Abstract
The work was focussed to the position-origin and petrology of the rhyolite in the Rudabánya Mts. Our basic intention aimed to make exact determinations of the feldspars; their structure and chemical composition by electron microscope as well as electron microprobe analyses. According to these results the original rock-forming feldspars were sanidines and the minor plagioclase have been transformed to albite, by the effect of secondary sodium-metasomatism. Besides this transformation the rhyolite suffered silicification and carbonatisation. The relation and position of the Jurassic black shale and the intercalated rhyolite blocks, have also been analysed in detail. The methods were the following: trace element geochemistry (B, Li), vitrinite reflectance and macro- and microscopic analysis. All these data show, that the not completely cooled rhyolite entered to the unconsolidated Middle Jurassic sediments, so its age is probably the same or perhaps a little younger than that of these sediments.
