American Museum of Natural History Visit: Part 7 - Franklin NJ Minerals

Franklin, New Jersey, is an old mining district that lies about 40 miles northwest of Manhattan. Its fame lies in its rich deposits of zinc, exploited through the 1950's. The Franklin Mine is world-famous for being the most proficient source of fluorescent minerals, and is known as the fluorescent capital of the world. It also has produced over 300 known minerals, one of the largest mineral counts for a single locality. Nearby, in the borough of Ogdensburg, is a continuation of the same ore vein, with the same assemblage of minerals. Both Franklin and Ogdensburg have produced very important mineral specimens, with old classics such as Rhodonite and Willemite within the cases of museums throughout the world. The American Museum of Natural History is no exception, having a special affinity to these locations due to their proximity.

Presented below are some of the minerals on display from Franklin and Ogdensburg, New Jersey. This post concludes our museum report on the American Museum of Natural History. However, visit our Instagram page for additional photos not included on these pages.
