Ironsand - Wikipedia

Ironsand, also known as iron-sand or iron sand, is a type of sand with heavy concentrations of iron.It 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.

Black Sand | Exploratorium Museum Exhibits

Not usually magnetic in and of itself, black sand can and will become magnetized in the presence of another magnet. As each tiny grain of magnetized black sand becomes a (temporary) magnet itself, the magnetic field in that spot gets amplified, and more black sand gets attracted—ultimately creating the porcupine-like spikes that you see here.
