July 14, 2008 New book on Greenland geology - 270 pages of popular science
Geological History of Greenland - Four billion years of Earth evolution. This is the title of a new profusely illustrated popular science book on Greenland geology.
- 850 coloured figures describing and explaining the geology
- 60 fact boxes focussing on geological concepts and processes
- 18 page geological glossary (a mini-geological lexicon)
The mountains and fjords of Greenland preserve a record of nearly four billion years of Earth history - a story of mountain building, volcanic eruptions, primitive life and ice ages. During the vast period of time, through processes of continental drift, Greenland has journeyed from the southern hemisphere through the tropics to its present polar position. This volume presents an account of the geological evolution of Greenland, together with its mineral wealth and hydrocarbon potential. It is written in a form that is aimed at the general reader with interest in the dramatic history of our planet.
The book summarises the results of more than 60 years of geological investigations in Greenland and the surrounding shelf areas. It has been written with a professional background and is presented in a form that is suitable not only for the general, interested reader, but also for students and geologists without a specific knowledge of Greenland geology. It includes explanations of basic geological concepts and processes for the non specialist, and describes the potential for economic resources, both onshore and offshore.

February 12, 2008 BIF deposits and mineral potential of pegmatites in Greenland
Pegmatites and their potential for mineral exploitation in Greenland is the title of the recent issue of the magazine Geology and Ore from Geological Survey of Denmark and Greenland (GEUS). The magazine is now available on the web together with a new Fact Sheet on BIF deposits in Greenland.
Pegmatites are important suppliers of many commodities world wide. Geology and Ore No. 10 - January 2008 provides an overview of the genesis and general economic potential of pegmatite occurrences in Greenland. Field observations, archive information as well as maps of stream sediment samples that are enriched in elements characteristic of pegmatites are the base for the presentation. The prospective areas for pegmatite-hosted mineral occurrences in Greenland are outlined, and examples of prominent pegmatite minerals are demonstrated.
Fact Sheet No. 16 on Greenland mineral resources deals with banded iron formation (BIF) deposits. BIF deposits are one of the great iron sources in the world and in Greenland. Here deposits related to banded iron formations (BIF), mostly so-called Algoma type are typical for Archaean greenstone belts formed in continental rift or at continental margins.

January 25, 2008 New geological maps of North and North-East Greenland
1:250.000 geological maps North and North-East Greenland 49 printed new geological maps on a scale of 1:250.000 from North and North-East Greenland are now available from GEUS.
49 new printed geological maps on a scale of 1:250.000 are now available from GEUS. The maps cover the area from 80 degrees north in the western North Greenland over the northernmost tip of Greenland at Kap Morris Jesup and all the way south to Scoresby Sund in central East Greenland.
The maps include many years of geological mapping of the most remote parts of Greenland, and they are based on information from seven 1:500.000 geological map sheets published over a period of 20 years between 1984 and 2004.
Geological mapping of North and North-East Greenland on a scale of 1:500.000 was initiated in 1968 by Geological Survey of Greenland and completed by Geological Survey of Denmark and Greenland (GEUS) in 1998 after many mapping expeditions. The progressive development of the geological understanding of North and North-East Greenland over the past two decades has been incorporated into the new maps. The nomenclature of map units has been made consistent across the original map boundaries and a common geological legend for all the 1:250.000 maps is printed as a separate sheet.
During the mapping from 1968 to 1998 about 100 people participated in the field work each summer. The work was organised as large expeditions operating from base camps. From here geologists were flown out into the mountains to conduct geological mapping on foot from two-man camps. In addition to GEUS´ own geologists, researchers from many institutions in Denmark and abroad have also participated, resulting in an intensified processing of the acquired data.
The printing of the 49 new geological map sheets is financed by the Aage V. Jensen's Foundations.
The topographical as well as the geological data can be found on an interactive map on GEUS' website: arcims.mim.dk/website/GEUS/Greenland/Geo_Neg
The new maps are available from GEUS

Nov. 21 2007 Chalk structure maps - entire Danish territory - now available on the web
The chalk is exposed in the cliff at Stevns in eastern Denmark . Detailed maps of the top, base and thickness of the carbonate rocks under the entire Danish territory are now available on the web. The maps also show deep wells used in the study. Enlarge Three maps of the top, base and thickness of the chalk in the Danish subsurface are now available on the web. The maps also show deep wells used in the study.
Detailed maps of the top, base and thickness of the carbonate rocks under the entire Danish territory are now available on the web. The maps cover the entire area from the central part of the North Sea to the easternmost part of Denmark around the island of Bornholm.
The Chalk in the Danish subsurface is a very important reservoir rock for oil and gas, but in several places the Danes also get drinking water from the limestone strata.
The maps are based on a comprehensive set of data including seismic data, previously published maps and information from over 500 deep oil and gas wells and numerous water wells on land. The maps cover the carbonate rocks and similar geological formations deposited in the period from the Cenomanian to the Danian, and they also show deep wells used in the study. In the North Sea, we find the limestone several kilometres down in the subsurface, and in eastern Denmark, the rocks are exposed, for example in the cliffs at Stevns and on Møn.
The maps are now available on the web as separate downloads for A0 plotter together with a short article:- Top Chalk depth structure map
- Base Chalk depth structure map
- Chalk Group isopach map
- Artikel: Chalk depth structure maps, Central to Eastern North Sea, Denmark
The maps are a part of the publication Review of Survey activities 2006. Geological Survey of Denmark and Greenland Bulletin 13, 2007.
Download the three maps as separate files, the article or the whole publication http://www.geus.dk/publications/bull/nr13/index-uk.htm
