Phlogopite

Franklin Quarry, Franklin, Sussex County, New Jersey, USA
Locality type:Quarry
Classification
Species:Phlogopite
Formula:KMg3(AlSi3O10)(OH)2
Comments:Identified before the nomenclature changes by IMA mica-group subcommittee of the IMA. All known analyses show Fluorine dominant over hydroxyl. The giant phlogopites that are so famous from the Franklin Marble have been re-defined as fluorophlogopite. While actual phlogopite may occur in the marble in very small quantities, its existence remains unproven by chemical analysis.
