Comment: Gold is usually associated with Pyrite and other sulfides, and many times cannot be noticed because of the association with these resembling minerals. In certain localities, minerals that contain these sulfides are heated high enough for the sulfides to depart, enabling the Gold to remain intact on the matrix. Such Gold is known as "Roasted Gold", and is occasionally sold in "rock shops". (From http://www.minerals.net/mineral/elements/gold/gold.htm)
