Scolecite is a member of the zeolite group, and is closely related to Natrolite and Mesolite. It forms a series with those two minerals, and is the calcium-rich end member. Chemical analysis or optical tests may be required to distinguish Scolecite from Natrolite, and a single crystal may even contain part of each mineral within different zones of the same crystal.
Scolecite can be very brittle, so care should be exercised when handling specimens. Scolecite is named after the Greek term "skolec", which means "worm", alluding to its worm-like reaction to a blowpipe test.
