Structural evolution of the Ikerasak area, Umanak district, central West Greenland

Abstract

The 1980 season was the last of the three seasons allocated for the mapping of the 1:100000 sheet 70 V. 2 Nord-Agpat (for background and references see Pulvertaft, 1979). The most important area that remained to be mapped in 1980 consisted of the islands Ikerasak and Talerua, which were known from the 1965 reconnaissance by T. C. R. Pulvertaft to have a structural style somewhat different from that of the northern part of the sheet area where low dips are prevalent. The author was invited to join the team of geologists from Copenhagen University responsibie for the Agpat sheet to map these islands and the mainland peninsula of Akuliaruserssuaq to the south-east (fig. 11).
