Description:	The paper describes the physical and cristallographic chacteristics of diaspore that occurs in the Quadrilatero Ferrifero, Brazil. With this purpose it presents a brief comment on the occurences, mineral assemblage and geologic features of some deposits of diaspore found in the world. Thirteen phase equilibrium reactions are presented and discussed on the basic of T, P, SiO2 dependence and uH2O.
