On the 28th of June 2017, the Polish Ministry of the Environment announced the boundaries of the tender areas selected for the third licensing round for concessions for prospection, exploration and exploitation of hydrocarbons. This round is going to be proceeded in the 4th Quarter of 2018 and 1st Quarter of 2019. The geologists of the Polish Geological Survey selected 15 tender areas (promising for discoveries of conventional and unconventional oil and gas fields) based on the geological data resources stored in the National Geological Archive, other published data, as well as the knowledge and experience of employees of the Polish Geological Institute - National Research Institute and the Polish Ministry of the Environment. All selected areas are located onshore. In this article we describe 10 tender areas located in the Gdańsk, Pomerania and Wielkopolska petroleum provinces. Other tender areas situated in the Carpathians (Błażowa, Proszowice W, Rudnik-Lipiny, Wetlina) and in the Lublin Petroleum Province (Ryki) will be discussed in the next publication. Three areas: Wejherowo, Bytów and Braniewo-Miłakowo are located in the northern Poland (Gdańsk Petroleum Province). The exploration targets of these areas are generally related to structural-lithological traps in the Middle Cambrian beds of the Baltic Basin, as well as to unconventional shale oil and gas in the Lower Paleozoic. Seven tender areas are situated in the northwestern Poland (Pomerania and Wielkopolska Petroleum Provinces). Three of them - Chodzież, Piła and Leszno are dedicated to conventional gas deposits in the Rotliegend sandstones and, in some cases, also oil deposits in the Zechstein/Main Dolomite. Excluding the Leszno tender area, chances for tight gas discoveries exist within the Rotliegend sandstones. The exploration target of the Konin tender area is related to possible conventional fields in the Jurassic and Lower Cretaceous beds. In the Pomerania region the exploration target is generally related to conventional hydrocarbon deposits in the Devonian, Carboniferous and Permian (Rotliegend and Zechstein/Main Dolomite). Three tender areas are situated within the region of: Sierpowo, Orle and Chełmno. As a rule, a concession is granted for a period of 10 to 30 years and is divided into 2 phases: 1) prospecting and exploration phase (which lasts from 4 to 5 years and can be extended to another 2-year period), 2) production phase. Every entity interested in obtaining a concession needs to undergo the qualification procedure. We believe that this publication will contribute to better understanding of the offered tender areas and encourage activity in the Polish oil and gas sector.

Magnetostratigraphy of the Keuper succession in the southern Mesozoic margin of the Holy Cross Mountains is presented based on investigations of two sections of Brzeziny and Wolica. They cut an ~60 m thick succession of variegated siltstones and claystones, which overlies the Reed Sandstone (Stuttgart Formation). The succession has been correlated with the Patoka Member of the Grabowa Formation, defined in the Upper Silesia region as an equivalent of the Steinmergelkeuper (Arnstadt Formation). The primary Late Triassic magnetization was obtained from component B carried by fine-grained haematite. Twelve magnetic polarity zones, six of normal and six of reversed polarity, have been defined. The obtained polarity pattern corresponds to the Norian (E13–E16 Newark zones) according to the Long-Rhaetian option of the Late Triassic Magnetic Polarity Time Scale. The mean normal polarity characteristic direction (N = 24, D/I = 31/62, k = 28.24, α95 = 6.04) differs significantly from the reversed one (N = 18, D/I = 223/-25, k = 16.38, α95 = 8.65): the primary magnetic signal is partly overlapped by component A carried by magnetite of recent viscuous remanent magnetization. Some samples do contain also coarse-grained haematite that, however, does not form any clustered magnetization. The palaeopole position calculated from the transposed reversed and normal polarity directions of component B corresponds to the Late Triassic (Norian) segment of the reference Baltica/Europe Apparent Polar Wander Path.

