Opis:
The highest Bulgarian mountains Rila (2,925 m a.s.l.) and Pirin (2,914 m a.s.l.) provide virgin mountain landscapes, intensive natural processes and a sharp sensitivity on natural and human impacts. The present paper focuses on the existing natural indicators for changes in climate during the last few centuries in the areas around the highest peaks Musala (the Rila Mountains) and Vihren (the Pirin Mountains), and the accent is put on the past and present existence of embryonic glacier forms. Dynamics of perennial ice bodies in the Pirin and the newly found fresh moraine ridge on the bottom of the Ledeno ezero Lake (the highest lake in the Rila Mts.) as well as the data from instrumental and historical records suggest a general trend of warming since the first two decades of the 20th century, especially expressed in the last 30 years. Inter-annual size variations of perennial ice bodies are found to be closely related to fluctuations of air temperature. Regional comparative studies show that perennial ice bodies in Bulgarian mountains are less sensitive to slight climate fluctuations than some other similar features in the Carpatho-Balkan area. Proper interpretation of these and future research results requires their incorporation in regional studies within the entire Carpatho-Balkan area.

Opis:
The Crimean Mountains (CM) are regarded as part of the Alpine-Himalaya orogenic belt related to the collision of the Eurasian and African plates. Our research in the CM has allowed confirming the existence of at least two flysch formations of different ages: the Taurida Flysch Formation (Upper Triassic/Lower–? Middle Jurassic) and the Sudak Formation (uppermost Jurassic/Lower Cretaceous) in the western and eastern sectors of the CM, respectively. After the Middle Jurassic volcanism, the freshwater claystones with coal-bearing intercalations, as well as local alluvial fan conglomerates were deposited. Then, following the Oxfordian/Kimmeridgian marine transgression, three separated Tithonian/Berriasian carbonate platforms developed: Baydarska, Chatyr-Dag and Demerji/Karabi. At the turn of the Late Jurassic, the deep-water Sudak Basin (eastern sector of the CM) began to develop in the eastern periphery of the Demerji/Karabi carbonate platform. This basin, dominated by turbiditic deposition, was probably connected with the Great Caucasus sedimentary system. Finally, distal flysch sedimentation in the Sudak Basin was followed by debris-flow deposits, with huge blocks of Upper Jurassic limestones. These blocks were derived from destruction of the Karabi carbonate platform. During the Berriasian/Valanginian, the eastern sector of the CM began to subside. As a result, both carbonate platforms (western CM) and the debris flow fans of the Sudak Basin (eastern CM) were overlain by marly shales and/or distal turbidites. This type of deposition lasted until the Aptian/Albian. In the post-Albian period, the Alushta-Salgir tectonic zone was transformed into a SE-dipping thrust fault with at least 10 km amplitude of overthrusting.

Opis:
The paper presents a method enabling determination of the extent of landscape zones, based on the criterion of area coverage by vegetation. This method made it possible to objectively determine the extent of landscape zones both in the entire Tatra Mts. and in their particular parts. The altitude, at which dominant type of vegetation changes, is considered to mark the boundary of a landscape zone. Boundaries distinguished in this way in the Tatra Mts. are presently situated at: 1,510 m a.s.l. (forest zone), 1,730 m a.s.l. (subalpine zone), and 1,880 m a.s.l. (alpine zone).

A set of geophysical methods were implemented in the research conducted on permafrost of the Tatra Mountains and the Abisko area, Northern Sweden. Results of geophysical surveys show evidence of permafrost in both areas. Comparative studies on the occurrence of permafrost in the Tatras and in the Abisko area indicate that contemporary active as well as fossil permafrost might occur in both locations. Results of the electric resistivity, electromagnetic, shallow refraction seismic, and ground penetrating radar methods reveal similar results and might be successfully used in indirect research on permafrost in the mountainous regions.

Opis:
The purpose of the report is to determine trends in thermal conditions in the Polish part of the Tatra Mountains. The study makes use of the data from the weather stations in Zakopane and on Kasprowy Wierch Mt. from the years 1951–2006, and mainly from 1966–2006. Various thermal characteristics were considered. The increase of the rate of upward trend in temperature in the Tatras at the turn of the 21st century, as well as the change of the seasonal distribution of the warming in comparison with the preceding long-term periods, have been documented. In 1966–2006, significant trends in the changes of the mean, maximum and minimum temperatures have been observed in the Tatras in summer (respectively, 0.04, 0.05 and 0.03–0.04 centigrade per annum). Certain symptoms of increase of the thermal continentality have also been observed (increase of the annual amplitude of temperature). Besides, important features of changes in thermal conditions at the turn of the 21st century include an increase in the number of hot days, and even appearance of the very hot days at the foothills of the Tatras, increase of the number of frost days and decrease of the number of ice days in the high mountain part of the Tatras, as well as increase of accumulated heat of the growing season and an increase of daily amplitude of temperature across the entire profile of the Tatras.

