Map the regional scale spatial distribution of heavymineral sand deposits in the coastal plain of the southeastern us the spatial distribution is important because it along with many other factors affects whether mining is feasible and it provides a regionalscale context for smallscale sitespecific studies

Today most zircon is produced from mining sediments from beach or alluvial deposits zircon is often a coproduct at mining or processing operations where ilmenite and rutile are being mined for their titanium content zircon is extracted by dry mining methods if the deposit is shallow or contains harder materials

The main exposure risks are associated with industrial inhalation and dermal exposure because of the low solubility of zirconium and hafnium ecological health concerns in the aquatic environment and in soils are minimal heavymineralsand mining may lead to increased erosion rates when the mining is managed improperly