The paper presents the characteristics of prospective zones identified for the first time within the lower Palaeozoic shale formations occurring in the Baltic-Podlasie-Lublin Basin and within the Carboniferous shale, sandstone, and mixed shale-sandstone complexes (the so-called hybrid complexes) in the basin of south-western Poland. The lateral and vertical ranges of these zones are determined based on specific criteria using the results of various research methods and analyses, i.e.: stratigraphic, sedimentological, mineralogical, petrological and geochemical of organic matter, petrographic and petrophysical, including interpretation of well logs. Archived geological materials and those coming from the boreholes drilled recently in the concession areas were also used. Four prospective zones have been distinguished in the lower Palaeozoic of the so-called shale belt: SP1, SP2, SP3 and SP4. The most prospective area for the occurrence of unconventional hydrocarbon deposits in shale formations is the Baltic region – the Łeba Elevation, where there are all four perspective zones, only partially covering the range of potentially prospective formations. In each of these zones, both liquid and gas hydrocarbons can be expected in this area. Due to the low percentage of organic matter, the lowest hydrocarbon generation potential is attributed to the Lublin region. However, the low values of this parameter are compensated by other parameters, i.e. the considerable thickness and lateral extent of zone SP4 corresponding partly to the Pelplin Formation. In the Carboniferous rocks of south-western Poland, seven prospective zones have been distinguished in four borehole sections. Four of them are “tight” zones in compact sandstones, while the other three zones represent a hybrid type in complexes with mixed lithology. No prospective zones have been defined in complexes with homogeneous shale lithologies. Determination of lateral extents of the identified zones has not been possible due to the scarcity of data on the geological structure and stratigraphy of the Carboniferous succession in the study area

The paper deals with the age and palaeoenvironment interpretation of the Late Berriasian sedimentary transition from micritic calpionellid limestones to marls, corresponding to the passage from the Osnica Formation to the Kościeliska Marl Formation, Lower Sub-Tatric succession, Tatra Mts., Central Western Carpathians. Since only reliably dated sections are an appropriate basis for palaeoenvironmental study, the following pelagic and hemipelagic sections were chosen owing to enrichment in fine, clastic material and the existing biostratigraphic and magnetostratigraphic frameworks: Pośrednie III, Rówienka, Gładkie Upłaziańskie and Gęsia Szyja. The authors integrated and interpreted new, detailed data on magnetic susceptibility (MS), rock magnetism and element geochemistry from all of the sections. Well defined biostratigraphy permitted the testing of the potential of MS as a stratigraphic method. Owing to its close connection to selected terrigenous elements (e.g., Al, Th, Zr), MS could be used here as a proxy for detrital input into the basin. Its value as a correlation tool in a pelagic and hemipelagic setting was confirmed. MS permitted not only detailed correlation of the outcrops studied, but also the comparison of them with the Barlya section (Western Balkans) of the same age. This study proves that increased detrital input began in the Calpionellopsis simplex Subzone and continued into the lower part of the Calpionellopsis oblonga Subzone. It might be regarded as synchronous event within the Zliechov Basin and it is not everywhere correlated with the formation boundaries. The change in sedimentation was not only a local phenomenon. The onset of deposition of the terrigenous fraction can be identified in many sections of the Western Tethys. Two independent factors, regional regression and an increase in humidity might have contributed simultaneously to the increased detrital input in Late Berriasian time. However, this picture is further complicated by tectonic activity on local and regional scales.

Integrated bio- and magnetostratigraphic data from the Lower to Upper Berriasian of the pelagic succession at Barlya (Western Balkan, Bulgaria) are presented. The investigated interval, 24 m thick, covers the top of the Calpionella elliptica, Calpionellopsis simplex and Calpionellopsis oblonga subzones. Magnetozones from the upper part of M17r up to M16n were identified. The boundary between the Elliptica and Simplex subzones correlates with the lower part of M16r, while the boundary between the Simplex and Oblonga subzones is situated in the lower part of M16n. The magnetic susceptibility reveals an increasing trend from the middle part of M16r which accounts for the increasing supply of fine clastic sediments to the basin.

Palaeomagnetic measurements of polymetallic-uranium ore in the Old Uranium Kletno Mine were carried out. Thermal and alternating field (AF) demagnetizations of the rocks studied (fluorite and quartz veins, cataclased gneisses, calcareous-silicate rocks with epidote/grossular) enabled isolation of two well-defined magnetization components. A normal polarity palaeomagnetic direction was preserved in magnetite and coarse hematite, whereas reversed polarity is linked with fine hematite grains. Both statistically well-defined components do not differ within limits of error. The calculated mean palaeomagnetic pole was compared with the European apparent polar wander path. This comparison points unambiguously, within limits of statistical error, for an Early Cretaceous to Paleogene age of characteristic components of magnetization. Consequently this age limit constrains the time of uranium-bearing polymetallic-fluorite mineralisation.

