Datolite is a hydrous
calcium boron silicate often associated with zeolites in basalt.
The datolite from northern Michigan occurs as cryptocrystalline fillings within gas
bubble holes in
basalt (amygdules). The most common color of the Michigan
datolites is white but they be colored
various shades of grayish pink by
inclusions
of microscopic-sized flakes of native copper.
