Abstract
A chemical and mineralogical investigation of a Moroccan pyrophyllite is pr esented. X-ray powder diffraction has been largely used for phase identific ation and crystal symmetry determination. It is shown that this mineral has a triclinic symmetry with cell parameters: a = 5.160 Angstrom, b = 8.993 A ngstrom, c=9.360 Angstrom, alpha=90.77 degrees, beta=100.57 degrees, and ga mma=89.71 degrees.