Middle and Upper Juras siclime stones from the Polish part of the Pieniny Klippen Belt (PKB) were palaeomagnetically studied at six localities. The Middle Jurassic redcrinoidal lime stones of the Krupianka Lime stone Formation and Oxfordian radiolarites of the Czajakowa Radiolarite Formation, sampled in the eastern part of the Polish section of the PKB, were ei ther unsuitable for palaeomagnetic studies (Krupianka Klippe) or remagnetized in the Neogene (Baba and Zaskalskie-Bodnarówka klippen). The Czorsztyn Lime stone Formation was investigated at the localities of Krempachy (up per Mid dle Jurassic: upper most Bajocian?-Callovian?), Obłazowa (mid dle Oxfordian) and Rogoźnik (Rogoża Coquina Member- Kimmeridgian). A pre-folding, mixed polarity component of magnetization was revealed, which was interpreted as primary. Palaeoinclinations differ slightly, but not significantly, between localities. The palaeolatitude of the Polish sector of the PKB, averaged for the Middle/Upper Jurassic, amounts to 22°N (± 5°). It corresponds to the estimated palaeolatitudes of the northern margins of the Adriatic microplate and indicates a significantly large distance from the European plate. There is a growing evidence for a northward drift of the PKB in the Late Jurassic up to the earliest Cretaceous: from the palaeolatitude of 22°N in the Late Jurassic up to 28°N in the western part, in Po land/W Slovakia, and from 28° up to 36°N in the eastern part of the PKB in Ukraine. Systematically lower palaeolatitudes in the west combined with exsting palaeogeographic and geotectonic scenarios would account for a NE-SW orientation of the Czorsztyn Ridge in the Late Juras sic/earliest Cretaceous.

Middle and Upper Jurassic limestones from the Polish part of the Pieniny Klippen Belt were palaeomagnetically investigated. Samples were collected from four localities: Obłazowa Klippe (Czorsztyn Limestone Formation - Upper Oxfordian), Rogoźnik Klippe (Rogoża Coquina Member of the Czorsztyn Limestone Formation - Kimmeridgian), Krupianka Creek and Baba Klippe (Krupianka Limestone Formation - Upper Bajocian). During thermal demagnetization samples from Rogoźnik Klippe and Obłazowa Klippe indicate one distinct, high temperature component with normal polarity, an inclination ca 40° and a counterclockwise rotated declination of about 20° from the present north. Because the fold tests between Obłazowa and Rogoźnik are positive, we conclude that the obtained direction is pre-folding. Good quality data enable determination of the magnetic remanence age as Mesozoic, Late Jurassic or Early Cretaceous and a palaeolatitude calculation of 22 ± 5°. It might be compared to recently obtained data from the Ukraine section (Veliky Kamenets) of the Pieniny Klippen Belt (Lewandowski et al. 2005), where palaeolatitude for the Late Jurassic (Oxfordian) was estimated as 28 ± 6°. In Baba Klippe one direction with reversed polarity and steep inclination has been defined. Fold test was impossible because the layers are in a horizontal position, but we assume that it is secondary. Component with reversed polarity was acquired probably during thermal changes of rocks related to andesite intrusion (about 300 m to the south) of Sarmatian age. This direction resembles Neogene data with reversed polarity acquired from the Pieniny andesites (Birkenmajer & Nairn 1968; Marton et al. 2004).

Paleomagnetic and petrological analyses were performed on Devonian carbonate rocks from the Kielce region (Janczyce 1 borehole, Dule, Łagowica escarpment, Budy Quarry) in the Holy Cross Mts. Rock samples were selected from localities with different degree of thermal alteration, diversified lithology and stratigraphy. Investigated carbonates, excluding those from the Budy Quarry, revealed traces of the Early Permian remagnetization related to magnetite. The intensity of the Late Variscan remagnetization is linked to rocks affected by the second stage of dolomitization with increased thermal maturity in the northern part of the Kielce region. The magnetic signal is probably related to rocks’self-cooling, fixed as a result of the latest Carboniferous to Early Permian uplift.
