Abstract
Multi-modal photogrammetry has been applied in a study of the lateral continuity of lithofacies in a dark grey shale unit on the North-East coast of Disko. The shale is c. 60 m thick and can be traced laterally for 12 kilometres. It is demonstrated that it distinct sand-streaked shale facies as well as contrasting thin pale sand units can be mapped confidently and that very accurate sections can be measured when the photogrammetric conditions are optimal.

The present study, which is still preliminary in character, has shown that multi-model photogrammetry is an attractive approach to the study of thicker shale units
As boundaries and marker horizons are mapped photogrammetrically, the field work can be concentrated to the best outcrops which show those details that are beyond the resolution of the photographs
