Discuss the sources and formation of Late Paleozoic minerals. How are these resources used? What will be an ideal response?
Late Paleozoic mineral resources include bituminous and anthracite coal, petroleum,
evaporites, limestone, and quartz sand. Coal deposits formed in abundant swamps during the
Carboniferous and Permian. Petroleum resources were also formed in basins like the
Michigan Basin. Evaporite deposits include gypsum for sheetrock and limestone for cement.
Evaporites are common in arid environements An example of evaporite is the Zechstein
evaporites of Europe. Metallic resources, such as tin, copper, gold, and silver, form during
deformation of mountain building. Much of Quartz sand comes from east of the Mississippi
as fluvial deposits, and is important for the production of glass.
