Lead is a naturally occurring metallic element usually associated with other ore minerals (primarily those of zinc, silver and copper) such as pyrite, sphalerite, quartz and barite.Trace amounts of other elements including gold are sometimes found with lead ore. The most common ore mineral of lead mined in the United States is galena with the chemical symbol PbS.

Some Galena may contain up to 1% silver in place of lead. The large volume of Galena that is processed for lead produces enough Silver as a by product to make Galena the leading ore of Silver. To quote Allen N Wollscheidt, Galena, back 75 years ago, was the stuff -- the crystal -- of crystal radio sets.

The Viburnum Trend of southeast Missouri is one of the world's largest producers of lead. The lead occurs as galena, predominantly in two crystallographic forms, octahedrons and cubes. Many studies have shown that octahedral galena is paragentically early, the more abundant of the two crystal forms, and is commonly modified in the cube. Those studies also have shown that the cubic form is
