Vote for your favorite mineral in #MinCup26! - Sphalerite vs. Anorthite
Both zinc ore Sphalerite and calcium plagioclase feldspar Anorthite have perfect cleavage that will split cleanly if you hit them with a hammer, but only one can claim a larger split of your votes!

Metamorphic deposits - Ammonoosuc formation amphibolites with quartz veins carrying other minerals. (Note: These sites, small ledge sites where rockhounds have collected epidote crystals, etc., are near the Franconia Iron mine, but not considered a part of the mining complex. They are located higher up on the hill. Epidote crystals can also be found in the dumps of the various Franconia Iron mine workings.)
