The study presents the results of a compre¬hensive analysis of radiocarbon and luminescence dates from samples taken from a fluvial environment for selected regions south of the LGM line, presented against a high-resolution INTIMATE stratigraphy. It is shown that discontinuous records of fluvial environmen¬tal responses in such an analysis reveal significantly more details than studies conducted at individual sites. A strong correlation is observed between peaks in the PDF curves of radiocarbon dates and interstadial periods, while accumulations of luminescence dates are corre¬lated with stadial periods.

The article is a commentary on the current state of knowledge of the formation conditions, origin and stratigraphic position of the „Middle Polish fluvial, fluvioperiglacial high terraces” being relief elements of the river valleys of the Kielce– Łagów Depression (KŁD) in the southern part of the Holy Cross Mountains (HCM), i.e. the Belnianka, Lubrzanka and Łagowica river valleys. The former conception and criteria of distinguishing them are no longer fully valid. The “high terraces” were formed in the studied valleys in periglacial conditions of the Vistulian Glaciation and not, as it was previously considered, during the “Middle Polish Glaciation”. They are entirely or partially composed of slope deposits or formed within the cover of glacial and / or slope deposits (toe-cut terraces) of different ages (including derived from the Odra Glaciation). Their hypsometric position is determined by the features of structural relief and the possibility of deposition of slope sediments on the alluvial series. The formation and structure of these terraces are the outcome of the location and pattern of river valleys in relation to the morphostructural elements of the KŁD as well as the changes of climate and environmental conditions in the Quaternary. The presented results were obtained owing to the fact that the investigations were conducted both in the profiles of hillslopes (slope environment) and river valleys (fluvial environment) as well as in the bottom of the KŁD (glacial environment). Only such an integrated approach gives an opportunity to find the relationship between the elements of the local litho- and morphogenetic system of the HCM: hillslopes ↔ river valleys ↔ bottoms of structural depressions.

Geopark Świętokrzyski to pierwszy Światowy Geopark UNESCO funkcjonujący w całości na terytorium Polski. Geopark położony jest w południowo-zachodniej części Gór Świętokrzyskich, na obszarze charakteryzującym się zróżnicowaną budową geologiczną, która odzwierciedla się także w specyfice rzeźby terenu. Ewolucja morfologiczna tego obszaru uwarunkowana została głównie zróżnicowaną budową litologiczną i strukturalną podłoża podczwartorzędowego oraz oddziaływaniem różnych procesów morfogenetycznych wynikających ze zmian klimatycznych zachodzących w kenozoiku. Obecne ukształtowanie terenu Geoparku stanowi wypadkową wszystkich tych uwarunkowań oraz antropopresji związanej m.in. z dawną i współczesną eksploatacją surowców mineralnych. W granicach Geoparku Świętokrzyskiego modelowym obszarem, na którym można obserwować te zależności jest Chęcińsko-Kielecki Park Krajobrazowy. Dziedzictwo geomorfologiczne rozumiane jako część dziedzictwa geologicznego związanego z formami ukształtowania terenu, decyduje o wysokim potencjale geoturystycznym tego obszaru. Praktyczne wykorzystanie tego potencjału dla zrównoważonego rozwoju społeczno-gospodarczego obszaru objętego granicami Geoparku jest przedmiotem działań realizowanych przez samorządy lokalne we współpracy z instytucjami naukowymi, organizacjami pozarządowymi oraz organami administracji publicznej.

The Świętokrzyski Geopark is the first UNESCO Global Geopark in operation situated entirely on the territory of Poland. The location of the geopark in the south-western part of the Świętokrzyskie (Holy Cross) Mountains makes it an area of exceptional geodiversity, which is also reflected in the specificity of the relief. The morphological evolution of this area was conditioned mainly by the diverse lithological and structural features of the Quaternary substrate and the impact of various morphogenetic processes resulting from climatic changes taking place in the Cenozoic. The current topography of the Geopark is the resultant of all these conditions and anthropopressure related to the past and present exploitation of mineral resources. Within the Świętokrzyski Geopark, a model area where these relationships can be observed is the Chęciny-Kielce Landscape Park. The geomorphological heritage, understood as part of the geological heritage related to the land relief, determines the high geotouristic potential of this area. The practical use of this potential for the sustainable socio-economic development of the area covered by the Geopark is the subject of activities carried out by local authorities in cooperation with scientific institutions, non-governmental organizations and public administration bodies.

