Melilitite
A rock classification type
This page is currently not sponsored. Click here to sponsor this page.
An ultramafic volcanic rock consisting essentially of melilite and pyroxene; perovskite is also commonly present.
Now defined as a general term for volcanic rocks in the melilite-bearing rocks classification or chemically in field F of the TAS classification as a rock which does not contain kalsilite but has normative cs (larnite) > 10% and K2O < Na2O.
If modal olivine > 10% the rock should be called an olivine melilitite.
