Celadonite -family mica in pyroclastic rocks from Hrvatsko zagorje (Croatia)

Diagenetically zeolitized pyroclastic rocks which crop out in NW part of Hrvatsko zagorje are often green due to the presence of celadon green mineral which is concentrated in the fiamme. In thin sections one can see that the mineral occurs in thin veins and inside pumice vesicles.
