Abstract
South-east Renland occupies an internal position in the Caledonian orogenic belt of East Greenland. The area comprises migmatised paragneisses ofCaledonian supracrustal origin intruded by concordant sheets of garnetiferous augen granite in the west. The gneisses and granites are folded in large-scale, tight to isoc1inal folds. Intermediate igneous rocks with charnockitic affinity were intruded after the folding. The principal intrusion is an extensive, concordant sheet delimiting an area of gneisses in the east that have undergone further migmatisation and granite intrusion. Prominent among the many fractures are normal faults with downthrow to the east. No indications of economic mineralisation were observed.
Highlights
This report describes the geology of about 900 km2 in· '; south-east Renland that was mapped at a scale of l :50.000 during six weeks of inclement weather in the summer of 1969
South-east Renland lies within the internal part of the Scoresby Sund fjord complex and centres on 26° 15' W and 71 ° 8' N
Access is on foot using the large valley glaciers in the interior, by boat along the precipitous cliffs of the shoreline of 0fjord, or by helicopter where topography is most severe
