The previous study showed that the Zechstein (Upper Permian) anhydrites have about 0.2% strontium with a remarkably small sample scatter. Our study of three lower Zechstein anhydrite units (Lower Anhydrite, Upper Anhydrite and Basal Anhydrite) from West Poland indicate that although often the Sr content is 0.1-0.2%, there are common deviations. In particular, a considerable part (28%) of the studied samples is characterized by lower values (<0.1%), and on the other hand ca. 15% of samples are Sr-enriched, and in those samples celestite was recorded. Particular anhydrite levels differ especially in the frequency of samples showing great Sr content. The greatest variation was found in the Lower Anhydrite. This agrees well with the conclusion derived from the sedimentological studies indicating that there was the greatest differentiation of depositional environments during the deposition of the Lower Anhydrite. The Sr content is a good indicator of brine concentration during the gypsum precipitation and it seems that the subsequent gypsum-anhydrite transformation itself does not affect the strontium distribution. The histograms of Sr content in the Basal Anhydrite indicate a slightly higher brine concentration than it was during the Lower Anhydrite deposition, and the latter in turn was higher than brine concentration during the Upper Anhydrite sedimentation. Celestite veins are clearly diagenetic in origin. The form of celestite occurrence and the increased strontium content (1% or more) indicate an additional source of ions that occurred outside the anhydrite series. In the case of the Lower Anhydrite, the supposed additional source of Sr was related to aragonite-to-calcite transition and squeezing of CaCl2 brines from reefs into anhydrite series due to increased pressure. For the Basal Anhydrite this source could be related to brines derived from the Older Halite deposits. © 2010 Elsevier GmbH. Source

The paper presents results of SPINUA (Stable Point Interferometry over Unurbanised Areas) Persistent Scatterers Interferometry (PSI) processing chain to study Earth surface deformations along the SW coast of the Gulf of Gdańsk, along the SE part of the Baltic Sea. As the input for SPINUA techniques 40 descending ERS-1/2 SLC (Frame = 251, Track = 36) images from the period 1995-2001 has been used. The area of interest (AOI) includes few cities and several towns, villages and harbors. The low lying coastal areas of the SW part of the Gulf of Gdańsk are at risk offloods and marine erosion. The PSI results, however, did not reveal the presence of a regional scale, spatially consistent pattern of displacements. It is likely that any crustal deformations in the AOI simply do not exceed ±2 mm/year, which is the velocity threshold we assumed to distinguish between moving and non-moving persistent scatterers (PS). Importantly, for the most part the urban areas of the main cities (Gdańsk, Gdynia and Sopot) results show ground stability. Nevertheless, significant downward movements tip to several mm/year, are locally noticed in the Vistula river delta - alluvial plain system located in the coastal zone east of Gdańsk as well as in the inland area west of the Gdańsk city. Indeed, the highest subsidence rates (-12 mm/year) was observed in the Gdańsk petroleum refinery constructed on alluvial sediments. Thus the anthropogenic loading and consolidation of the recent deposits can locally be an important factor causing ground subsidence. Source

In June of 1843 Roderick Murchison visited Poland to overview local geology in order to fill the gap between the results of his Russian campaign (1840-1841) and the familiar geology of Western Europe. Recent examination of Murchison's hand-written "Journal" and field notebooks in the archive of the Geological Society of London allows a detailed reconstruction of his visit in the Polish territories. During the five-days "charge" across the Holy Cross Mountains the famous British geologist, accompanied by the outstanding Polish colleague Ludwik Zejszner, had collected plenty of observations that were later partly quoted in Murchison's monumental treatise about the geology of Russia (1845). Among the most important new findings is the identification of the Devonian sediments earlier included by Jerzy Bogumil Pusch (1833-1836) in the Formation of Übergangs Kalkstein und Breccie (Transitional Limestone and Breccia). Murchison's visit and its results are echoed in later papers by domestic scientists, particularly those by Zejszner. The latter was the first Polish student of the Holy Cross Mountains geology who extensively introduced chronostratigraphic units established by Murchison, including the Silurian and Devonian in particular.

Summary of cooperation between specialists from Polish Geological Institute-National Research Institute and the Geological Survey of Lithuania during the last 20 years (1990-2010) is presented in this paper. During several stages of work and investigations, they have gathered data and created common databases for the border zone, e.g. geosites database. Groundwater monitoring was organized and ini-tiated, analysis of satellite images was made in terms of land use changes. Different thematic maps, including maps of soil contamination by heavy metals, were performed, too. Additionally, the sites connected with Marshal Józef Pilsudski were described in detail, with the special attention to its geotouristic and nature values. These sites are very attractive from the landscape point of view and are characteristic by interest-ing geological conditions. These comprehensive studies have created a good base for the multidirectional cooperation of the Polish and Lithu-anian geologists. Such cooperation is in agreement with the European Union recommendation to introduce Principles of the European Territo-rial Planning Policy. The aim of this policy leads to the reduction of pollution and improvement of environmental conditions in Europe. Results of common studies were presented in several papers, including the Atlas - Geologyfor environmental protection and territorial planning in the Polish-Lithuanian cross-border area, 1:500,000.

The paper contains short biographies of three prominent Polish geologists, scientists, travellers and patriots of the Zuber family - Rudolf, Stanistaw and Andrzej, father, son and grandson. Main occupation of Rudolf was exploration of oil deposits. His experience was of high value for many oil companies and countries that made their development dependent on the oil industry. On his scientific journeys he reached every inhabited part of the world, excluding Australia. In Krynica, he discovered a unique water that is among the strongest alkaline acidic waters in Europe. He is also the author of a fundamental publication, titled Flysh and crude oil which was an important and classical geological work of those times. His son, Stanislaw Zuber, started his professional career from participation in oil exploration in the Baku (Azerbaijan) and East Caucasus regions. His exploratory work in Albania resulted in the discovery of the main oil fields in this country -Kufova-Lushnja, Murriz-Pekisht and Patos-Cakran-Selenica. He is presently regarded as the father of modem geology of Albania. Andrzej Zuber, son of Kazimierz, Stanislaw's brother and grandson of Rudolf was also involved in several activities abroad (Kenya, Brazil, Mexico, Thailand, India). His main interests were connected with investigations of the environmental logograms of the common, mineral and thermal waters. Among different hydrogeological problems, he put special attention to determination of the genesis and recharge areas of the Krynica mineral waters. It could be considered as the continuation of his grandfather's work. Source
