Opis:
The paper concerns the Liban quarry in Cracow, which is located in the Podgórze district of Cracow. It shows the outline of the geological structure and history of quarrying, while the current topography and dominant elements of the relief of this object are discussed in more detail. Anthropogenic changes in the natural environment of the quarry have revealed its geodiversity and enhanced its biodiversity. It contains vertical rocky walls, debris cones, waste-heaps, a vast undulated surface of the quarry bottom, as well as diverse flora and fauna. Within the borders of the Liban quarry, the remains of industrial buildings and the staging for the film entitled "Schindler's List” have survived. Despite the fact that the extraction has already finished a long time ago, the quarry has not been systematically reclaimed or developed.

Opis:
In NW Spain, on the border of Galicia, Asturias and Castile and Leon, in the Rio Sil River, the exploitation of gold placer deposits tooks place. Gold from alluvium was exploited by the Celts, but the Romans developed large-scale exploitation. The paper describes the attractive landscape, which is a relict ofa Roman gold mine. This mine was probably the largest in the Roman Empire. Gold occurs in the Neogene alluvium (~20 Ma years). The deposit is probably a weathering product of gold-bearing quartz veins. Three deposit series have been distinguished. They are composed of conglomerates with intercalations of finer-grained material - sand and clay. The top series, Las Medulas, has the thickness of >100 m, the middle series, Santalla, has the thickness of 0-30 m, and the most gold-bearing (20-100 mg/m3, at the base even 60-300 mg/m3) and intensely red gangue Orellan series found at the base is 0-25 m thick. The basement is represented by Devonian and Silurian limestones, shales and quartzites, Ordovician limestones, dolomites and shales, and Cambrian quartzites with slates at the top. The deposit is cut by numerous faults, which form blocks, and are the cause of variations in the level of the deposit series. The mining technique used by the Romans is also characterized. In the mine, where mining works were carried out on the surface of1228 ha, about 1626 tons of gold were exploited during the periodfrom ~25 BC to the early third century AD,. A technique ofruina montium was usedfor gold exploitation. It consists of drilling in excavations ofpoorly compacted rocks - tunnels, adits, shafts (up to a depth of 100 m). Through these excavations, the waterfallingfrom above was transferred. Water under pressure has burst and washed out the deposit. Presently, the remains of the Las Medulas deposit series are represented by the characteristic red rocks, which are poorly compacted. They create morphology of the mining landscape, which is inscribed on the UNESCO World Heritage Site list.

Opis:
The open-pit excavation of minerals results mainly in landscape transformation. In consequence, a new anthropogenic landscape form occursarises, and its dimensions are increasing with the progress of excavation – at certain point, the resulting terrain changes become irreversible. The quarry, left abandonedafter the mining process, can be filled with water and, thus, forms a water reservoir. This paper is focused on the analysis of a number of reservoirs which were established in closed gravel and limestone quarries in the area of Kraków. They were located in highly industrialized or environmentally valuable terrains. As time elapsed, both types became attractive leisure sites for nearby residents due to the natural succession of plants and high water quality. The complete usage of their values, through implementation of adequate rehabilitation and adaptation measures, would allow them to be sterling areas fulfilling certain functions, which constitute these reservoirs’considerable attractiveness and harmonious composition in the landscape.
