The Upper Aravalli Group consists 13 of greywacke-slate-phyllite, quartzite, dolomite and silty arenite (host for sulphides of zinc and lead) while carbonaceous and pelitic phyllites, dolomite, quartzite, stromatolite, phosphorite, chlorite schist, amphibolite, quartz arenite and local conglomerate belong to Lower Aravalli Group.

NOTES ON SOME ABANDONED COPPER, LEAD, AND ZINC MINES IN THE PIEDMONT OF IA James L. Poole INTRODUCTION The Piedmont province of ia is bordered on the east by unconsolidated and semiconsolidated sedi- ments of the Coastal Plain and on the west by mainly igneous and metamorphic rocks of the Blue Ridge province.
The gently-dipping Devonian dolomite beds south of Great Slave lake in northern Canada are nearly everywhere concealed by a cover of glacial drift and muskeg. Nevertheless, in 1898 or earlier, four small outcropping areas of dolomite, richly mineralized with lead and zinc sulphides, were discovered.

Dolomite in Arkansas Associated with Lead and Zinc. Pink dolomite is widespread in certain Paleozoic dolostone formations in north Arkansas. Many of the abandoned lead and zinc mines in the Ozark Plateaus have pink sparry dolomite as the first or early mineralization which preceded the sphalerite, galena, and chalcopyrite deposition.

Dolomite may form as a hydrothermal replacement mineral and, as such, is especially abundant as a gangue mineral in the ore deposits of the Upper Mississippi Valley zinc-lead district in southwestern Wisconsin. Ferroan dolomite appears in several of the state's Precambrian iron formations. Finally, dolomite locally occurs in the state in marbles.

Dolomite serves as the host rock for many lead, zinc, and copper deposits. These deposits form when hot, acidic hydrothermal solutions move upward from depth through a fracture system that encounters a dolomitic rock unit. These solutions react with the dolomite, which causes a drop in pH that triggers the precipitation of metals from solution.

Lead-zinc mines and prospects in the Municipio de Januaria, in. northern Minas Gerais, Brazil, are scattered along both sides of the Eio SSo Francisco for more than 100 kilometers. Seven deposits of lead and zinc and one fluorite prospect are grouped in a small area from 10 to 15 kilometers west of the village of Itacarambi.

Dolomite can also serve as a host rock for lead, zinc, and copper deposits. In the chemical industry, dolomite is used as a source of magnesia (MgO). The steel industry uses dolomite as a sintering agent in processing iron ore and as a flux in the production of steel.
Galena has been produced from the Upper Mississippi Valley zinc-lead district in Wisconsin since the seventeenth century. Some mines started by Native Americans may predate this. Major lead mining occurred from the 1800's until the late 1970's. A few small lead …

Dolomite is used as an ornamental stone, a concrete aggregate, and a source of magnesium oxide, as well as in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper.
Mar 26, 2018· Dolomite crystals are usually white or greyish pink in colour, yet the presence of certain impurities can bring a colour change; i.e. Iron in dolomite gives it a yellowish brown tint. Furthermore, metals such as Lead and Zinc can substitute magnesium in the mineral structure.
Calcium in calcite is replaced by magnesium forming the mineral dolomite. This reaction usually destroys fossils in the limestone and forms holes in the rocks, which are then good places where lead-zinc minerals may form. Brines flowing through other sediments such as shale may pick up lead and zinc …
Copper, lead, and zinc deposits have been found in the Cambrian Shady Dolomite and the Ordovician Beekmantown Formation in the Valley and Ridge Province. The most important deposit of the zinc-lead ores within the Shady Dolomite is the Austinville-Ivanhoe group of ore bodies in Wythe County.

Mississippi Valley-Type Deposits Mississippi Valley-type deposits, commonly referred to as MVTs, are hydrothermal lead-zinc ore depos-its that are characterized by (1) low-temperature forma-tion (50°-200''C, but usually 100°-150°C), (2 ...
Polymetallic vein and replacement deposits are characterized by elevated abundances of Pb-Zn±Cu±Au±Ag±Mo±As ± Bi±Sb. In some districts, ore proximal to igneous intrusions is copper and gold rich, and grades laterally (and sometimes vertically) into lead-zinc-silver-rich ore. A distal, manganese-enriched zone is present in some districts.
