Greenland 3D-Geology Legend

This report describes the different legends that can be used in order to construct an accurate, multi-scalar geo-spatial model covering Greenland: GL3D. The geological complexity, the time span covered by the outcropping rocks together with the presence of the Greenland Ice Sheet that covers almost 80% of the largest island of the Earth with more than 400 000 Km² of ice free area, put many challenges in the development of a 3D-Geological modelling.

This report will briefly introduce the geology of Greenland and off-shore, together with four levels of geological details available with particular emphasis on the development of a pilot study using the geological map 1:100 000 scale covering part of East Greenland in the Jameson Land area. Available digital maps of Greenland are in the scales of 1: 5 000 000, 1:2 500 000, 1:500 000 and partly 1: 100 000.
