Surface investigations in the coal-bearing sediments of Disko and Nugssuaq are used for an outline of the geological framework and for reserve estimates of 20-30 million tons. Some of the technical properties of West Greenland coals are evaluated on the basis of laboratory investigations of selected seams. Dominating maceral .is vitrinite. Rank is in the high volatile bituminous A range with minimum ash percentages around 5 per cent. Coking properties are poor. Ashes have fusion temperatures from 1450°C upwards.
