Igneous rock rich in feldspathoid minerals

Foidolite (sodalitolite variety) from Namibia

Thin section of foidolite under polarizing microscope. In the foreground there is a large yellow sodium pyroxene grain surrounded by fine grains.

Foidolite (/ˈfɔɪdəlaɪt/) is a rarephaneritic (coarse-grained)intrusive igneous rock in which more than 60% (by volume) of light-coloured minerals arefeldspathoids.^[1] Crystals ofalkali feldspar,plagioclase,biotite,amphibole,pyroxene, and/orolivine may be present within the rock. Thevolcanic equivalents are termedfoidite andphonolitic or tephritic foidites.

Some foidolites are a potential source ofaluminium.
