  • Quarries in landscape and geotourism
  • Geotourism ; Landscape ; Poland ; Post-industrialization ; Quarry
  • Once its mineral working operations cease, a quarry begins functioning in harmony with the landscape as a former mineral working site. That is when the biotic and abiotic elements arrive at a state of equilibrium. The scenic function of a quarry
  • should be interpreted as a set of elements, composed of escarpments, cliffs, spoil heaps, the state of exploitation. The paper discusses the impact of quarries on the landscape and their potential value for geotourism.
  • Quarries and wildlife conservation in the Yorkshire Wolds, England
  • Disused quarries can often provide important wildlife habitats in the British Isles. Plant species lists and quadrat data from an ecological survey of 30 disused quarries and pits were used to look at the plant communities present and species-area
  • Landform replication experiments on quarried limestone rock slopes in the English Peak District
  • Applied geomorphology ; Carbonate rock ; England ; Human impact ; Karst ; Limestone ; Quarry ; Restaurant trade ; Slope ; Slope dynamics ; United Kingdom
  • This paper describes the land surface changes resulting from limestone quarrying and considers the nature of landform evolution on quarried limestone rock slopes. This is followed by a description of a new technique known as restoration blasting

  • in Britain. Quarrying may also impact on karst water resources, particularly where excavation takes place beneath the water table, but these impacts tend to be site specific whilst te geomorphological impacts are more general.

  • The Marbles sensu stricto of the Mt. Altissimo region form an important district in the central Apuane Alps and were exploited in many quarries active up to some decades ago. The marble varieties are characterized by high quality physical-mechanical
  • properties often joined with very appreciated ornamental features. At present only two large quarries are active. The most important is the Cervaiole quarry, from which decorative arabesque marbles are extracted ; the La buca quarry has been reactivated a few
  • The faunal remains from Evron Quarry in relation to other Lower Paleolithic hominid site in the southern Levant
  • The mammalian assemblage and archaeological finds from the Lower Paleolothic hominid site of Evron Quarry, situated on the northern coastal plain of Israel, are described and discussed. The mammalian faunule from Evron comprises a biogeographical

  • on the discursive formulations of the quarry in the expert language, as well as in the arguments of both local proponents and opponents of the quarries, shows the importance of ontological categories in environmental siting disputes.

  • Nonassociation of Paleoindians with AMS-dated Late Pleistocene mammals from the Dutchess Quarry Caves, New York
  • This paper reports AMS C 14 ages of 10 bones and teeth of 3 species of large mammals from the Dutchess Quarry Caves, New York. Together with the Holocene conventional C 14 dates of charcoal and the varied stratigraphic proveniences of the fluted
  • points and the dated bones, the new AMS C 14 dates argue that most strata at the Dutchess Quarry Caves contain a mixture of late Pleistocene and Holocene materials. This mixing probably resulted from post-depositional bioturbation (by humans, rodents
  • Penecontemporary tectonic forms in basement areas : evidence derived from quarry exposures on northwestern Eyre Peninsula, South Australia
  • Australia ; Fracture ; Granite ; Neotectonics ; Quarry ; South Australia ; Weathering
  • Monitoring of quarry exposures on northwestern Eyre Peninsula has shown that the granite domes of that region are structurally complex features, commonly with several structural domes within each topographic form. The rock masses are in horizontal
  • The role of roadcuts, quarries, and other artificial exposures in geomorphology education
  • Geological structure ; Geomorphology ; Micromorphology ; Quarry ; Road ; Slope dynamics ; Slope profile ; Soil erosion ; Teaching of geography ; Weathering
  • Yet, roadcuts and quarries offer much potential for learning about basic landform features, forms, and processes. This paper, with illustrated examples, discusses 5 general characteristics present in artificial exposures, that offer opportunities

  • The Wachau-Danube Valley represents a transverse valley, intersecting the Variscian Bohemian Massif. The exceptional cultural position of the region generated an increasing demand for building materials. Over the centuries quarrying had a sizeable
  • impact on slope morphology. Interdependences between quarrying and construction caused unstable rock slopes and 4 rock-mass falls have occurred at 2 quarries near Spitz (1961, 1984, 2002) and Dürnstein (2009). Rock mechanical analysis at these quarries

  • In Carrara marble basins, the long and intensive quarrying activities have produced extensive dump deposits, locally known as ravaneti. The morphological and sedimentological analyses of depositional lobes resulted in a classification of 3 types

  • Human activiy has affected the landscapes of karstic areas of the British Isles since the Mesolithic. Six main categories of human impact on limestone areas are considered in detail: ground-subsidence related; water related; quarrying; surface stone

  • Wisconsinan inter-lobal stratigraphy in three quarries near Woodstock, Ontario
  • Restoring earth surface processes through landform design. A 13-year monitoring of a geomorphic reclamation model for quarries on slopes
  • This paper discusses the reclamation problems of contour mining and quarries on slopes, where steep gradients are prone to both mass movement and water erosion. To address these problems simultaneously, a geomorphic model for reclaiming surface
  • mined slopes is described. Called the ‘highwall–trench–concave slope’ model, it was first applied in the 1995 reclamation of a quarry on a slope (La Revilla) in Segovia province (Central Spain). Results and discussion.
  • quartzite beds of the Mount Watson Formation maintain a near constant dip. They map the occurrence of 3 glacial erosional landforms : cliffs showing evidence of quarrying, scoured surfaces polished by abrasion, and overdeepenings. Cliffs and overdeepenings
  • as joints, dictates the geometry of quarried blocks and influences the spatial patterns of process dominance. Where bedding dips up-basin, the geometry of pre-existing weaknesses favours quarrying creating both cliffs and overdeepenings. In contrast, where
  • bedding dips down-basin, block geometry does not favour the creation of overdeepenings via quarrying and exposed bedding planes are subjected to glacial abrasion, producing scoured surfaces.
