THE GALENA GROUP OF MINERALS

The Galena Group is composed of minerals with a similar isometric structure and related chemistry. It is named for its most common member, galena. The general formula for this group is simply AX and is similar to the structure of halite. The A can be either lead, magnesium, bismuth, calcium, iron, manganese, palladium, platinum or antimony. The X can be either sulfur, selenium and/or tellurium. Only galena is common with most other members being very rare.
