He named it after the small community of Morden, Nova Scotia, Canada, along the Bay of Fundy, where it was first found.

[4][5][6] Mordenite’s molecular structure is a framework containing chains of five-membered rings of linked silicate and aluminate tetrahedra (four oxygen atoms arranged at the points of a triangular pyramid about a central silicon or aluminium atom).

Its high ratio of silicon to aluminum atoms makes it more resistant to attack by acids than most other zeolites.

Good examples have been found in Iceland, India, Italy, Oregon, Washington, and Idaho.

[6] It is also found in marine sediments, as in the Ural Mountains and in dikes where water has attacked and altered volcanic glasses, as on the Isle of Arran in Scotland.
