Clintonite
Formula: Ca(Mg,Al)3(Al3SiO10)(OH)2
Description: Clintonite is an enigmatic entry for this locality. It was "not observed" by Dunn (1995), but was reported in an article published in 1957 and 1958 that was a Ph. D. thesis by Henri Struwe, originally at Leiden University, The Netherlands (Data on the Mineralogy and Petrology of the Dolomite-Bearing Northern Contact Zone of the Querigut Granite: French Pyrenees by Struwe, Henri). The specimen was reported as from "Franklin". Confirmation of the specimen's identification seems valid, but where in the Franklin Marble it was actually found is unknown. The referenced specimen was located in The Netherlands, but while it was in dolomite, it did not contain clintonite, but did contain phlogopite in a fine-grained pulverant mixture. The Franklin Marble does extend into New York state and Amity is the type locality for clintonite, but it is uncertain if the identified specimen is even from New Jersey.
