Galena is the largest city in and the county seat of Jo Daviess County, Illinois, with a population of 3,429 at the 2010 census. A 581-acre (235 ha) section of the city is listed on the National Register of Historic Places as the Galena Historic District.The city is named for the mineral galena, which was in the ore that formed the basis for the region's early mining economy.

Galena has a metallic luster and is gray in color. Its most outstanding feature is its high density; a sample of galena is much heavier than other minerals of the same size. Galena is a lead ore. Galena also has three directions of cleavage at right angles to each other; it breaks into shiny metallic-looking cubes.

What is Galena? Galena is a lead sulfide mineral with a chemical composition of PbS. It is the world's primary ore of lead and is mined from a large number of deposits in many countries. It is found in igneous and metamorphic rocks in medium- to low-temperature hydrothermal veins. In sedimentary rocks it occurs as veins, breccia cements, isolated grains, and as replacements of limestone and ...

Galena and chalcopyrite were selected as objects of study. Perfect cubic cleavage ({100}) of galena made it possible to carry out AFM measurements on natural surfaces of the mineral containing products of secondary transformations and on its fresh chips.

Galena Group. Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.
