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

Pressure dependence of compressional-wave velocities (Vp) in tholeiitic, alkalic,
and nephelinitic basalt and in ultramafic lithologies composing upper-mantle
underpinnings of Hawaiian volcanoes. Of particular interest is nonlinear behavior

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
hand, trachytes and some phonolites may have formed by mobilization of fenites
or by ...

Diamond Deposits: Origin, Exploration, and History of Discovery
The single kimberlite (Dalbykhsky) field in this region is located south of the
Anabar shield along an east-west–trending deep-seated fault. Similar structural
locations are characteristic of Africa, where carbonatite-nephelinitic magmatic ...