Opis:
Geomorphological and geological data collected over many years suggest at least eight episodes during which the Tatra Mts. were glaciated during the Quaternary. Evidence of glaciers can be found both in the Slovakian and Polish parts of the mountains as glaciofluvial deposits located at different altitudes, and in some cases also as terminal and lateral moraines. There are no moraines for the three oldest glaciations, Biber, Donau and Günz, maybe as a result of less intense development of glaciers. During the Mindel (Sanian 2) Glaciation the glaciers occuped a larger area in the High Tatra Mts. in comparison to the Western Tatra Mts., whereas during the succeeding younger pre-Riss (Liviecian) Glaciation their development was more restricted. A greater extent of the Tatra Mts. glaciers occurred again during the Riss I (Odranian) Glaciation, while they were less extensive during the Riss II (Wartanian) Glaciation. During the Würm (Vistulian) Glaciation the glaciers were surprisingly large. This might have resulted from many factors, including changes in atmospheric circulation responsible for the distribution of precipitation, as well as changes in the position of the permanent snow limit due to climatic changes and/or neotectonic movements. Glaciers finally retreated from the Tatra Mts. by the end of the pre-optimal part of the Holocene.

Opis:
Ground penetrating radar (GPR) surveys were conducted on both the glaciers and their forefields in the Tatra Mountains, Northern Scandinavia and on Spitsbergen – between the 49 degrees and 77 degrees latitudes. The results show that the glacial and periglacial environments interpenetrate. Permafrost is present in the glacier, and glacial ice may occur in the periglacial environment. What is common for both the environments is the perennial melting point surface, with the temperature close to 0°C. In the glacier it is the boundary of the cold-temperate transition surface and on the forefield – permafrost base.

Themicropalaeontology of the "Raibl Beds" of the Košuta Nappe in the western KaravankeMts., Slovenia, is described. The presence of the conodont apparatus of Nicoraella? budaensis Kozur and Mock is demonstrated and together with other fossils it confirms a Carnian age. A comparison of the Nicoraella skeletal apparatus with two other Triassic apparatuses is made. The benthic foraminifera Aulotortus sinuosus, A. tumidus, Prorakusia salaji, Pilamminella kuthani and Endothyra kuepperi are recognized. Their stratigraphical range corresponds to the foraminiferal Pilamminella kuthani Interval-Zone. Altogether the palaeontological content of an 85 m-thick section in the upper part of the "Raibl Beds" below Mt. Jepca is described. The diverse fossil content of this section contributes to the intercalibration of Upper Triassic conodont, foraminifer and dasyclad zonations.

Opis:
Geodynamical investigation in the Pieniny Mountain (south of Poland) were carried out since the 1960s. They contained levelling, gravimetric measurements and distance observations in horizontal network. The results reveled vertical and horizontal movements of the crust and periodic changes in gravity. In 1994-1995 horizontal network was adapted to perform GPS observations and they were carried out with leveling, gravimetric and EDM observations. In 1990s, the Dunajec river dam and the water resorvoirs in Czorsztyn and Sromowce Wyżne have been built. This has a new aspect in investigations releted to the effect of tectonic movements on the dam. Taking that into account, the study was revived, after six year break, in 2001. The investigations, which contain GPS, gravimetric and leveling observations, have been carried out every year. In this paper the result of horizontal displacement obtained from GPS measurement as well as gravity changes in 1994-2010 period are presented and yields linear trend in north-east direction less than 1 mm/year.

Results  show some differences in the vertical distribution and of examined radionuclides and metals. The change of  activity of 137Cs in the  soil samples depends mostly on the soil volume density and on the concentration of organic material. The state of "zero" 137Cs activity was developed in the form of maps.

Opis:
Large and medium karstic springs in the Polish Tatra Mts. occasion ally sampled during low flows exhibited little scatter of stable isotope composition and distinct differences between particular sampling sites. For extreme stable isotope values of four springs, the recharge altitudes were estimated by making use of topographic and geological maps. The altitude effect found in that way served for determining the recharge altitudes of other sampled sites. The altitude-effect gradients found in that way are -0.21‰/100 m and-1.45‰/100 m for delta exp.18 O and delta exp. 2 H, respectively. In general, large karstic springs (exsurgents) have the highest recharge altitudes whereas medium spring and deep wells are characterized by much lower altitudes. Tritium data interpreted with the aid of lumped parameter models yielded mean ages of ca. 3 years for low flows in large karstic springs, ca. 10 years for medium springs, and 50 to 100 years for deep wells, all with very wide age distributions. For four deep wells, the regional hydraulic conductivity estimated from tritium ages (0.8 ´ 10-6 m/s) is about 20 times lower than the geometric mean found from pumping tests (17 ´ -10–6 m/s) suggesting the existence of obstacles to regional flow.

