It belongs to the monoclinic Crystal system and the mineral class is phyllosilicate (often categorised under silicates).
It forms in hydrothermal veins from low temperature alteration of aluminous minerals like feldspars, and as an authentic mineral in sedimentary deposits including sandstones,mudstones and shales.
Dickite is a soft mineral measuring 2.0-2.5 on the MOHs scale.
