The ferrierite group of zeolite minerals (the FER structure) consists of three very similar species: ferrierite-Mg, ferrierite-Na, and ferrierite-K, based on the dominant cation in the A location. Zeolites (Greek zein, "to boil" lithos, "a stone" are hydrated Aluminosilicate Minerals and have a micro-porous structure A mineral is a naturally occurring substance formed through geological processes that has a characteristic chemical composition a highly ordered atomic structure and specific Magnesium (mægˈniːziəm is a Chemical element with the symbol Mg, Atomic number 12 Atomic weight 24 Sodium (ˈsoʊdiəm is an element which has the symbol Na( Latin natrium, from Arabic natrun) atomic number 11 atomic mass 22 Potassium (pəˈtæsiəm is a Chemical element. It has the symbol K (kalium from qalīy Atomic number 19 and Atomic mass 39 An ion is an Atom or Molecule which has lost or gained one or more Valence electrons giving it a positive or negative electrical charge Ferrierites are orthorhombic minerals with highly variable cationic composition, (Na,K)2Mg(Si,Al)18O36(OH)·9H2O. In Crystallography, the orthorhombic Crystal system is one of the seven Lattice Point groups Orthorhombic lattices result from stretching Calcium and other ions are often also present. They are found in vitreous to pearly, often radiating, spherical aggregates of thin blade-shaped transparent to translucent crystals.
Ferrierite typically occurs as an alteration mineral in basaltic rocks and in tuffaceous sediments. Basalt (bəˈsɔːlt ˈbeisɔːlt ˈbæsɔːlt is a common Extrusive Volcanic rock. Tuff (from the Italian "tufo" is a type of rock consisting of consolidated volcanic ash ejected from vents during a volcanic eruption In North America, it is found at Kamloops Lake, BC, Canada (the original Type locality) and Leavitt Lake, California. Kamloops Lake in British Columbia, Canada is situated on the Thompson River just west of Kamloops. Ferrierite was named for Canadian geologist and mining engineer Walter Frederick Ferrier (1865-1950). Walter Frederick Ferrier (1865 &ndash 1950 was a Canadian Geologist and Mining engineer.
Synthetic ferrierites have even greater cation variability and have important uses as commercial filters and ion-exchange beds.
