The Geological Survey of Denmark and Greenland (GEUS) has produced a new digital compilation of diamond exploration data from West Greenland:
Jensen, S.M., Secher, K., Rasmussen, T.M. & Schjøth, F. 2004: Diamond exploration data from West Greenland: 2004 update and revision.
Danmarks og Grønlands Geologiske Undersøgelse Rapport 2004/117, 90 pp. (1 DVD included).

The new digital data and GIS compilation (on DVD) is an updated and completely revised edition of the first version published in 2003. The main improvements are the following:

• Twenty assessment reports from exploration companies submitted to the Bureau of Minerals and Petroleum have been added, and there are now 164 scanned reports in Adobe PDF documents
• The amount of data has been nearly doubled as a result of expiry of confidentiality. There are now approximately 96 150 mineral analyses from 15 295 samples of till or stream sediment from 4563 localities, and 2780 mineral analyses from 31 kimberlitic rock samples
• All mineral chemistry data have been examined, and analysed kimberlite indicator mineral grains have been classified and plotted in 560 classification diagrams
• All available geophysical maps have been scanned in large format, and are presented in Adobe PDF documents. Approximately 300 maps have been added
• The number of observations of kimberlitic rocks has been nearly doubled to approximately 2700
• Topographic data at 1:100 000 scale are included for the regions of current diamond exploration
