The paper contains summary of the earlier studies of Lower Devonian palynostratigraphy and new results that relate to Middle and Upper Devonian and Frasnian. In the Giełczew PIG 5 borehole, the basal part of the Giełczew Member of the Telatyn Formation is included in the apiculatus-proteus (AP) Zone of the Emsian/Eifelian transition. The higher part of this unit is included in "Geminospora" extensa (Ex) Zone, Ex 3 Subzone, and the Geminospora aurita (Aur) Zone of mid and upper Givetian. The topmost part of the unit (Giełczew PIG 5 borehole) belongs either to the Aur Zone or to the succeeding zone Tholisporites densus (Den). This part of the section belongs either to the Givetian or to Frasnian. The presence of the Den zone in topmost part of the Giełczew Member (Giełczew PIG 6 borehole) has been ascertained. In the Terebiń IG 5 borehole, the Telatyn Formation, starting from the żniatyń Member, is included in The Ex 2, Ex 3 subzones and the Aur Zone. The uppermost part of the Rachanie Member belongs either to the Aur Zone or to Den Zone. The Frasnian index species Cristatisporites deliquescens has been recorded from the Krzewica Member of the Modryń Formation from the Terebiń IG 5 borehole. Stratigraphical information provided by the study of phytoplankton is not significant, but is consistent with the spore stratigraphy. Fluctuations of phytoplankton taxonomic diversity document some of the T-R cycles in the Lublin basin.

The paper presents the results of studies related to the desalination of low dissolved mineral content geothermal waters from the Banska IG 1 well using a dual hybrid system based on ultrafiltration and reverse osmosis. The desalination of geothermal waters may be considered a possible solution leading to the decentralisation of drinking water supply. In many cases, using cooled waters for drinking purposes may be considered an alternative method of disposing of them, in particular for open drain arrangements, i.e. where cooled water is dumped into surface waters. However, the utilisation or disposal of the concentrate in a fashion that is safe for the environment is an important part of the arrangement.

Łysogóry-Radom Basin (ŁRB) is bounded in the south by the deeply-rooted Holy Cross Fault. To NE it passes into the Lublin Basin (LB) along a narrow zone clearly reflected in the Middle Devonian depositional pattern. It was probably related to a basement fault along the axial part of the Radom-Kraśnik Elevation affecting deposition at least since the late Emsian onwards. BL continued to the Lviv Basin in SE, which was bordered from the east by the continental Ukrainian Massif. The Early Devonian stage of the basins development started in the latest Silurian with an open-shelf sedimentation passing in the middle to late Lochkovian into marginal marine elastics. This is (partly unconformably) overlain by a thick alluvial complex. Between late Emsian and early Frasnian rapid sedimentation of carbonate-terrigenous open-marine facies in the ŁRB was controlled by basement blocks subsidence. On the other hand, under stable cratonic conditions of the BL much smaller accomodation space was generated mainly by eustatic transgressions allowing a mostly shallow-shelf and carbonate platform development. In the Middle Frasnian this pattern was overprinted by a subsidence pulse related to the initial Pripyat Graben rifting. The Famennian stage was marked by a depocentre development in the central LB segment, and an accumulation of nearly 2 km of sediments, starting with carbonate-shaly deposits of a shelf basin and open shelf, passing upwards into marginal-marine and continental systems prograding SW-wards. The depocentre formed in a pull-apart regime between the Kock and Ursynów-Kazimierz faults, parallel with the main phase of the Pripyat Graben rifting.

The aim of this paper is to present the diagenetic processes occurring within lacustrine chalk and ooze in Holocene deposits from northwestern Poland. The analysed samples came from the Tarda (Iława Lake District) and Suliszewo (Choszczno Lake District) sites. For the purpose of mineral composition determination, both modern and classic (thermal analysis) research methods were applied. Composition analysis on a microprobe (Scanning Electron Microscopy) and X-ray structural analysis (Powder X-ray Diffraction) were used. Effects of early diagenesis processes (eodiagenesis) are observed in these sediments. The most important diagenetic processes include dissolution of carbonate minerals, pyrite and quartz. An important role was also played by pyritization and formation of early carbonate cements. Compaction occurred only on a small scale. Moreover, the sequence of the diagenetic processes was reconstructed. The earliest diagenetic process that occurred within the lacustrine chalk and ooze was the formation of micritic cement and pyritization. Successively, the whole sediment was undergoing dissolution processes, followed by compaction. After dehydration and drying of the samples, gypsum and halite crystallized from the pore waters.

The right to geological information is a valuable geological law subject and it is asset of property. On the ground of geological and mining law, geological information, including documentation and geological concessions, constitutes geological-mining assets. The author characterizes the right in the subjective and objective approach and in terms of the content of the law. The new law of 09 June 2011 introduces significant changes to the definition of the geological information, regulation and execution of this right. The paper points to a new statutory resolution and attempts to provide interpretation.
