✦ Synopsis
Carbonatites in Southern
Malawi belong to the late stage intrusion of the Chilwa Alkaline Province of Upper Jurassic to Lower Cretaceous. They are characterised by a circular zone of fenitised rocks in which carbonate rocks, ijolites and alkaline rocks derived from nephelinitic lavas intruded forming igneous ring complex structures. Major Economic minerals, which are found in the carbonatites, are rare earth minerals, apatite and pyrochlore.
