Keweenaw Peninsula, Michigan
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.
