Opis:
The paper presents the first example of Holocene faults in the OuterWestern Carpathians in Poland. Small-scale normal faults at Koninki, Gorce Mts., cut both Palaeocene strata of the Ropianka Formation of the Magura Nappe and overlying coarse-clastic bedload facies of Holocene alluvium that builds a 5-5.5-high terrace step of a small valley. These NE-trending faults are accompanied by reorientation of clast a-b planes subparallel to fault planes and by clast fracturing. Such deformations must have been induced by relatively strong earthquakes, unknown from historical record of the Outer Carpathian seismicity. Fault attitude points to NW-oriented axis of the minimum principal stress, which is compatible with parameters of the present-day stress field in the Outer Western Carpathians of Poland.

Opis:
Sulfate mineralization occurs in almost all lithostratigraphic beds of the Carpathians and has been described for at least the last century. While carrying out cartographic studies near Bobowa, a new site of gypsum mineralization was discovered within the hieroglyphic beds of the Jankowa anticline. The gypsum crystals found there reach up to several centimetres in length and, so far, no similar ones have been described in the Carpathian flysch deposits. Gypsum from Jankowa occurs in the form of intergrowth and twinnings, rosettes and larkspurs, and vein fillings.

Opis:
The Biały Dunajec Valley is one of the large, meridionally oriented valleys cutting the Podhale Synclinorium. The tectonic origin of this valley has been suggested since the beginning of the 20th century. A large fault zone with an azimuth of about 20° has been recognized here. This zone extends to the north and cuts the Pieniny Klippen Belt, which is significantly lowered in its eastern side. The southern part of the Biały Dunajec fault zone (SBD) extends probably into the Tatra Massif (into the Mała Łąka Valley area and far to the south into the border of the Koszysta elevation and the Goryczkowa depression). The majority of faults constituting the SBD were formed during the initial phase as strike-slip faults; they were reactivated later as dip-slip faults with a prevailing dip-slip, mainly normal component. As a whole, the SBD is a scissor-like fault: in the northern part, near the Szaflary village, downfaulted is its eastern block, whereas in the southern part - its western block.

Opis:
Identification of hydrocarbon accumulation boundaries within an oil field area is an important factor for making decisions whether or not to drill out and develop the field, or to give up extraction in some parts of the areas. As an example, two gas/condensate fields in the Devonian strata of the Western Carpathians are presented in this paper. These deposits were found at various depths in the Miocene basement in two separate tectonic blocks. Boundaries of the Stryszawa field were identified with the traditional Horner method and with the modern log-log method on the basis of industrial data obtained with DST and production tests. Based on the analysis of the drilling-up and testing methods used in the L-4 well in the Devonian strata of the Lachowice field the authors formulated the causes of considerably lower inflow of reservoir fluid to the tester during four DST tests, and the inability to determine boundaries of this part of the deposit.

Opis:
Analysis of deposition rate were performed for synthetic sections, representing the upper Jurassic to lower Miocene sedimentary fill of the Western Outer Carpathian (WOC) basins. Calculated deposition rates differs in a range of a few orders of magnitude. During Tithonian to Berriasian-early Valanginian tectonic activity of the source areas supplying the Silesian Basin was related to the mechanism of syn-rift extensional elevation and erosion of horsts. General decay of source area activity in Valanginian to Cenomanian time was caused by regional post-rift thermal sag of the WOC. The Barremian to Albian phase of compressional uplift of the source area located north of the WOC lead to increase of deposition rate in some zones of the WOC basin. In Turonian to Paleocene time thick-skinned collision and thrusting took place south and south-west (in the recent coordinates) of the Silesian Basin causing very rapid, diachronous uplift of this zone, referred to as Silesian Ridge, resulting with high deposition rate in the Silesian Basin. At that time supply of sediments to the Magura Basin from south was relatively low, and the Pieniny Klipen Belt was presumably zone of transfer of these sediments. In Eocene the zone of collisional shortening in the WOC system was relocated to the south, causing rapid uplift of the Southern Magura Ridge and intense supply of detritus to the Magura Basin. Thrusting in the Southern Magura Ridge and collisional compression resulted with flexural bending of its broad foreland, being the reason for decrease of activity of both the Silesian Ridge and the source area at the northern rim of the WOC. The Eocene evolution of the Silesian Ridge is interpreted as controlled by both episodic tectonic activity and eustatic sea level changes. Contrasting development of the Southern Magura Ridge and the northern rim of Central Carpathians during Eocene stands for a palaeographic distance between the two domains at that time. During Oligocene and early Miocene a significant increase of deposition rates is observed for the basin in which sediments of the Krosno beds were deposited. This was caused by tectonic uplift of the source at the northern rim of the WOC, as well as the Silesian Ridge and the partly formed Magura nappe. The Miocene molasse of the WOC foredeep basin is characterised by notably higher maximum deposition rates than ones calculated for the flysch deposits of the WOC.

Opis:
The Orava-Nowy Targ Basin is the only intramontane basin in the Carpathian Mountains, where numerous low and raised peat bogs developed in the Holocene. The peat bogs were originally comprising about 40% of the basin area. to became confined to 12%, in result of several centuries of exploitation of peat. On the basis of investigations on geomorphological location of the preserved relics of peat bogs, and reconstructions of their original extent, an attempt was made to identify natural environment factors which had the biggest influence on development of peat-forming process within the Orava-Nowy Targ Basin. The most important of these factors were found to be landforms of fluvioglacial and fluvial accumulation and their composition, as well climatic conditions. However, it should be stated that distribution of raised peat bogs appears to be mainly controlled by the mode of circulation of shallow groundwaters and location of their stable outflows. This is an aspect of development of peat bogs that has not been studied up to now.
