Wollastonite - Wikipedia

Wollastonite is a calcium inosilie mineral (Ca Si O 3) that may contain small amounts of iron, magnesium, and manganese substituting for calcium. It is usually white. It forms when impure limestone or dolomite is subjected to high temperature and pressure, which sometimes occurs in the presence of silica-bearing fluids as in skarns [5] or in contact with metamorphic rocks .
