Thomsonite is a common zeolite, forming series, with the mineral species being named Thomsonite-Ca and Thomsonite-Sr. Thomsonite-Ca, by far the more common of the two. Found within fractures in igneous rocks, typically basalts as well as in contact metamorphosed rocks, alkalic igneous rocks, subvolcanic rocks, and occasionally as a cement on sandstones. Thomsonite is pyroelectric, meaning it can generate a charge temporarily when heated.
