Galena, Illinois called Galena "La Pointe" and early Americans adopted this name as "The Point". Early documentation officially records the name as "Fever River", an early name for the Galena River, though it does not appear that this name was commonly used. George Davenport, a retired colonel in the United States Army, successfully shipped Galena's first boatload of lead ore down the Mississippi River in 1816. Three years later, Jesse W. Shull built a trading post. The Thomas H. January family, who arrived in 1821 from Maysville, Kentucky, are considered the first permanent American settlers. The next year, the US Department of
Ore genesis classified hydrothermal deposits as "hypothermal", "mesothermal", "epithermal", and "telethermal". Epithermal deposits are hydrothermal ore deposits formed at low temperatures (50-200 °C) near the Earth´s surface (<1500 m), that fill veins, breccias, and stockworks. The age of formation of epithermal deposits in México is currently being investigated. "As they require the conjunction of specific environmental conditions to form, particular mineral deposit types tend to occupy specific geodynamic niches," therefore, this page has been organised by metal commodity. It is also possible to organise theories the other way, namely according to geological criteria of formation. Often ores of the same metal can
