Tridymite
or quartz paramorph on trydimite
Hexagonal XX on trachytic matrix, up to 0.6cm, reddish for iron
oxides coating. The specimen is
covered by green coating of celadonite that sometimes cover also
the tridymite XX, as you can see in the 2nd photo. Some analysis seem to
demonstrate that specimens from this locality are quartz
paramorph on trydimite (quartz often replaces tridymite)
