Content available remote Grave of the Corded Ware culture from Węgrzce, Kraków District
EN
Grave 3/2016 from site 3 in Węgrzce, Comm. Zielonki, Kraków District was discovered during archaeological excavations preceding construction of a detached house. This was a niche grave, holding two burials: a male aged 38–47 years, and a child 4–5 years old. The recorded funeral rite is characteristic of a cluster of Corded Ware culture cemeteries on the lower Dłubnia River, near Kraków. A vessel recovered from the grave reveals local features characteristic of that cluster. One radiocarbon age determination was obtained for the burial, pointing to ca. 2470–2350 BC as the most likely range. Thus, the grave links with the younger phase of the Final Eneolithic in Lesser Poland.

Integracja Polski z Unią Europejską powoduje konieczność zharmonizowania przepisów krajowych z przepisami europejskimi. Wymagania jakościowe złączy spawanych w mostach stalowych wg nowych zaleceń przedstawili autorzy w 11 publikacjach wydanych w latach 2002÷2017. Określone tam wymogi normowe w wielu przypadkach poddano krytycznej ocenie. Próbę rekapitulacji zaleceń konstrukcyjno-projektowych oraz badawczych, dotyczących złączy spawanych w mostach, przedstawionych w tych publikacjach omówiono w artykule.

The integration of Poland with the European Communities induced the necessity for harmonization of national regulations with European ones. Quality requirements for welded joints in steel bridges were presented by the authors in 11 articles published in the years 2002÷2017. Standard requirements given there were subjected to critical remarks in many cases. The effort for recapitulation of structural and research recommendations for welded joints in bridges are presented in this paper.

Red sand dunes occur in the coastal plains of south east and west of Tamil Nadu, India be-tween the co-ordinates of 8°00’ to 9°30’ N; 77°18’ to 79° 00’ E. OSL dating of these sands indicated aggradations between ~16-9 ka and ~9-3 ka in the west and east coasts respectively. Dating results from inland red dunes at the foothills of Western Ghats show a break in deposition at ~6 ka and ag-gradation since ~2 ka. The sand aggradations in the west coast occurred during the transition period when SW monsoon in the area was re-establishing. The dunes attained their stability by 9 ka. In the coastal region, the aggradations were controlled by sea level changes and a local recycling of earlier dunes (in the east coast). In the inland areas, the dune building was controlled by sand supply from fluvial sources.

Jurassic rocks in the central Tulsequah map area include conglomerates and interbedded fossiliferous finer clastics of the Takwahoni Formation (Laberge Group) which unconformably overlie Triassic rocks. Ammonite collections document the Pliensbachian, Toarcian and Bajocian stages. We refine the age and provenance of episodes of coarse clastic input and confirm the progressive change of dominant clast lithology from reworked sedimentary rocks above the Triassic-Jurassic unconformity to volcanic, plutonic and then metamorphic clasts in the Upper Toarcian. The uppermost coarse clastic unit is a Bajocian chert-pebble conglomerate which, along with the immediately underlying black mudstone, we include in the Bowser Lake Group. Together with regional correlations, this confirms that the age of the basal part of the Bowser Lake Group is diachronous, younging southwards into Stikinia. Sandstone petrofacies trends and changes in conglomerate clast composition indicate arc uplift and dissection followed by Middle Jurassic orogen recycling. The isotopic ages of detrital zircons and granite clasts compared with the biochronologically constrained ages of the enclosing strata suggests that processes of intrusion, arc uplift, unroofing, and clastic deposition during the Early Jurassic occurred over intervals of significantly less than five million years.

The paper presents new and important 14C data from eight Eneolithic sites in Campania measured at the Centre for Isotopic Research of Cultural and Environmental Heritage (CIRCE) AMS laboratory in Caserta (Italy). Twenty-four 14C determinations on bone and charcoal are used here for chronological reconstruction of human habitation and dating of some volcanic eruptions affecting the settlement activity. Our research has shed new light on absolute chronology of the whole Campanian Eneolithic, a period of profound cultural transformations triggered by introduction and use of metals, in particular copper.