Opis:
During the Triassic/Jurassic boundary interval and in the Jurassic, the Triassic carbonate platforms occupying the northern shelf of the Western Tethys were subjected to disintegration. Record of these processes in the Alpine-Carpathian area is incomplete and contains a number of stratigraphic gaps. In the High-Tatric succession of the Tatra Mountains (Central Western Carpathians) stratigraphic gaps expressed by unconformity surfaces occur between the Triassic and the Middle Jurassic. In particular areas, the Triassic is directly overlain by the Dudziniec Formation (Sinemurian-Bajocian), the Smolegowa Formation (Bajocian), the Krupianka Formation (Bathonian) or the Raptawicka Turnia Formation (Callovian-Hauterivian). The occurrence of Bajocian and Bathonian deposits is limited to isolated lenticular bodies or to infillings of neptunian dykes penetrating the Triassic. Spatial relations between particular Jurassic lithosomes and the occurrence of stratigraphic gaps between particular units allow discerning four main unconformities. In the stratigraphical order these are: base of the Dudziniec Format ion (erosional unconformity), base of the Smolegowa Formation (penacordance or parat conformity), base of the Krupianka Format ion (erosional unconformity) and base of the Raptawicka Turnia Formation (drowning unconformity). Following episodes of erosion modified the previously developed unconformity surfaces, which resulted in complex modern architecture of the Triassic/Jurassic contact, as well as between particular Jurassic formations.

Opis:
The lower-middle Upper Triassic succession of the Fatricum domain from the Tatra Mts is commonly called the Carpathian Keuper. During Late Triassic, the Fatricum Basin was a proximal part of the central Inner Carpathian Basin. In early Carnian times, carbonate sedimentation stopped. Emersion of the Middle Triassic carbonate platform resulted in development of palaeokarst and pedogenic fabrics and deposition of conglomerates. Typical Carpathian Keuper sediments – variegated shales with intercalations of sandstones and dolomites represent mixed continental/shallow marine environments. Variegated mudstones with pedogenic carbonate concretions and intercalations of thin sandstone beds originated in mudflat environment under the semi-arid climate condition. Thick-bedded, cross-stratified sandstones with common plant debris represent fluvial deposits. They were deposited during the periods of climate pluvialisation. According to ?13C and ?18O data, thick, continuous dolomitic sediments containing local cherts represent marine sediments of perilittoral environments, which were commonly emerged as evidenced by common palaeokarst and palaeosols featuring these complexes. Cyclicity in the lower part of the Carpathian Keuper resulted from climatic changes, whereas dolomite-clastic cycles from the upper part of the succession were generated probably by sea level fluctuations. Moreover, deposition of the Keuper succession was controlled by synsedimentary tectonic which resulted in big facies variability.

Opis:
Background Thermoluminescent detectors, type MTS-6, containing isotope ⁶Li (lithium) are sensitive in the range of thermal neutron energy; the ²³⁹Pu-Be (plutonium-and-beryllium) source emits neutrons in the energy range from 1 to 11 MeV. These seemingly contradictory elements may be combined by using the paraffin moderator, a determined density of thermal neutrons in the paraffin block and a conversion coefficient neutron flux to kerma, not forgetting the simultaneous registration of the photon radiation inseparable from the companion neutron radiation. The main aim of this work is to present the idea of calibration of thermoluminescent detectors that consist of a ⁶Li isotope, by using ²³⁹Pu-Be neutron radiation source. Material and Methods In this work, MTS-6 and MTS-7 thermoluminescent detectors and a plutonium-and-beryllium (²³⁹Pu-Be) neutron source were used. Paraffin wax fills the block, acting as a moderator. The calibration idea was based on the determination of dose equivalent rate based on the average kerma rate calculated taking into account the empirically determined function describing the density of thermal neutron flux in the paraffin block and a conversion coefficient neutron flux to kerma. Results The calculated value of the thermal neutron flux density was 1817.5 neutrons/cm²/s and the average value of kerma rate determined on this basis amounted to 244 μGy/h, and the dose equivalent rate 610 μSv/h. The calculated value allowed for the assessment of the length of time of exposure of the detectors directly in the paraffin block. Conclusions The calibration coefficient for the used batch of detectors is (6.80±0.42)×10⁻⁷ Sv/impulse. Med Pr 2017;68(6):705–710
