O těžbě bauxitu v Maďarsku

V základní škole jsme se často učili, že hliníkárna ve Žiaru nad Hronom zpracovává maďarskou surovinu. Málokdo však věděl, kde se jedno z nejvýznamnějších evropských ložisek bauxitu přesně nachází.

Near the village of Gant, in Hungary, is located one of the world's largest reserves of readily accessible bauxite. The deposits, discovered in 1915, have only recently been extensively exploited. Present workings consist of two open pits, in each of which a remarkably continuous layer of bauxite ranges from 15 metres to 30 metres in thickness. The bauxite, thought to be of Lower Cretaceous age, overlies an uneven surface of Triassic dolomite, and is in turn overlain in part by Tertiary strata, in part merely by unconsolidated materials. Associated faults have been important in localizing areas preserved from recent erosion.
