Geological Guide - South Greenland. The Narsarsuaq - Narsaq - Qaqortoq region. This book is a handy guide book to the fascinating geology of South Greenland which houses some world-famous mineral localities. It focuses on the description of the main geological features of the region and of localities and is planned as a handy guide book to be used in the field.

The Ilimaussaq intrusion belongs to the late Precambrian Gardar province, south Greenland (Upton, ; Emeleus and Upton, ).

Abstract. The Ilimaussaq alkaline intrusion in South Greenland provides examples of various types of igneous layering. Inch-scale layering occurs in the least differentiated rocks augite syenite and pulaskite and is probably caused by a nucleation-diffusion mechanism.

The Ilímaussaq intrusion consists of an augite syenite shell and a central cumulitic series of layered peralkaline (agpaitic) nepheline syenites with both roof and bottom cumulates.

Microprobe analyses of the strongly zoned mafics show that the pyroxenes range from ferro-salite through hedenbergite to aegirine, the amphiboles from hastingsite. On beryllite and bertrandite from the Ilímaussaq alkaline intrusion, South Greenland: Responsibility: by Haldis Bollingberg and Ole V.

Ilimaussaq intrusive complex The Ilímaussaq complex (Fig.1) is one of several alkaline complexes formed during Mesoproterozoic rifting in the southwestern part of Greenland, which collectively is called the Gardar province.

The Ilímaussaq Intrusive Complex is part of the Gardar Province in South Greenland (Emeleus & Upton, ), which is interpreted to be a failed rift (Upton & Emeleus, ). It consists of 10 major intrusions that range from alkali granite to nepheline syenite and (rare) carbonatite, along with hundreds of gabbroic to trachytic or phonolitic.
