Meionite derived its name from the Greek word for "less", referring to its less acute pyramidal form compared with Vesuvianite.
Meionite comes from the mineral group Scapolite.
Meionite forms a series with Marialite.
Mizzonite is an intermediate between Meionite and Marialite.
Meionite mainly occurs in metamorphosed rocks, some pegmatites, ejected volcanic blocks and altered mafic igneous rocks.
