Overview
Dachiardite-K is a rare zeolite-group mineral with the formula K4(Si20Al4O48)•13H2O. It is the potassium-analogue of dachiardite-Ca and dachiardite-Na, as suggested by the suffix "-K". Dachiardite honors Italian geologist and mineralogist Antonio D'Achiardi. In 1906, his son and mineralogist Giovanni D'Achiardi described and named the mineral dachiardite after he discovered it in a granitic pegmatite.
