The AA. investigate the slagheaps of the industrial plants of Salgótarján which have been polluting for dozen of years. Investigating the grain size distribution and the chemical composition of slag, the AA. identified the mineral assemblage

The study was executed on 6 barren conical spoil heaps, which are excellent study objects to bring the slope aspect in relation with rill erosion. Three indicators for rill erosion (volume of rills, drainage density and mean distance of the head cut
of the 5 uppermost rills till the top of the spoil heap) were associated with 4 explanatory factors (slope gradient, vegetation density, rock fragment cover and slope aspect). It is shown that the rill volumes on windward slopes are 3 times higher than

Rapid formation of rock varnish and other rock coatings on slag deposits near Fontana, California
Manganiferous rock varnish, silica glaze and iron skins have formed on 20- to 40-year-old slag piles near Fontana, southern California. Rapid rock-varnish formation is associated with an unidentified cocci bacterium that grows rapidly in culturing
experiments, combined with the likelihood that Mn-rich solutions flow over slag surfaces. A new model is proposed for the formation of silica glaze, involving soluble Al-Si complexes and the nature of wetting films. Iron skins occur where runoff
At the request of local authorities, we have determined a method of quantitative evaluation of the ecological and aesthetical value of the pit heaps. The diversity and the rarity of species and plant communities, the maturity of the latter
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.
