Limestones designated the Štramberk-type are the most common carbonate exotic clasts (exotics) embedded in the uppermost Jurassic–Miocene flysch deposits of the Polish Outer Carpathians. About 80% of stratigraphically determinable carbonate exotics from the Silesian, Sub-Silesian and Skole units (nappes) are of Tithonian (mostly)–Berriasian (sporadically Valanginian) age. A study of these exotics revealed eight main facies types: coral-microbial boundstones (FT 1), microencruster-microbial-cement boundstones (FT 2), microbial and microbial-sponge boundstones (FT 3), detrital limestones (FT 4), foraminiferal-algal limestones (FT 5), peloidalbioclastic limestones (FT 6), ooid grainstones (FT 7), and mudstones-wackestones with calpionellids (FT 8). Štramberk-type limestones in Poland and the better known Štramberk Limestone in the Czech Republic are remnants of lost carbonate platforms, collectively designated the Štramberk Carbonate Platform. Narrow platforms were developed on intra-basinal, structural highs (some of them are generalized as the Silesian Ridge), with their morphology determined by Late Jurassic synsedimentary tectonics. An attempt was made to reconstruct the facies distribution on the Tithonian–earliest Cretaceous carbonate platform. In the inner platform, coral-microbial patch-reefs (FT 1) grew, while the upper slope of the platform was the depositional setting for the microencruster-microbial-cement boundstones (FT 2). Microbial and microbial-sponge boundstones (FT 3), analogous to the Oxfordian–Kimmeridgian boundstones of the northern Tethyan shelf (also present among exotics), were developed in a deeper setting. In the inner, open part of the platform, foraminiferal-algal limestones (FT 5) and peloidal-bioclastic limestones (FT 6) were deposited. Poorly sorted, detrital limestones (FT 4), including clastsupported breccias, were formed mainly in a peri-reefal environment and on the margin of the platform, in a high-energy setting. Ooid grainstones (FT 7), rarely represented in the exotics, were formed on the platform margin. Mudstones-wackestones with calpionellids (FT 8) were deposited in a deeper part of the platform slope and/or in a basinal setting. In tectonic grabens, between ridges with attached carbonate platforms, sedimentation of the pelagic (analogous to FT 8) and allodapic (“pre-flysch”) Cieszyn Limestone Formation took place. The most common facies are FT 4 and FT 1. Sedimentation on the Štramberk Carbonate Platform terminated in the earliest Cretaceous, when the platform was destroyed and drowned. It is recorded in a few exotics as thin, neptunian dykes (and large dykes in the Štramberk Limestone), filled with dark, deep-water limestones. Reefal facies of the Štramberk Carbonate Platform share similarities in several respects (e.g., the presence of the microencrustermicrobial-cement boundstones) with reefs of other intra-Tethyan carbonate platforms, but clearly differ from palaeogeographically close reefs and coral-bearing facies of the epicontinental Tethyan shelf (e.g., coeval limestones from the subsurface of the Carpathian Foredeep and the Lublin Upland in Poland; the Ernstbrunn Limestone in Austria and Czech Republic). Corals in the Štramberk Limestone and Štramberk-type limestones are the world’s most diverse coral assemblages of the Jurassic–Cretaceous transition. The intra-basinal ridge (ridges), traditionally called the Silesian Cordillera, which evolved through time from an emerged part of the Upper Silesian Massif to an accretionary prism, formed the most important provenance area for carbonate exotic clasts in the flysch of the Silesian Series. They are especially common in the Lower Cretaceous Hradiště Formation and the Upper Cretaceous–Paleocene Istebna Formation. The Baška-Inwałd Ridge and the Sub-Silesian Ridge were the source areas for clasts from the Silesian and Sub-Silesian units (e.g., in the Hradiště Formation), while the Northern (Marginal) Ridge was the source for clasts from the Skole Unit (e.g., in the Maastrichtian–Paleocene Ropianka Formation).

