Intrusions and Magmatic Complexes in Greenland
This dataset describes the intrusions and magmatic complexes of Greenland, forming a dedicated information layer within the GEUS GMOMDB2 database, displayed via the Greenland Mineral Occurrence Map (GMOM2). It includes 194 registered intrusions and complexes grouped into 23 magmatic provinces. The data are compiled from GEUS geological maps, published sources, and company reports.
The Palaeogene intrusions and complexes of East Greenland (66–75°N) are related to the opening of the North Atlantic and the influence of the ancestral Icelandic mantle plume. The magmatic evolution includes flood basalts, dyke swarms, and intrusive activity from 61 to 13 Ma.
Economic mineralisation is documented in several complexes, including the Skaergaard palladium deposit and the Malmbjerg porphyry molybdenum deposit, representing classic examples of rift- and post-rift-related mineral systems.
The dataset provides harmonised, quality-controlled geological information to support exploration and research activities in Greenland.

- Beskrivelse
-
The data were compiled by the Geological Survey of Denmark and Greenland (GEUS) during the GMOMDB2 upgrade. Information originates from GEUS databases, geological maps, published studies, and exploration reports. Each entry includes location, lithology, age, type, and references.
Data management follows the GeoSciML model and GEUS data quality principles.
Quality assurance includes:
- Controlled vocabulary and data model conformity.
- Role-based data management and approval workflows.
- Public access limited to released, non-confidential records.
- Continuous updates as new data become available.
