Name:For Scottish mineral collector James Edington (1787-1844).


Zeolite Group. Edingtonite Subgroup.

Most edingtonites are orthorhombic (space group P212121), while some are tetragonal (space group P-421m) and called 'tetraedingtonite'. Orthorhombic edingtonites have (Si,Al) order, while tetragonal edingtonites are characterised by (Si,Al) disorder (symmetry increase due to disorder).

Classification of Edingtonite
