Hałdy po górnictwie rudnym i fosforytowym w krajobrazie Gór Świętokrzyskich

Jach Beata, Rutkiewicz Paweł

Theaimofthiswork was to present selected heaps left after late medieval and modern iron and copper ore and phosphate mining, visible in the landscape of the Holy Cross Mountains. The heaps left after underground exploitation of iron and copper ores most often take the form of small piles around a mine shaft (in. Polish warpia). The oldest, medieval heaps are smallin size. With the development of technology and the deepening of the shafts, the heaps were heaped up and became larger. Currently, most of the heaps are covered with forest, thanks to which they have retained their original shape. Some of the heaps, that are located in agricultural areas, have been obliterated or destroyed. Some heaps have been remodelled by development of housing, andothers dismatled (either completely or partially) to obtain mineral resources. A small number of heaps are located in protected reserve areas. The publication was prepared on the basis of material from the digital Heap Geodatabase (in Polish Geobaza Hałdy) (https://cbdgportal.pgi.gov.pl/haldy/).

Environmental effects of historical charcoal burning associated with water-powered ferrous metallurgy (Mała Panew basin, southern Poland)

The main aim of this study was the reconstruction of the environmental changes (identifiable at this stage of research) resulting from large-scale charcoal production for the needs of historical water-powered metallurgy in selected sites in the Mała Panew basin. The identification of the remains of charcoal hearths was carried out by analysing shaded relief models. Shaded relief models were created from data from Airborne Laser Scanning (LIDAR). In order to verify the charcoal hearth remains identified in digital images, ground proofing was carried out. The charcoal hearth remains were subjected to sampling. Fragments of charcoal were extracted from the samples, which were then sent for analysis to identify tree species. In order to determine the age of chosen charcoal hearth remains, 10 charcoal pieces were submitted for radiocarbon dating. The following taxa were identified: Scots pine (Pinus sylvestris), alder (Alnus sp.), birch (Betula sp.), oak (Quercus sp.), Norway spruce / larch (Picea abies / Larix sp.), Silver fir (cf. Abies alba) and ash (Fraxinus excelsior). The taxa identified are dominated by Scots pine (56%). This research demonstrates that valuable wood of deciduous species might have been overex-ploited at the initial stage of metallurgical production and very quickly exhausted, being replaced by fast-growing coniferous species. The excessive exploitation of the forests might have had negative environmental effects such as the transformation/modification of the species composition of the forest cover, significant deforestation of exploited areas, intensification of floods or the initiation of aeolian transport of sands. All the charcoal hearth remains investigated date to the period from 1677 to 1957 AD.
