Crustal Structure and Mineral Deposit Systems: 3D-modelling of base metal mineralization in Jameson Land (East Greenland)

Providing research and education at a high international level is a prerequisite for the raw material sector to develop competitive and cost effective exploration methods. The NordMin project CRUSDMID-3D is a consortium between research institutes, academia and SME supporting a PhD project to study some of the geological processes in Greenland that are related to ore deposits, to understand the relationships between structures and mineralization. The new geological and structural data together with aeromagnetic/electromagnetic surveys and the drill-core data added new values to the regional knowledge of East Greenland. The exploration tools developed within the PhD-project are expected to be useful in planning and executing future exploration campaigns in similar but also other geological environments.



Geological Setting

Geological investigations in the Jameson Land Basin in central East Greenland started at the end of the 19th century and subsequent exploration work was carried out by hydrocarbon and mineral exploration companies. Seismic reflection surveys were conducted in the 1980’s by Atlantic Richfield Company (ARCO) over the Jameson Land Basin. In 1997, an airborne magnetic and electromagnetic survey was conducted by the Geological Survey of Denmark and Greenland (GEUS) in the northern part of the basin. In 2012 GEUS and NERC (Natural Environment Research Council, UK) led a Lidar, Hyperspectral and aerial photos survey over the eastern part of the basin. This enabled the production of a high resolution Digital Elevation Model and of a photogrammetric model for 3D-Photomapping. Field investigations in 2011 and 2012 in the Klitdal area (eastern part of the Jameson Land basin) encouraged the exploration company Avannaa Resources in 2013 to form a joint venture with Anglo American to drill in the Klitdal area the sedimentary-hosted base-metals sequence.
