THE BÜKK AND UPPONY MOUNTAINS The Paleozoic rocks of this area consist largely of argillaceous slates, sandstones, and limestones. The limestones are, of course, calcareous, while in the argillaceous slate quarries, quartz veins are found. These contain massive calcite and some siderite, which is very much decomposed to goethite, together with tabular albite crystals and a little disseminated pyrite or chalcopyrite. In the Permian sandstone from the region of Nagyvisnyó traces of uranium mineralisation and other sulfides have been found. In argillaceous slates of the Uppony mountains small 'prospect' quarries were started unsuccessfully at the beginning of this century for iron and manganese. A phosphatic assemblage found in the argillaceous slates in the quarries and on the scree slopes between Dédestapolcsány and Nekézseny is mineralogically much more interesting. The phosphate minerals, beraunite, kingite, vashegyite, cacoxenite, and wavellite, are white and yellow, and appear in the quarries as coatings, crusts, or as very tiny crystals.
