The mineral newberyite Mg(PO3OH)·3H2O is a mineral that has been found in caves such as the Skipton Lava Tubes (SW of Ballarat, Victoria, Australia), Moorba Cave, (Jurien Bay, Western Australia) and in the Petrogale Cave (Madura, Eucla, Western Australia). Since these minerals contain water, the minerals lend themselves to thermal analysis. The mineral newberyite is found to decompose at 145 °C with a water loss of 31.96%, a result which is very close to the theoretical value. The result shows that the mineral is not stable in caves where the temperature exceeds this value. The implication of this result rests with the removal of kidney stones, which have the same composition as newberyite. Point heating focussing on the kidney stone results in the destruction of the kidney stone.
