| Tartalmi kivonat: | An overview is given in this paper by genetic types about the secondary sulphate minerals that occur in the territory of Hungary. At present we know about 60 secondary sulphate minerals from Hungary (Table 1). Numerous rarities occur among them, including bonattite, fornacite, koktaite and millosevichite. The secondary sulphate minerals of the sulphide ore deposits and ore indications are quite variegated, indicating the variety of precursor sulphide minerals. Especially variegated sulphate parageneses occur in the ore deposits of Nagybörzsöny, Recsk and Rudabánya. In magmatic and sedimentary rocks, jarosite and gypsum commonly form the weathering of disseminated pyrite and/or marcasite grains. Bauxite deposits are particularly enriched in iron-sulphates. Secondary sulphates can be found in large amounts in all coal beds and especially on the burning dumps. The important occurrences are Tokod, Egercsehi and Miskolc-Lyukóbánya. A species-rich sulphate paragenesis is known from Lesenceistvánd, where it formed by the weathering of the marcasite that impregnates the sandstone. |
