Add to ORKGHydrothermal veins composed mainly of quartz, calcite and black tourmaline of the schorl-dravite solid solution series were found in the iron-ore deposits of the Lahn-Dill type near Dzbel, Jesenec and Ponikev in the Konice-Mladeč belt. The genesis of the veins seems to be connected with hydrothermal processes that are believed to be responsible for both hydrothermal alterations of basic volcanites and the formation of iron-ore accumulations
