Where to Find Feldspar in Maine

Maine feldspar is a defining mineral of the state's pegmatite belt. Mount Apatite in Auburn (Androscoggin County) yields cleavelandite (white tabular albite) alongside green and watermelon tourmaline. Mount Mica in Paris (Oxford County) produces microcline, perthite, and amazonite (the blue-green potassium feldspar) in some of the largest pegmatite pockets in North America. The Newry pegmatites add cleavelandite blocks and amazonite, and the Bumpus quarry has produced perthite up to several meters across. Most Maine feldspar is collected from quarry dumps; specimen-grade crystals come from active pocket mining and rarely surface on the open dumps.
