3 or 4 different terms, not seldom with different genetic connotations, or refer to units without determined boundaries. Such an unwelcome practice should be abandoned as it produces serious confusions and misunderstandings among geologists and still more, which is even worse, among non-geologists. The geological structure of Poland requires presentation on two maps. One of them is to show the picture available after removing Cenozoic cover and the other showing the picture after removing Permo-Mesozoic strata. A brief glossary of tectonic terms recommended by the Committee for Geological Sciences PAS is attached.

Geologically, southwestern Poland is located between the Upper Elbe Fault Zone on the SW and the Dolsk Fault Zone on the NE. It comprises two major crustal blocks: the Lower Silesian Block and the South Wielkopolska Block separated by the narrow Middle Odra Horst. The Lower Silesian Block is principally subdivided into the Fore-Sudetic Block and the Sudetic Block. These blocks are further subdivided into several smaller tectonic units. Their boundaries and main features are briefly characterized. It is proposed here to initiate a discussion on internally coherent tectonic subdivision of the region, principles of such subdivision and due revision of the hitherto used terminology. The discerned tectonic units generally do not coincide with physiogeographic subdivision, thus it is not recommended to confuse the geographic and geologic regionalization.

The attempt to divide the Upper Silesian Block and the Małopolska Block into tectonic units has been based on a general map at scale of 1:1000000, without Permian-Mesozoic and Cenozoic strata. Cartographic, general and monographic works regarding formation of Precambrian basement of both of the blocks have been discussed and presented, and data concerning development of sedimentation, tectonics, and structure of the Paleozoic cover of the blocks were the background for the suggested division. The Upper Silesian Block is a part of a larger unit determined as the Brunovistulicum, which together with the Brno Block are entirely located within the borders of the Czech Republic. The Brunovistulicum and the Małopolska Block vary in formation of Precambrian basement and covering Paleozoic formations, what proves different paleogeographical-facial and paleotectonic development. Current data do not allow determining their southern range, where both units are within the range of the orogeny of the Outer Carpathians and quite possibly in the range of the Inner Carpathians. The boundary of the Brunovistulicum and the Małopolska Block along the part between Lubliniec and Cracow and farther to the vicinity of Bochnia and Nowy Sącz is relatively well defined and documented. It is a narrow Cracow-Lubliniec fault zone, approximately 500 m wide, cutting and moving all rock series of the Precambrian and the Paleozoic. The fault zone of the Odra River probably forms its NW continuation. The following tectonic units have been distinguished in the Upper Silesian Block: 1) Moravian-Silesian Fold-and-Thrust Belt, 2) Upper Silesian Fold Zone, 3) Upper Silesian Trough, 4) Bielsko-Biała Dome, 5) Rzeszotary Horst, 6) Liplas Graben. There is only one tectonic unit distinguished in the Małopolska Block-Kielce Fold Belt, dipping towards NW-SE, along the NE boundary of the block. Paleozoic formations building the unit represent thrust fault structure. In this case, the Kielce Fold Belt significantly varies from the other parts of the Małopolska Block, where Paleozoic formations build numerous small block structures.

Presented paper is a contribution to discussion about the tectonic regionalization in Poland. The Polish Lowlands, located between the Baltic shore and the highlands of the southern and central Poland, is the area discussed here. In this region mainly the Quaternary and the Neogene deposits with thickness rarely over 300 m are exposed. On the sub-Cenozoic surface occur mainly Cretaceous, Jurassic and Triassic rocks. Structural forms of the Polish Lowlands are directly associated with the Permian-Mesozoic Polish Basin inverted at the beginning of Cenozoic time. It is worthwhile indicating here that not only the Polish Trough was inverted but also the distal part of this basin, distinguished now as the Fore-Sudetic Monocline. Subdivision of the Polish Lowlands into tectonic units on the sub-Cenozoic surface was shown on Fig. 1. In the mid-Polish area antyclinorium belts of north-west to south-east orientation are located. The basement of the Polish Basin is built of the pre-Permian deposits, tectonized during pre-Alpine phases. To analyze the geology of Poland in the sub-Permian architecture the proper tectonic map (Fig. 2) is required with only the units of first order marked. Debate on tectonics of Poland requires also a map of basement consolidation units (Fig. 3). Indispensable completion of the presented maps is a geological cross-section of the Polish Lowlands (Fig. 4). It is clear that tectonic regionalization of Poland (with special attention to the Polish Lowlands) should be demonstrated on the three basic maps here presented. Spatial (both horizontal and vertical) relations between tectonic units should be considered in the light of sedimentary basin analysis, i.e., searching processes and stages of the structural evolution which essentially contributed to the recent tectonic diversification in regional geology.

Discussion on the tectonic regional subdivision of Poland is a good opportunity to show a range of geological information of each tectonic unit and to emphasize the necessity of improvement of geological tectonic classifications, application of which in the geological databases is essential for correct usage of data collected. A good example is a geological and geophysical database PITAKA developed in the Polish Oil and Gas Company from 1987. Actually the PITAKA database contains data from 3191 boreholes which drilled Permian and younger deposits and from 4555 boreholes pierced into the older rocks. This paper presents location of 2D and 3D seismic studies done in digital technology from its introduction in Poland in 1973. In the Polish Lowlands area the Fore-Sudetic Monocline is the best geologically recognized region. The Pomeranian Anticlinorium and the Szczecin-Gorzów Synclinorium are relatively well documented. Numerous boreholes and seismic sections in those areas are associated with intensity of exploration of raw material deposits such as hydrocarbons, coal, copper, zinc and lead, sulfur and salts. Until now the PITAKA database does not contain all drilling data from Poland but it is constantly extended and supplemented.
