| 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 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:

| September 14, 2007 Lithostratigraphy of the Danish North Sea, Palaeogene - Lower Neogene succession New Bulletin from Geological Survey of Denmark and Greenland with revised lithostratigraphic framework for the siliciclastic Palaeogene to Lower Neogene sediments of the Danish sector of the North Sea. In the mid-1990s, hydrocarbon exploration in the Danish sector of the North Sea shifted from Mesozoic targets to the lower Cenozoic, particularly in the so-called 'Siri Canyon', an erosional feature incised into the top of the Chalk on the eastern flank of the Central Graben. Intensive drilling activity in subsequent years has provided a wealth of new information concerning the nature of the Cenozoic sedimentary succession in this region and has also illustrated the need for a refined, up-dated lithostratigraphic framework. This bulletin presents the lithostratigraphy of the marine siliciclastic Palaeogene - Lower Neogene succession of the Danish North Sea. Existing groups (three) and formations (seven) defined elsewhere in the North Sea region are adopted and supplied with reference wells; eleven new members are defined from the Danish North Sea succession.

| September 11, 2007 New maps of North and North-East Greenland - 10 times the size of Denmark on paper  1:250 000 topographic maps North and North-East Greenland Some of the Earth's most inhospitable areas have now been mapped. The wilderness and rugged mountains of North-East Greenland can now be studied on printed maps, published by GEUS. The 53 new 1:250 000 map sheets cover the area from the western North Greenland near Qaanaaq over the northernmost tip of Greenland at Kap Morris Jesup and all the way south to Scoresby Sund in central East Greenland. The new topographic maps cover land and glacier areas about 10 times the size of Denmark and contain information about coastlines, lakes, rivers and contour lines for every 100 m. The National Survey and Cadastre (KMS) has previously published 1:250 000 topographic maps of other parts of Greenland. This means that almost the entire land area of Greenland is now covered on this scale. Design as well as division of the new map sheets follows KMS' earlier production. The modern geodetic survey of North and North-East Greenland was started by KMS in the 1970s and at the same time GEUS had a pronounced need for detailed topographic maps of the area in connection with the geological mapping. GEUS started compiling maps in 1978 from aerial photographs, taken by KMS during the period from 1978 to 1987. The work took place concurrently with the geological mapping of North and North-East Greenland which was done primarily from the early 1980s to the end of the 1990s. The printing of the 53 new map sheets is financed by the Aage V. Jensen's Foundations and later this year GEUS will publish the corresponding 1:250 000 geological maps. 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 topographic maps are available from GEUS |
| May 6, 2007 Reworked Archaean and Palaeoproterozoic rocks - New geological map sheet description The Ussuit map area at the edge of the Inland Ice in central West Greenland displays reworked Archaean and Palaeoproterozoic rocks in the core of the c. 1850 Ma Nagssugtoqidian orogen. Also the brittle fault systems, predominantly of Mesozoic and Cenozoic ages, and Quaternary deposits are indicated. In addition to a systematic description of the map units, these explanatory notes comprise accounts of the geoscientific research and of the Palaeoproterozoic geological evolution in this key area of the Nagssugtoqidian orogen. Previously unpublished geochronological data are presented in full in an appendix. Aeromagnetic data, surface geochemical data and economic geology are presented in three separate sections. Several occurrences of iron sulphides with minor copper are known, and the area holds a potential for industrial minerals and dimension stones.

| March 27, 2007 New managing director of GEUS  Johnny Fredericia - download high res.photo (~2 mb) Since 1998 Johnny Fredericia has been a vice-director of GEUS, a position he took after eight years as state geologist and head of the Department of Quaternary and Marine Geology. He received his education as geologist at the University of Copenhagen and later took a Ph.D. degree in hydrogeology at the Technical University of Denmark. Johnny Fredericia's many-sided career includes research co-operation and networking with trade and industry. The new director has wide experience of managing research, staff and institution, and one of his coming duties will be to implement the new Geocenter Denmark - a formalised co-operation between GEUS, two institutions of the University of Copenhagen, viz. the Department of Geography and Geology and the Geological Museum, and the Geological Institute of the University of Aarhus. |
| March 16, 2007 New geological guide to South Greenland - 132 pages of popular science for your tour "Geological Guide - South Greenland" is the title of a new popular science book from Geological Survey of Denmark and Greenland (GEUS). It is a handy guide book to the exciting geology of the Narsarsuaq - Narsaq - Qaqortoq region of South Greenland which houses some world-famous mineral localities. The area includes the Ilímaussaq complex, which is one of the world's most fascinating igneous complexes because of its extreme enrichment in rare elements expressed in more than two hundred and twenty-five different minerals and in unique multi-coloured rocks. Thirty minerals were first discovered and described in the complex and twelve are unique to it. The guide focuses on the description of the main geological features of the region and includes 18 tour descriptions as well as a chapter on mineral collecting. It is richly illustrated with colour photos and graphics together with many topographical and geological maps. The book is designed as a handy guide in A5 format to be used in the field. The target group is the visitors who would like to know more about the geology of the region or become fascinated by its mountains, glaciers, multi-coloured rocks and minerals.
