| Associated minerals include pyrophyllite, lazulite, quartz, various brightly colored iron oxides, barite, and a suite of microcrystalline phosphates. |
| In many cases, quartz overgrowths were preferentially corroded and dissolved in the presence of pyrophyllite, most likely during acidic metasomatism. |
| Rutile crystals, commonly associated with lazulite, pyrophyllite, and kyanite, are found at Horrsjoberg, Sweden. |
| The wall rock was highly altered and consisted of a groundmass of pyrophyllite and fine-grained pyrite. |
| Pyrophyllite, a hydrous aluminum silicate, is the basis for the new product, called Airblock. |
| Groups in this class include micas, kaolins, vermiculites, chlorites, talc, pyrophyllite, and smectites. |
