Abstract
Fig. 1. Geological map of the Skjoldungen region, South-East Greenland, showing locations of samples (blue circles) selected for zircon U-Pb geochronology and zircon Hf isotope analysis. We report new zircon U-Pb and Hf isotopic data from the Skjoldungen region between c. 62°30 ́ and 63°40 ́N in SouthEast Greenland. The work was carried out under the SouthEast Greenland Mineral Endowment Task (SEGMENT); a joint project between the Geological Survey of Denmark and Greenland (GEUS) and the Ministry of Mineral Resources (MMR) in Greenland to assess the mineral endowment and update the geological knowledge of the region using modern petrological, geochemical and geochronological tools. This paper presents new zircon U-Pb and Hf isotopic data from a range of different Archaean rocks in the Skjoldungen region, which greatly improve the understanding of the history of crustal growth.
期刊介绍：
GEUS Bulletin publishes geoscience research papers, monographs and map descriptions with a focus on Denmark, Greenland and the wider North Atlantic and Arctic region. We welcome submissions that fit this remit. Specifically, we publish:
1.Short articles intended as rapid communications that are of immediate interest to the international geoscience community (these include new research, datasets, methods or reviews)
2.Regular-length articles that document new research or a review of a topic of interest
3.Monographs (single volume works, by arrangement with the editorial office)
4.Maps and descriptive texts (produced by GEUS for Greenland and Denmark, by arrangement with the editorial office)
GEUS Bulletin serves a broad geoscientific readership from research, industry, government agencies, NGOs and special interest groups.
