1 ELDSPAR AND EPHELINE YENITE By Michael J Potter Domestic survey data and tables were prep ared by Raymond I Eldridge III statis tical assistant and the world production table was prepared by Ronald L Hatch lead international data coordinator Fe. S feldspar production in 2010 was valued at about 36 million The three leading producers accounted for about 88 of the production with four other companies supplying the remainder Producing states were North Carolina Virginia California Ida ho Oklaho in .

This is why a mafic name prefix is often used, for example hypersthene andesite.
