INDIANAPOLIS Native American use of galena at Kincaid Mounds, a settlement occupied during the Mississippian period (1150 to 1450 CE), resulted in more than metric tons of lead pollution ...
Fluorite (fluorspar), sphalerite (zinc ore), and galena (lead ore) were mined from major mineral deposits in heavily faulted Mississippian rocks in Hardin and Pope Counties, southernmost Illinois, from the early 1800s until the last mine closed in 1995. Mining ceased because of cheaper sources from other countries, primarily China and Mexico.
Common salt is procured by evaporating the water of salt springs. The lead mines in the vicinity of Galena are very extensive, and of great value to the state. The mineral has been found in every portion of a tract for more than 50 miles in extent. The ore lies in beds, or horizontal strata, varying in thickness from one inch to several feet.

Sparkly prospecting sample of galena from the undeveloped VMS (Volcanic Massive Sulphide) Izok Lake deposit, Nunavut Territory, Canada. Fistsized chunk was collected from the 'Discovery Boulder' on an island in Izok Lake. This boulder was reduced into souvenirs over time. It was part of a boulder train which led to geophysical surveys and discovery of the deposit by diamond drilling beneath ...
Artifacts also found in these graves include large white chert blades, cubic galena (lead ore) crystals, copper artifacts (usually beads and awls), ground stone artifacts (stone tube pipes, birdstones, gorgets), and necklaces made of shell beads traded from Native groups in marine environments.
LEAD AND ZINC PRODUCTION. Deposits of galena, the lead mineral commonly associated with zinc and silver, occur in Blanco, Brewster, Burnet, Gillespie, and Hudspeth counties. Zinc comes primarily from the mineral sphalerite, or zinc sulfide. Lead and zinc occur with other minerals in .
The lead and zinc ores are associated with openings along vertical joints (crevice deposits) or with systems of inclined and horizontal fractures (pitch and flat deposits). Crevice deposits occur mainly in the Galena Dolomite; residual concentrations of galena are found at the surface in the soil above
Oct 21, 2019· Native American use of galena at Kincaid Mounds, a settlement occupied during the Mississippian period (1150 to 1450 CE), resulted in more than metric tons of lead pollution deposited in a small lake near the Ohio River. New data from IUPUI researchers found the lead did not originate from this Southern Illinois settlement but instead was brought to the site from other
The ore mined is composed of scheelite, covellite and galena with waste material consisting primarily of apatite, sericite and quartz. Documentation from 1983 describes a single ore body as having a lenticular or lens shaped form reaching 3,650 meters (11,975 feet) long, 579 meters (1,899 feet) wide, and 10 meters (32 feet) thick.
