Features of the Tertiary volcanic rocks of the Niaqornat area, Nûgssuaq

Abstract

During the summer of 1974 and in previous years the writer mapped parts of the volcanic sequence around Niaqornat on the north coast of Nûgssuaq. The results of the regional mapping by the writer and others have been published in the Agatdal map sheet (The Geological Survey of Greenland, 1974). Certain hitherto undescribed large-scale features of the vo1canic rocks are described here.
