The following petrographical descriptions of the rocks of the Complex are arranged in the order given in the preceding table. This chapter has been written entirely by Dr. Greenly. These rocks, being granitoid in texture, and having a foliation-type peculiar to themselves, are quite different in aspect from all other members of the Complex that are present in the Region.

These rocks are related to the Gardar Province, a rift zone active during the Mesoproterozoic as Palaeopangea broke apart. Rifting ceased before transition into oceanic spreading and as a result the igneous products were.

Abstract. The Ilímaussaq complex in South Greenland is a well-studied multiphase alkaline to peralkaline intrusion of MesoProterozoic age. Most of the Ilímaussaq rocks are extremely enriched in alkalis, iron, halogens, high-field-strength elements (HFSE) and other rare elements, forming one of the most differentiated peralkaline rock suites by: The Mesoproterozoic Gardar Province in South Greenland developed in a continental rift-related environment.
Several alkaline intrusions and associated dyke swarms were emplaced in Archaean and Ketilidian basement rocks during two main magmatic periods at – Ma and – by: 1. Introduction. Wegmann () adopted the term ‘Gardar Formation’ from the old Norse bishopric of Gardar in south Greenland, as the name for the distinctive association of essentially unmetamorphosed and undeformed alkaline intrusive rocks and successions of clastic sediments and subaerial lavas which are beautifully exposed in the area.

Thirty-seven volcanic units were identified, mapped, and informally named. A minimum of 1, meters of volcanic section is present. The rhyolites consist of phenocrysts of albitized alkali feldspar Cited by: 4.Geology - Geology - Petrology: Petrology is the study of rocks, and, because most rocks are composed of minerals, petrology is strongly dependent on mineralogy.
In many respects mineralogy and petrology share the same problems; for example, the physical conditions that prevail (pressure, temperature, time, and presence or absence of water) when particular minerals or mineral .
