Abstract

A chemical and mineralogical investigation of a Moroccan pyrophyllite is presented. X-ray powder diffraction has been largely used for phase identification and crystal symmetry determination. It is shown that this mineral has a triclinic symmetry with cell parameters: a=5.160 Å, b=8.993 Å, c=9.360 Å, α=90.77°, β=100.57°, and γ=89.71°.
