Wollastonite
Wollastonite as a most important of these minerals occurs only in a handful of places where it is abundant enough to make mining worthwhile. One of them is Willsboro in New York State (two photos below). It forms when limestone reacts with silicate fluids: CaCO 3 (calcite) + SiO 2 (quartz) → CaSiO 3 (wollastonite) + CO 2 (carbon dioxide)
