The mineral leucite is not a rock-maker of the first magnitude, but it has nevertheless attracted special interest because of its abundance where found. This latter characteristic places it in the group of feldspathoids, which in a minor way have the same important relations to the classification of igneous rocks as do the feldspars themselves.