This paper presents the Late Glacial stage of the development of the Białe Ługi peatland in the southern Holy Cross Mountains, based on a comprehensive palaeoenvironmental data. A complex analysis of palynology, Cladocera, sedimentology, geochemistry and 14C dating were used. Organic deposition was initiated during the Oldest Dryas. The sedimentary record of the aquatic and terrestrial ecosystems reflects considerable difference between cooler (Oldest, Older and Younger Dryas) and warmer phases (Bølling and Allerød). Periods of intensified interaction between Aeolian processes and peatland are related to stages of disappearing vegetation and changes in aquatic invertebrate communities. We therefore suggest that peatlands were created as a result of local lithological-structural, tectonic, hydrogeological and morphological conditions, and the peatland development rate was largely influenced by changing climatic conditions, which determined local vegetation development, intensity of denudation processes and water level changes. The results validate significance of selection and use of several methods, as well as value of biogenic deposits from the Białe Ługi peatland as archives of past climate change in the Małopolska Upland. Relatively stable water conditions and uninterrupted biogenic sedimentation in the Late Glacial that were provided by the geological structure and relief suggest the studied peatland is a leading one in the region.

The composition of the transparent heavy-mineral assemblages (0.25-0.1 mm) in Quaternary slope, karst, glacial, fluvioglacial and fluvial deposits with different parent material was investigated in the Kielce-Łagów Valley (the central part of the Palaeozoic core of the Holy Cross Mountains). For the purpose, 93 samples of mostly sandy sediments were examined. Some marker and some supporting minerals can be distinguished. Slope and karst deposits are dominated by the abrasion-resistant minerals zircon, tourmaline, staurolite and rutile. This assemblage points at a source consisting of strongly weathered pre-Quaternary bedrock. Glacial and fluvioglacial deposits are dominated by medium-resistant and non-resistant minerals (garnet, amphibole, pyroxene and biotite). The two types of parent material of the heavy minerals are typical of the Quaternary deposits in the Polish uplands. The two sources are most clear in the younger (Vistulian and Holocene), mostly fluvial sediments. The results of the analysis imply that the impact of Pleistocene glaciers on the central part of the Holy Cross Mountains was neither large enough to hide the local mineralogical background, nor sufficient to dominate over the main processes transforming the mineral composition under the variable climatic conditions of the Quaternary, including aeolian processes and chemical weathering.

The heavy-mineral assemblages of Pleniglacial fluvial sediments were analysed for two river valleys, viz. the Luciąża River (at Kłudzice Nowe) and the Belnianka River (at Słopiec). These sites, on the Piotrków Plateau and in the Holy Cross Mountains respectively, are located in different morphogenetic zones of Poland that were affected to different degrees by the Middle Polish ice sheets. The study was aimed at determining the kind of processes that modified the heavy-mineral assemblages in the two fluvial sediments, at reconstructing the conditions under which these processes took place, and in how far these processes caused changes in the assemblages. The heavy-mineral associations of the parent material was taken as a starting point; this parent material were the sediments left by the Odranian glaciation (Warta stadial = Late Saalian). It was found that heavy-mineral assemblages in the Luciąża valley deposits are varied, particularly if compared with other fluvioglacial Quaternary deposits from the Polish lowlands, with a dominance of garnet. In the fluvial deposits of the Belnianka valley, zircon, staurolite and tourmaline dominate, with minor amounts of amphibole, pyroxene, biotite and garnet. This suggests that the deposits were subject to intensive and/or persistent chemical weathering and underwent several sedimentation/erosion cycles under periglacial conditions. In both valleys chemical weathering and aeolian processes were the main factors that modified the assemblages of the transparent heavy minerals; these processes were largely controlled by the climatic changes during the Pleistocene.

Several possibilities to present and to interpret the results of granulometric analyses of Quaternary fluvial, aeolian, glacial and wash-out slope deposits were investigated. Attention is paid particularly to the cumulative curves at a probability scale and the frequency curves, and it is shown how these curves can help to determine the sedimentary environment. The inclination of the cumulative curves in the part of the maximum proportion of a particular grain size appears significant. It appears possible to obtain information on the density and dynamics of the transporting medium from the course of the cumulative curves (inclination and spread of grain size). The examination of textural parameters allows to draw regression lines characteristic of both deposits from various sedimentary environments and deposits from one single environment but with different histories as to their transport dynamics.
