The white micas of Martwy Kamie have revealedlow amounts of most of trace elements, probably due to hydrothermal processes. Enrichment in F, Rb and Csas well as depletion of Ti, Zn and Cd seem to confirm low-temperature genesis of the white micas. %K Muscovite %K greisen %K post-magmatic genesis %K hydrothermal processes %K the Izera Upland %U http://www.ptmin.agh.edu.pl/vol35no1/vol35no1_06.pdf
