Exhibit Gold in conglomerate Since their discovery in 1886, the Witwatersrand deposits have yielded more than 40,000 tons of gold. Exhibit Coal Coal is the most abundant fossil fuel. It forms when dead and decaying plants are buried in swamps and marshes. Exhibit Salt Salt beds form in sedimentary basins where water collects and evaporates. Exhibit What is an ore? Ore is defined as an economic concentration of minerals. The richness of ores can be vastly different.
