| Tartalmi kivonat: | The authors of the scientific'report "Comparative study of rare alkali elements (Li, Rb, Cs) distribution in magmatic, metamorphic, and volcano-sedimentary formations in Hungary" (Kubovics et a). 1992a) prepared within the framework of NSRF (OTKA) No. 728/87 intended to answer the questions raised for more than 40 years ago by SZADECZKY-KARDOSS (1955). _ The rare alkali element contents of geological formations in Hungary were systematically studied. It has been established that the highest Li-concentrations in Hungary are linked to lithiophorites found in bauxites and Mn-ores. The differentiation products of the granites in the Velence Mts namely aplites and orthoclase from pegmatitic nests are most enriched in Rb. The enrichments of Cs in various rock types - independently of their origin, e.g. in lamprophyres, basalts, andesites, rhyolites, and their pyroclastics - proved to be the result of postmagmatic alteration that resulted in zeolitisation which is the principal host of Cs. |
