The Rock Garden, established in 2019, is a geological showcase of both the Institute of Geography and Environmental Sciences of Jan Kochanowski University in Kielce and the entire Kielce region in central Poland. The collection includes specimens of about 50 rocks: those whose outcrops are located in the Holy Cross Mountains region and those brought here from Scandinavia by the ice sheet around 180 to 130 thousand years ago. The Rock Garden is of scientific importance and plays a didactic, conservational, educational, cultural, aesthetic, recreational, and geotouristic role. This article highlights its importance in the development of urban geotourism.

AbstractThe occurrence of end moraines reflects the dynamics of an ice sheet, and their inner structure is determined by processes taking place in marginal zones. In the southern part of the Kłodawa Upland of Central Poland, such moraines were formed, but opinions conflict as to their origin, including the influence of local transgression of the ice sheet, as well as its areal and frontal recession. The primary aim of this article is to analyse the inner structure of forms to define the dynamic state of the Warta Stadial ice sheet of the Odra Glaciation (Saalian). The conducted research includes fieldwork at four key sites, where lithofacial analysis was performed, as well as a geomorphological and geological mapping that included two cross-sections in greater detail. In exposures, the work focused on deformed structures of sediments. Description of key sites was extended by the creation and the analysis of general geological cross-sections. Considering the results of the research, the Kutno end moraines should not be classified as push moraines – they were revealed to be accumulative in character.

A palynological study of the uppermost Famennian section from Kowala Quarry (Holy Cross Mountains, central Poland) allowed recognition of two miospore zones: LV (Retispora lepidophyta–Apiculiretusispora verrucosa) and LN (Retispora lepidophyta–Verrucosisporites nitidus). Based on palynology and sedimentology, the black shale within the upper part of the section is identified as equivalent to the Hangenberg Black Shale, which is known globally. This black shale contains compounds characteristic of photic zone euxinia, including isorenieratane and its derivatives. Such compounds are absent in the organic-poor marls and shales occurring below the LN Zone, and are present only as traces in the layers just above the black shale, indicating fluctuations in the oxygen minimum zone during uppermost Famennian sedimentation. Palynofacies show high amounts of amorphous organic matter and prasinophyte concentrations in the black shale, and a subsequent significant decrease of amorphous organic matter concomitant with a rapid increase of terrestrial input (mainly miospores with common tetrads) in the layers above the black shale. This supports the relatively rapid change in the taxonomic composition of phytoplankton caused by fluctuations of the chemocline. The whole succession corresponds to one sea-level rise and fall. The presence of high concentrations of peri-condensed polycyclic aromatic hydrocarbons and large amounts of small charcoal particles at the Hangenberg event horizon indicate the occurrence of wildfires. Such observations suggest that atmospheric O22 levels had exceeded the critical threshold of 13 %, above which wildfires may occur, by latest Famennian time.
