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 Przedbórz region in the Przedborska Upland (central Poland) is characterized by an above-average presence of erratic boulders. They have never been the subject of separate studies before. The aim of this article is to indicate their large population in central Poland and to characterize the traces of the impact of various morphogenetic processes on their current size and shape. The authors indicate the Scandinavian source areas of some of the studied erratic boulders. The article also highlights the scientific, educational, social and aesthetic function of erratic boulders, which should be used when planning the sustainable development of the region. In peripheral tourist areas, geotourism is an effective tool for economic growth. The erratic boulders discussed in the article, which are unique objects of natural heritage, have great potential to revive this branch of nature tourism.

We describe the penultimate glacial – last interglacial transition from the one of the numerous palaeolake successions in central Poland, which have yielded many documented Eemian and Early Weichselian floral records. In the new profile, Parchliny 2016, the lacustrine deposits were analysed lithologically, botanically, zoologically, and geochemically, providing new data that illustrate the environmental transition from the Late Saalian (MIS 6a) to the Eemian interglacial (MIS 5e). Five phases of palaeolake development have been distinguished. The first phase was related to the rapid melting of a dead ice block buried in the tills to form a lake. The second phase documented a Late Saalian initial succession, with the dominance of open steppe communities (Stadial 1), followed by a third phase with gradual increasing density of vegetation, the spread of boreal forests (Zeifen interstadial) and further increase in open communities and the retreat of pine (Kattegat stadial). The fourth phase reflected the beginning of Eemian interglacial by the expansion of pioneering birch-pine and purely birch forests and an increasing proportion of deciduous trees, including oak (Vth phase). Diatom, cladoceran and geochemical studies indicate at least two stages of lake development. The first stage (Late Saalian) was of an open lake (2–4 m deep), in relatively cold conditions and nutrient-poor water with the lowest amounts of organic carbon and nitrogen. The second stage (Eemian interglacial), shows warmer, shallower conditions in which the lake’s primary production increased, the water was well oxygenated, and there were more trophic levels.

The article presents results of research of three sections (Kuców 9, 10 and 16). Two of them record fluvial and lacustrine interglacial sediments and the third, cold-stage glaciolacustrine sediments. They were formed inside the Miocene–Pliocene syncline depressions in a central part of the southern horst within the Kleszczów Graben. Fluvial and lacustrine deposits of the Middle Pleistocene Interglacial (Mazovian or Ferdynandovian in the Czyżów Formation) are described from the Kuców 9 and 10 sections. Their sediments are located in marginal parts of a buried river valley and within an oxbow palaeolake, then covered by glaciofluvial deposits of the Ławki (Early Saalian) and Rogowiec (Late Saalian) Formations. The Kuców 16 section comprises ice-dam sandy lithofacies (Kuców Formation, Elsterian) of a marginal part in a proglacial lake. Two pollen diagrams of K65/15 and Kuców 9 sections represent the Mazovian (Holsteinian) succession, although in the Kuców 9 section some features are typical for the Ferdinandovian succession.

This article presents the achievements of the employees of the Holy Cross Mts. Branch of the Polish Geological Institute in the field of applied geology: geological cartography, geology of natural resources and hydrogeology. The area of the Holy Cross Mts. is located in central Poland and for hundreds of years was the main source of metal ores and rock raw materials for the Polish state. Investigating the possibility of using these minerals and raw materials in the modern economy was the reason for establishing the Polish Geological Institute in Kielce. Shortly before World War II, a department of the Institute was established in Kielce for a detailed geological study of this interesting area, where the full profile of the Phanerozoic deposits is present, from the oldest Cambrian to Quaternary. The basic work performed by geologists in Kielce was the preparation of geological maps. During the 80 years of the Institute's activity in Kielce, geological maps on various scales were made, ranging from 1:300,000 to 1:50,000. Currently, detailed mapping at the 1:50,000 and 1: 25,000 scales are being prepared. The search for deposits of iron, copper and other metals, conducted by the Kielce Institute, did not lead unfortunately to discovery of economically useful deposits. On the other hand, large deposits of rock building materials have been identified and documented and are currently exploited mainly for road construction. The region of the Holy Cross Mountains and their vicinity is unique in comparison to other regions of Poland because the entire population and economy are supplied with water from underground sources. Taking care of resources and adequate water quality is the main goal of the hydrogeologists employed at the Holy Cross department of the Polish Geological Institute. They organized and supervise a network that controls the water level and its quality, the impact of quarry activities on the groundwater levels, and prepare various types of hydrogeological maps.

Kielce is a city situated in the centre of the Holy Cross Mountains, one of the most interesting geological areas in Europe. For this reason, institutions related to mining and geology have been operating here for over 200years. After the establishment of the Polish Geological Institute in 1919 in Warsaw, one of its founders, Jan Czarnocki, took steps to establish a regional branch of the Institute in Kielce, whose aim was to conduct scientific and exploratory research in the Holy Cross Mountains area. These activities were successfully completed in 1937, and since then, with a short break due to the Second World War, a branch of the Polish Geological Institute has been operating in Kielce. Since 1961, its headquarters have been located in a modern building, designed entirely for its needs, which has recently been modernized and expanded. Several dozen people employed in the Holy Cross Branch of the PGI-NRI carry out tasks in the field of applied geology and scientific research, focused on the study of an almost complete succession of Phanerozoic rocks in this region - from the Cambrian the history of the Holy Cross Branch of the PGI-NRI, and to present the most important to the Quaternary. The aim of this article is to provide a brief introduction to data related to the research and accomplishments of the geologists working in Kielce.
