Abstract
A survey of uranium, thorium and niobium mineralization in the Illmaussaq alkaline intrusion which was started in 1964 was extended in 1965 to include a survey of beryllium mineralisation. This was continued during 1966.
Highlights
The Illmaussaq complex is an intrusion dominantly built up of an early augite syenite followed by nepheline syenites
The beryllium minerals are generally found in late hydrothermal veins consisting of albite, analcime, natrolite and ussingite, but are found disseminated in the naujaite especially where it is albitized
Most of the veins are found in the naujaites, but some are found in the coarse-grained lujavrites on the Kvanefjeld plateau
Summary
The Illmaussaq complex is an intrusion dominantly built up of an early augite syenite followed by nepheline syenites (an agpaitic suite consisting mainly of naujaites, kakortokites and lujavrites). REPORT ON THE SURVEY OF BERYLLIUM, NIOBIUM, URANIUM AND THORIUM MINERALIZATION IN THE ILIMAUSSAQ COMPLEX, SOUTH GREENLAND A survey of uranium, thorium and niobium mineralization in the Illmaussaq alkaline intrusion which was started in 1964 was extended in 1965 to include a survey of beryllium mineralization. The beryllium minerals are generally found in late hydrothermal veins consisting of albite, analcime , natrolite and ussingite, but are found disseminated in the naujaite especially where it is albitized.
