Pseudowollastonite is a high-temperature mineral phase of CaSiO3 and is polymorphous with wollastonite. Its formula can alternatively be written as Ca3Si3O9. Other names include ß-Wollastonite, and cyclowollastonite.Pseudo wollastonite on Mindat.orgGlossary of Geology, eds. Julia A. Jackson, James P. Mehl, and Klaus K. E. Neuendorf; American Geosciences Institute, 2011, 5th ed., p. 524
It occurs in high temperature (pyrometamorphic) environments such as the Hatrurim Formation of the Negev Desert and the graphite mine at Pfaffenrenth near Hauzenberg, Bavaria.Fleischer, M., 1973, New mineral names: Cyclowollastonite, American Mineralogist: 58: 560 It also occurs in slags and cement.
