Oct 21, 2019· "We knew that Mississippians used this lead mineral called galena, which is a silvery mineral that they would crush to essentially create ancient glitter, but
Galena forms isometric crystals in which the ionic lattice is like that of sodium chloride. The mineral is easily weathered to secondary lead minerals, the upper part of galena deposits often containing cerussite, anglesite, and pyromorphite.

Galena is the most common mineral containing lead, and has been well-known throughout the centuries. It is often well crystallized and forms in many interesting and distinct crystal shapes. Some cubic crystals have their edges cut by the partial octahedral growth, some octahedral crystals have their points flattened by cubic growth, and many
Oct 21, 2019· Researchers believe the lead pollution in Avery Lake is the result of galena powder blowing or being washed into the lake as the people living at Kincaid Mounds crushed and used the mineral. "Lake cores are a natural archive of human utilization of the landscape, and in this case, the human inputs into those lakes," Wilson said.

Galena Galena (PbS) typically forms within hydrothermal veins in igneous and metamorphic rocks. Its silvery metallic luster, cubic crystals, and high density make Galena easy to identify. Minerals which contain enough metal to extract easily are called ore minerals, and Galena (lead sulfide) has been a primary ore of lead since ancient times.. Due to its relatively low melting point, Galena