Determining the age of glacial and glaciofluvial deposits is necessary to better under stand the deglaciation of north eastern Po land. Cosmogenic 36Cl, accumulated in boulders and matrix, suggests that in heritance and erosion affect cosmogenic inventories and must be taken into account when calculating exposure ages of land forms. A simple approach to detect and distinguish between the two effects, by comparing the inventories of 36Cl in boulders and matrix, allows us to compute appropriate corrections to apparent (uncorrected) ages and to determine model (corrected) exposure ages of the deposits. Apparent cosmogenic 36Cl ages fall in the range between 11 ky and 28 ky (1 ky = 1000 calibrated 36Cl years), pointing, correctly, to the end of the last glaciation, and correlate with oxygen isotope stage 2 (OIS 2). Model ages of glacial and glaciofluvial depos its fall into one of three time intervals. The oldest erratics, 27-28 ky (Kruszki and Bachanowo 1), date the advance of the Weichselian ice sheet. They are older than the surrounding surfaces, which con firms the existence of nunataks during later phases of the last glaciation. The main belts of recessional moraines formed 19.7 š 1.0 ky ago (Gremzdy Polskie) and 17.9 š 1.3 ky ago (Łopuchowo 2 and Gulbieniszki), and the last ice melted 14.4 š 1.0 ky ago (Łopuchowo 1). Erosional terraces in the Czarna Hańcza valley were formed 14.7 š 0.9 ky ago (Bachanowo 2) and 14.4 š 1.0 ky ago (Bachanowo 3), probably by the melt waters from the last ice in the area. Our results suggest that different parts of the southern margin of the Fennoscandian Ice Sheet advanced and re treated independently, supporting the idea that the deposits at the southern margin of the Scandinavian Ice Sheet are not synchronous.

The Bayesian theorem provides mathematical base for probabilistic calibration of radiocarbon dates, but it is also a base for more sophisticated analysis - combining of probability distribution of calibrated radiocarbon dates with information from other sources – for example stratigraphic information or dates obtained by a method differ than radiocarbon dating. This paper presents three examples of using the method of combining radiocarbon and other information to study the chronologies of archaeological sites. The first example concerns the Inca State chronology and is an attempt to define the time intervals of Inca Imperial Phase and Inca Preimperial Phase accurately. The second refers to the settlement in Wolin and allows to assign the chronology to cultural layers excavated in Trench 6, Site 1 located in central part of settlement and to precise obtained results. The last example concerns South American site - Maucallcta and is a case, when application of the method does not give results because of ambiguity of stratigraphic information.

The Palpa Archaeological Project PAP investigates the relationship between the famous Nasca lines and ancient settlements in the Palpa region, in the desert of the south coast of Peru. Chronology will be fixed in absolute terms by radiocarbon dating of sites of Los Molinos and La Muńa. As a first approximation we get for the Nasca 3 culture 60-280 cal AD and for Nasca 4/5 and 5 culture 320-430 cal AD. That means the transition from Early to Middle Nasca is in the range between 280-320 cal AD.

Content available remote Research history on the Tatra Mountains glaciations
EN
In this paper, we provide a brief history of glacial geomorphologic research in the Tatra Mountains with a special focus on glacial chronologies. We provide critical comments on previously published glacial chronologies and identify relevant gaps in knowledge on Tatra mountain glaciations suggesting future challenges and the focus of scientific research. Distinct differences in applied methodologies, presented conceptions, and research paradigms over 160 years of research enable us to distinguish four phases of scientific research on Tatra mountain glaciation (pioneer phase, mapping phase, geochronological phase and meta-analysis phase). These four phases follow the universal sequence of glacial geomorphologic research history defined by P.D. Hughes et al. (2006) and P.D. Hughes and J.C. Woodward (2016) for Mediterranean mountain areas. In the last two phases, the glacial chronology was substantially supported with radiometric dating of landforms and sediments as well as paleobotanical data obtained from intra-moraine sites. The current meta-analysis phase of research provides dating techniques using terrestrial cosmogenic nuclide (TCN) exposure ages and glacier-climate modeling. The present-day TCN dataset for the Tatra Mountains includes 300 individual ages (10Be and 36Cl together). We underscore the fact that this dataset has substantially verified many key issues in the glacier geochronology of the Tatra Mountains. This is particularly true of the Last Glacial Maximum (LGM) – the Lateglacial chronology for which abundant datings are currently available and their number is still increasing. However, it is challenging to evidence the chronology and extent of the most extensive glaciation(s) (MEG).
