Geological Information Sodalite is a member of the feldspathoid group of minerals and typically forms in igneous rocks that are low in silica, such as nepheline syenites and related rocks.
In Tamil Nadu, sodalite is found in small quantities within certain igneous rock formations. These deposits are usually associated with alkaline rock complexes, which are rich in sodium and poor in silica.
