Igneous and Metamorphic Petrology
Carbonatite contains >50% carbonate minerals, usually calcite. Since 1960 the
nephelinitic Oldoinyo Lengai volcano in Tanzania has erupted alkali carbonate
lavas and pyroclastics. Earlier arguments whether carbonatite is truly a magmatic

Geology of the Eastern Rift System of Africa
Basanites, tephrites, most of the phonolites, and all the feldspar-free volcanics
are considered to be derivatives of nephelinitic parental magma. 0n the other

The single kimberlite (Dalbykhsky) field in this region is located south of the
