Biermann (Bethel) quarries, Bethel, Fairfield Co., Connecticut, USA
Two quarries in a granite pegmatite now well-known for its bertrandite crystals. Most references describe or list minerals but provide little history. Todd (1906) visited the "recently opened" quarry and reported that "This vein, we learned, is controlled jointly by the New Jersey Flint and Spar Company and the International Pottery, both of Trenton, New Jersey, and all its stone is shipped there." He mentions an immense tourmaline crystal measuring 3 feet by 18 inches which had been taken from the workings. The quarry apparently was not active during WWII because it does not appear in Cameron et al's (1954) Pegmatite Investigations 1942-45 New England. It may have been worked for beryl in the 1950s. It is now located in Huntington State Park, so collecting is not allowed. Some references such as Schooner (1961) refer to this quarry incorrectly as the Codfish Hill Quarry, though the minerals he describes are correct for Biermann.
The nearby tourmaline-rich ledge is 100 meters or so away and is not related to the pegmatite. The host rock is a chlorite rich schist. The tourmaline species mostly listed is dravite though some claim it is schorl.
