Mineralpedia Details for Pectolite
Named for the Greek word pektos, meaning “compact,” in reference to its resistance to being crushed. Pectolite is a widespread mineral with many localities including in Italy, Germany, Scotland, Russia, the United States, Canada, India, Morocco, and South Africa, to name just a few. Pectolite occurs in nepheline syenite, as a hydrothermal mineral in basalts and diabases, in serpentinites, peridotites and calcium-rich rocks. Pectolite can be triboluminescent, produces light when broken.
