Pyrophyllite Wikipedia

Pyrophyllite occurs in phyllite and schistose rocks, often associated with kyanite, of which it is an alteration product. It also occurs as hydrothermal deposits. Typical associated minerals include: kyanite, andalusite, topaz, mica and quartz. Deposits containing well-crystallized material are found in: • Manuels, Newfoundland and Labrador, Canada, talc-like bright white appearance, high grade, no impu

Pyrophyllite an overview ScienceDirect Topics

Pyrophyllite (Al4 Si 8 O 20 (OH) 4) is the end member of dioctahedral 2:1 clay minerals containing no isomorphic substitution and therefore no layer charge. All tetrahedral sites are filled with Si 4 +, two-thirds of the octahedral sites are filled with Al 3 +, and the remaining one-third of the sites is vacant.

Pyrophyllite, Al 2 [Si 4 O 10 ] (OH) 2, is the simplest structural prototype for 2:1 dioctahedral phyllosilicates. Since it does not possess permanent structural charge as other clay minerals do, it is used to investigate sorption properties of the clay surfaces not related to the permanent structural charge.