Niniejsza praca omawia zagadnienie rewaloryzacji zabytków na terenie małych miast Podkarpacia, które jest regionem o dużym zasobie cennych zabytków dziedzictwa kulturowego. Oprócz większych miast, takich jak Rzeszów, Przemyśl, Krosno, Przeworsk czy Jarosław, na terenie Podkarpacia istnieją także mniejsze ośrodki o równie bogatej tradycji i walorach kulturowych. W miastach tych niejednokrotnie znajdują się cenne obiekty o ponadprzeciętnych wartościach, które należy otaczać troską, a ich historię przekazywać lokalnym społecznościom. W publikacji zaprezentowano dwa przykłady obiektów zabytkowych, których rewaloryzacja przyniosła miastu wymierne korzyści w postaci podniesienia rangi najważniejszych obiektów w mieście, a także zaszczepienia świadomości i lokalnego patriotyzmu wśród jego mieszkańców. Omówione przykłady interwencji konserwatorskich dobudowy wieży do zabytkowego ratusza oraz rewaloryzacji budynku Towarzystwa Gimnastycznego „Sokół” pochodzą z Sieniawy, miasta położonego na terenie powiatu przeworskiego. Są one przykładem prawidłowej dbałości właścicieli i użytkowników obiektów zabytkowych o ich stan techniczny. Władze miasta oprócz obowiązku, jaki nakłada na nie jako na użytkowniku i właścicielu obiektu zabytkowego ustawa o ochronie zabytków i opiece nad zabytkami, zwracają uwagę lokalnej społeczności na potencjał, tradycję i historię miasta, a także dążą do przywrócenia najważniejszym obiektom i przestrzeniom publicznym w mieście właściwego wyglądu i rangi. Należy mieć nadzieję, że także inne miasta Podkarpacia o bogatym zasobie dziedzictwa kulturowego wezmą przykład z działań realizowanych na rzecz ochrony i rewaloryzacji zabytków w Sieniawie.

This article addresses the issue of monument revalorization in small towns of Podkarpacie which is a region with valuable cultural heritage. Besides larger cities such as Rzeszów, Przemyśl, Krosno, Przeworsk or Jarosław, in the area of Podkarpacie there also exist smaller towns with equally rich traditions and high cultural values. Those towns can frequently boast precious objects representing more than the average value, which should be taken care of, and their history popularized among local communities. The article presents two examples of historic buildings whose revalorization gave the town concrete benefits in the form of upgrading the rank of the most important objects, as well as instilling the awareness and local patriotism among its inhabitants. The examples of conservation interventions discussed below namely: addition of the tower to the historic town hall and revalorization of the building of The „Sokół” Gymnastic Association come from Sieniawa, a town located in the Przeworsk County. They represent proper care which owners and users of historic buildings should take about their technical condition. Apart from the obligation imposed on them as the user and owner of the historic object by the Heritage Protection Act, town authorities draw the attention of the local community to the potential, tradition and history of the town, as well as aim at restoring the crucial objects and public spaces in the town to their proper appearance and rank. It is to be hoped that other towns in Podkarpacie with rich cultural heritage will also imitate the activities geared towards heritage protection and revalorization which are currently realized in Sieniawa.

The investigation of phenomena, influencing the short time variation of gravity, has gained importance with the increasing accuracy of gravity meters. Accordingly, we have studied vertical surface movements, attributable to two effects: compaction of sediments, on the one hand, and structural movements, on the other in the young sedimentary Pannonian Basin. ln most of the deep sedimentary regions positive correlation can be found between sediment thickness and subsidence. As a consequence of subsidence, observation pointsof the surface get into a different equipotential level of the Earth's gravity field. Calculating the effects of the vertical surface movements, determined by repeat levelling, for a 10-year time span, the variation of gravity io general should be about 3 μGal (1 μGal = 10-8m/s2), but at special places it may reach as much as 10-20 μGal.

The data come from samples from the archaeological site Včelince (Slovakia). It is a settlement of a multicultural character. The stratigraphy of the layers VII .I assigns chronological sequence: the Hatvan culture, Hatvan-Otomani Horizon of the Hatvan culture, Otomani/Füzesabony culture circle, the Koszider Horizon, Piliny culture. There were applied animal bones for the samples of 14C. They came from the pits as well as from the layers dated by typology, horizontal and vertical stratigraphy. The 14C data confirm the chronological order indicated by the stratigraphical observations in the site. It is the very first 14C measurement in the case of the Hatvan culture in Slovakia. Mesurment of the earliest layer of the Hatvan culture in Včelince provides the data (Bln 5560: 3710š38 BP) which is comparable with the data of the earliest Hatvan culture in Hungary. A part of the teritory of Slovakia can not be excluded from the process of its origin also in spite of the data mentioned above. As the dates are coming from tratigraphically and typologically clearly defined contexts, they are of high importance for the Bronze Age archaeology of the region.
