Many books have been written about Missouri Geology in the 300 years since the first European saw the glint of galena (lead sulfide) and mistook it for silver. One website can hardly claim to outdo literally thousands of pounds of paper which add up to our sum of knowledge on the subject.
Galena Galena is among one of the most popular minerals for anyone to have. The name galena comes from the Latin word "galena" which means lead ore. The color of this mineral is dark gray to silver. Galena streaks dark gray, almost the color of pencil lead. On the Mohs hardness scale, galena is a 2.5 and has a specific gravity of 7.4 to 7.6. Galena is found in cavity fillings of limestone. In 1941 Missouri produced over $15,000,000 of the lead in the world. It came from Flat River, Fredericktown, Joplin and central Missouri (Keller).
