Provenance of heavy minerals in beach sands,

Abstract The sands in the fore- and backshore zones between Rio Grande and Chui (Rio Grande do Sul State, Brazil) are predominantly composed of quartz, but in some places heavy-mineral concentrations appear as dark patches on the surface of the backshore. Opaques (ilmenite, magnetite, leucoxene, limonite) are the predominant minerals. The predominant transparent species are epidote, augite

Mapping Heavy Metal Concentrations in Beach Sands

It is necessary to investigate the contamination of beach sands to ensure water safety, as they may contain potentially toxic trace elements. Tourists, oil spills, or replenishing sands can cause beach sand contamination. In this study, heavy metal contamination maps of lead (Pb) and zinc (Zn) were created for Wolpo Beach, on the eastern coast of Korea, using portable X-ray fluorescence and
