Ironsand - Wikipedia

Ironsand, also known as iron-sand or iron sand, is a type of sand with heavy concentrations of iron is typically dark grey or blackish in colour. It is composed mainly of magnetite, Fe 3 O 4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium.. Ironsand has a tendency to heat up in direct sunlight, causing temperatures high enough to cause minor burns.
