A search was conducted for a collection of fossils found in the Pepper Mountains, in 1891, by G. Gürich (Geologisches Institut, Breslau). It was found that such a collection did exist and was probably destroyed at the end of World War II. Among other finds at the resources of the University of Wrocław was a collection of Cambrian trilobites from the Holy Cross Mts. (central Poland) with original metrics, sent in 1932 by J. Czarnocki. Parts of other pre-war collections of Cambrian trilobites from the Barrandian area and Lusatia were also found.

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.

The Chęiny-Kielce Geological Landscape Park was proposed to be created in 1991, in order to protect the geological heritage of supra regional value, as well for educational purposes and development of geotourism. It was established in 1996 as the Chęciny-Kielce Landscape Park (ChKLP). The key adjective (Geological) was missing from its name due to the lack of relevant legislation (despite this, the ChKLP was promoted as a geological park, i.a., during the International ProGEO workshops in 1997 and 2003). At the beginning of 21st century, when a Global Geoparks Network was being organized, the ChKLP, as meeting all UNESCO geopark requirements, was proposed to be included in the network. The Geopark Kielce Centre (an institution previously established for geoheritage promotion purposes) was crucial in the foundation of the new geopark (on the basis on ChKLP), and preparing an application according to UNESCO instructions. The Chęciny-Kielce Geopark, eventually called Holy Cross Mountains Geopark (as its area was extended) was established and included in the Global Geoparks Network in 2021. It should be emphasized that the Polish Geological Institute also played a key role in the whole process, because both innovative ideas (the geological landscape park and the centre of geological education) originated in its Holy Cross Mts. Branch.

The Holy Cross Mts. and their vicinities is a unique area on the geological map of Europe since rocks of all Phanerozoic systems, including the Cambrian to Quaternary, are exposed there. The variable rock types provide great cognitive and educational opportunities, but also stimulate the exploitation of various types of minerals. On the one hand, mining activities contributed to the recognition and better exposure of rocks, but on the other hand, they often threaten the natural environment and become burdensome for the inhabitants. The study of the balance between environmental protection and human mining activity is carried out by environmental geology, which is an important part of the activity in the Holy Cross Mts. Branch of the Polish Geological Institute (PGI), where various tasks in this field have been carried out for over half a century. The care for protection and promotion of the geological heritage of the Holy Cross Mts has been an important task of geologists working in the Kielce Branch of the PGI throughout its over 80-year history. It is manifested in the legal protection of the most interesting geological areas and geosites, and the promotion of geological knowledge in wide public opinion. The geological education in the Holy Cross Mts. plays a special role because the inanimate nature is a very valuable element of natural environment that distinguishes the Kielce region from other regions of Poland.

The southern slope of Łysica Mountain, which is the highest elevation of the Holy Cross Mountains, is comprised of three lithological complexes divided by parallel fault zones. The uppermost part of the succession consists of quartzitic sandstone of the Wiśniówka Formation. The formation is underlain by a complex of sandstone with mudstone interbeds, with black claystone underneath, which is exposed in the upper part of the Glęboczka ravine succession. The strata of the first and the third complexes dip northward, whereas those of the second complex dip southward. In the fault-bound zone between the second and the third complexes, there are concentrations of weathering iron ore. The black claystone, which is lithologically similar to this of the Pepper Mountains Formation, contains a taxonomically rich assemblage of organic-walled microfossils (acritarchs) diagnostic of the Upper Cambrian (Lower Furongian) successions. The new record of microfossils allows determining the age of the succession composing the Łysogóry Mountains for the first time in the history of regional geological investigation.
