Python Island, in the northern part of Lake Chilwa, contains a vent filled with blocks of gneiss and small areas of breccia consisting of angular fragments of slightly fenitized granulite and syenitic gneiss in a sparse comminuted matrix containing siderite and goethite. Florencite has been identified. Garson (1965a) classified this as a ‘carbonatite and agglomerate vent’.
