...There are several other polymorphic structures, including the monoclinic parawollastonite. At temperatures above 1150°C, it transforms into pseudowollastonite, which has a homogeneous heterocrystalline three-membered ring (SiO 3 ) 3 structure. It generally results from contact metamorphism by intrusive rocks in limestone, but can also result from high-grade regional metamorphism. *Some of the terminology that refers to "pseudowollastonite" is listed below.
