Online data on the geology and mineral resources of Greenland
The Government of Greenland and GEUS collectively administrate the Greenland Mineral Resources Portal
, which provides access to a wealth of information about geology and mineral resources in Greenland. During the year, the portal was developed further and new topics and features were introduced. The portal provides access to different scale geological maps, geophysical and geochemical data, aerial photos, field observation data and information about geological environments. Searches for data are done via an interactive GIS map, and users can also access publicly available reports made by companies, GEUS publications, mineral deposit descriptions and analyses of samples from the popular mineral resources hunt, Ujarassiorit, in Greenland. The portal gives access to searches in several underlying databases and users can study search results via metadata and PDF files. Much of the data can be downloaded via the webshop linked to the portal.
During the year, GEUS also launched a data portal on ruby occurrences in West Greenland. This portal provides information about 87 ruby-sapphirine occurrences in the area around Qeqertarsuatsiaat south of Nuuk, as well as eight occurrences near Nuuk and Maniitsoq. These data include descriptions of the geology and mineralogy of the occurrences, geological locations as well as references to geological maps, scientific publications, journals and reports.
3D seismic data available via online shop for the oil industry
In 2015, GEUS expanded access to data in the FRISBEE online shop where users can search for and buy data on oil and gas exploration and other surveys in the deep subsurface in Denmark. The database contains reports, logs, merged logs and digital core photographs from deep boreholes released in Denmark. The data available are primarily from the Danish sector of the North Sea, however there are also data from onshore drilling operations and drilling operations in Danish coastal waters. Via FRISBEE, users can search for data and pay for data via credit card or invoice. FRISBEE now also contains reports and data from publicly available 3D seismic surveys. Most of these data are from the North Sea, however there are also data sets from 3D seismic surveys on land, e.g. at Stenlille on Sjælland and at Feldsted and Tønder in Sønderjylland. The data available in FRISBEE are data from original 3D processing and only end products are available in the database, e.g. 'final migration' and/or 'final stack'.
New book on geological exploration in Greenland
In 2005 GEUS published the book entitled: Grønlands geologi udforskes - glimt af geologernes arbejde (Exploring the geology of Greenland - glimpses of the geologists' work). This book recounts how geologists worked on their many expeditions to all parts of Greenland over the course of almost 70 summers. For many years, geologists have been trudging the mountains, traversed the country by aeroplane and sailed the coastline of Greenland in order to map the geology. This book tells the story of their work and provides glimpses into how they lived, what they ate, and what ships, aeroplanes and helicopters they used to cross this vast country with its harsh nature. The book is aimed at readers with an interest in Greenland, geological exploration, expeditions and adventure. It focuses on the state's exploration activities. Since 1946, these activities have been carried out under the auspices of GEUS, involving many Danish and foreign researchers. The richly photo-illustrated book contains fact boxes on the geologists' work during their expeditions to all parts of Greenland and it contains over 70 profile descriptions of geologists and other explorers in Greenland. The author, Niels Henriksen, worked at GEUS from 1963 to 2000, and, in his capacity as head of department, he lead geological mappping for many years. He took part in exploration from early on as a student and has participated in field work in Greenland for 35 summers, and many of these expeditions are described in the book.
Common European minerals databases
In recent years, GEUS has participated in several EU-funded research projects to promote the exchange of geodata across European borders. These projects support the EU INSPIRE Directive on the establishment of a common European infrastructure for spatial information to enable easier exchange of data across national borders. In 2015, GEUS took part in three research projects aimed at collecting and harmonising knowledge and data on mineral resources in the EU with a view to securing the supply and sustainable use of mineral resources. The Minerals4EU project was completed and involved development of a portal with information about mining operations and mineral deposits, as well as with access to the European Minerals Yearbook, which contains country-specific information about minerals, production, and imports and exports of mineral resources. Furthermore, work was carried out under the EURARE project, which is developing the foundation for an industry that can secure the future supply of
REE and REE-related products to important European sectors, e.g. the automotive, electronics and chemicals industries. One of the objectives is to develop a database with information on EU REE resources and knowledge about eco-friendly and effective extraction and refining technologies.
Finally, GEUS is part of the ProSUM project to develop databases and a portal with information about opportunities for recycling and secondary sources of critical raw materials in the EU. This is knowledge about volumes and flows of e.g. waste products from industry, waste electronic equipment, batteries, end-of-life vehicles, and waste from mining operations where there is a potential to reuse raw materials.
