Data on the dickite occurrence of Mád (Hungary)
The rhyolite tuffs of the Sarmatian age in the surroundings of Mád were kaolinized on the action of hydrothermal fluids. The smaller and larger hollows of the porous tuff is filled out with dickite and kaolinite. The dickite could be identified by DTA as well as X-ray pattern. Dickite appears as 15—...

| Tartalmi kivonat: | The rhyolite tuffs of the Sarmatian age in the surroundings of Mád were kaolinized on the action of hydrothermal fluids. The smaller and larger hollows of the porous tuff is filled out with dickite and kaolinite. The dickite could be identified by DTA as well as X-ray pattern. Dickite appears as 15—20 l1 long and 3—8 wide crystals and the kaolinite always in dense aggregations of micron sized .granules. The fact that it is associated with kaolinite shows that special conditions are necessary for it to form, these are, however, still fairly unexplored. |
