Brunswick pegmatite field. Granite pegmatite

Critical Area Status:

The Standpipe Hill Quarries proper are inventoried by the USA Critical Mineral Areas program and designated as an Important Site needing protection from development. The reason is that the locality has produced world-record length bismuthinite crystals (to 45 cm) and is the only habitat in Maine where several mineral species occur. GPS co-ordinates designate the site of concern. There are several relatively small pegmatites nearby that have produced excellent magnetite crystals or in other, very fine monazite-(Ce) crystals, but are not requiring protection. The nearby Yedlin Locality is of international significance and needs preservation and access.
