Kalsilite is a very rare mineral, and its presence is sufficiently important to merit defining rocks with notable kalsilite as a separate group. In the present scheme a threshold value of 10% modal kalsilite has been adopted, the same as the threshold for melilitic rock and leucitic rock. Kalsilite behaves metastably and only rarely survives slow cooling, so virtually all rocks containing kalsilite are fine- or very fine-grained lavas. Coarse-grained rocks containing kalsilite (e.g. kalsilite-bearing syenite and kalsilite-bearing-biotite pyroxenite) have been reported from Russia; however they are extremely rare.
