Abstract
The discovery in 1982 of scheelite in stream sediments in the Godthåb area and in situ mineralisations in the early Archaean Akilia rocks on Storø in Godthåbsfjord (Appel, 1983) was followed up by field work in the summer of 1983. The regional stream sediment sampling programme was extended to Ameralik fjord, south af Godthåb, and to the inner parts of Godthåbsfjord. Field work at night with ultra-violet light examination was carried out on Storø and Sadelø in Godthåbsfjord and in Kobbefjord, south of Godthåb. The latter part of the programme was carried out with the assistance of volunteers from Ungdomstjenesten (Greenland's Youth Organisation). The folIowing report is based on field observations only. Laboratory work has been Iimited to X-ray identification of scheelite in four rock samples; two from Storø, one from Sadelø and one from Kobbefjord.

The discovery in 1982 of scheelite in stream sediments in the Godthåb area and in situ mineralisations in the early Archaean Akilia rocks on Storø in Godthåbsfjord (Appel, 1983) was followed up by field work in the summer of 1983
The supracrustal rocks ean be traced from the inner part of Godthåbsfjord to the Buksefjorden area, south of Godthåb, and they can probably be correlated with the supracrustal rocks of the Fiskenæsset area 150 km south of Godthåb
The youngest major event in the Godthåb area is the formation of the Qorqut granite
Summary
The discovery in 1982 of scheelite in stream sediments in the Godthåb area and in situ mineralisations in the early Archaean Akilia rocks on Storø in Godthåbsfjord (Appel, 1983) was followed up by field work in the summer of 1983. In these gneisses remnants of a supracrustal belt occur, the so-called Akilia enclaves. It was in some of the layered amphibolites in the Akilia enclaves that scheelite mineralisations were discovered (Appel, 1983). Sediment samples were collected in all major streams in the Ameralik fjord area south of Godthåb, in the ioner part of the Godthåbsfjord and in the Isukasia area.
