AMIS0304 REE Glenover Carbonatite South Africa

Origin of Material: AMIS0304 is a commissioned CRM made up of material supplied by Fer-Min-Ore (Pty) Ltd from the Glenover Phosphate Mine on the Glenover Carbonatite Complex.  This deposit is located 88km north of Thabazimbi, Limpopo Province, South Africa. The Glenover complex is an irregular pipe like carbonatite body approximately at the centre of a large biotite pyroxenite plug with cone sheets and irregular intrusions of carbonatite emanating from the pipe.  Rare Earth Elements are associated with this Carbonatite.An apatite bearing hematite breccia body, which has been exploited for its phosphate content, is situated at the centre of the biotite pyroxenite, immediately north of the central carbonatite pipe.

Mineral and Chemical Composition: The central body of the carbonatite is composed of beforsite, an ankerite rich rock with crystallographic and physical characters resembling dolomite and siderite. The pyroxenite was an earlier event and comprises mainly decomposed biotite-phlogopite. The pyroxenite has been intruded by carbonatite dykes, sills and cone sheets and, where cut by the carbonatite, it has undergone carbonatisation and is veined with beforsite and sovite.
