Magnetite Iron from South-West Utah: These Ultramafics (extremely concentrated in Iron) have the Fe3+ isotope for magnetic attraction. High specific heat and heat capacity allow these stones to absorb large quantities of heat, and they require about 50,000 degrees Fahrenheit to turn into a gas. Ultramafics come from deep within the Earth's crust, correlating with extreme density and the ability to hold immense amounts of heat in both solid and liquid phases.
Ultramafics often form from Hotspot locations deep inside the Earth, similar to Basalts, arching from near the core all the way to the surface. These stones can travel long distances due to their high heat capacity, remaining in a buoyant phase until they cool off. They are often the result of a balance between radioactive decay and fusion in stars, making them excellent for heating a home, bed, or thermal-mass stove.
