The Geochemical Survey Program aims to conduct a general geochemical survey of the regional areas to create a geochemical atlas of Saudi Arabia. The program includes the collection of valley sediments and the determination of their chemical contents, about 60 elements, and the generation of databases and geochemical maps that can be used in mineral exploration, land use planning, and environmental assessment. In mineral exploration, geochemical reconnaissance surveys aid in providing preliminary information on areas with high concentrations of certain elements, which indicate the presence of ores of gold, copper, zinc, lead, nickel, and REEs. The database and geochemical maps will also provide preliminary information in planning the establishments or expansions of cities, villages, and agricultural areas by identifying the distribution areas and extents of some environmentally relevant elements, such as arsenic, mercury, lead, radioactive elements, and other toxic elements that can be harmful to the ecosystem and human health.
