Amblygonite, LiAlPO 4 F in combination with quartz goes through an OH-F exchange to make montebrasite, LiAlPO 4 { F, OH } at temperatures greater than 480 �C . Due to its formation caused by the amblygonite-montebrasite alteration and the presence of tourmaline in the environment where brazilianite forms, different elements are present in the mineral such as P, Al, Fe, Mn, Ba, Sr, Ca, Mg, Na, K, F, and Cl.
