Formula:
(Ca,Fe,Y,Th)(Nb,Ti,Ta,Zr)O

System:Orthorhombic
A variety of Zirconolite

Described as a new mineral by Berzelius (1824) from Stavern, Vestfold, Norway. Later shown to be identical with Zirconolite described in 1956. In spite of its priority and widely use in the literature polymignite is now considered a metamict variety of zirconolite.
