Melilitite
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.

Classification of Melilitite

Modal classification of volcanic rock containing melilite, after Streckeisen, 1978)
Sub-divisions of Melilitite
Mineralogy of Melilitite
Essential minerals - these are minerals that are required within the classification of this rock:
Melilite | Ca2(Al,Mg,Fe)((Al,Si,B)SiO7) |
Non-essential minerals - these minerals are common, sometimes major components, but are not always present:
Olivine | Equivalent to Fayalite-Forsterite Series; usually a more or less Fe-bearing forsterite. |
Pyroxene | A petrological term for Pyroxene Group. |
