Abstract
The precise age of the youngest part of the geosynclinal fill of the North Greenland fold belt has been the subject of important discussion, particularly with regard to the problem of dating the Palaeozoic diastrophism (Kerr, 1967; Dawes, 1971). Since Lauge Koch's field work between 1916 and 1923 it has been known that strata bearing Monograptus priodon were involved in the folding (Koch, 1920), indicating the presence of Silurian of Llandovery-Wenlock age. In addition, Poulsen (1934) identified Cyrtograptus cf. C. multiramus and Monograptus bohemicus in collections made by Koch from unfolded shales on the platform, to the south of the fold belt, which demonstrated that the section included Wenlock and early Ludlow strata.
Highlights
Locality 1, GGU Collections 82722-82731 collected by P
This assemblage is of early Ludlow age
This assembly is of Ludlow, probably early Ludlow age
Summary
Locality 1, GGU Collections 82722-82731 collected by P. The presence of abundant monograptids similar to M. transgrediens indicates a Pridoli, probably later part of Pridoli, age. A single specimen closely similar to M. aequabilis indicates an earliest Devonian age for the strata from which it was collected.
