Thorium Minerals - There are many Thorium minerals.
Thorium is three times more abundant than Tin in the Earth's crust and is about as common as Lead. Thorium has one of the largest liquid temperature ranges of any element, with 2946 °C between the melting point and boiling point. Thorium is slightly radioactive (half-life equals the age of the universe) and may one day replace Uranium in nuclear reactors as a safer alternative.
Thorium is a component of the magnesium alloy series, called Mag-Thor, used in aircraft engines and rockets
