AEM Greenland 1998 (1) - Airborne GEOTEM & magnetic survey over Washington Land & Daugaard Jensen Land in western North Greenland
No full textThe AEM Greenland 1998 (1) survey was conducted in Washington Land and Daugaard-Jensen Land in western North Greenland. Measurements included acquisition of controlled source electromagnetic data (GEOTEM -time domain EM ) and total field magnetic data. The survey (size of 3220 km2) was flown by Geoterrex-Dighem Ltd. and financed by the Government of Greenland. Two surveys were acquired. The main survey was flown with a flight line spacing of 400 metres between lines with a heading of NW23.5 deg and tie-lines at a direction of NE66.5 deg spaced 4 km apart. Within this area, a smaller survey in the eastern part directly over the mineralised sites was measured at 200 m line spacing (NE66.5 deg).
During a GEUS geological reconnaissance campaign in eastern Washington Land in 1997, a Zn-Pb-Ag mineralisation was discovered in dolomitic boulders in the area. The discovery led to the selection of Washington Land and Daugaard-Jensen Land as one of the target areas in North Greenland for a combined airborne electromagnetic (GEOTEM) and magnetic survey.
Lower Palaeozoic sedimentary deposits dominate the geology of Washington Land and Daugaard-Jensen Land. The sediments were deposited in the Franklinian Basin that has an extension of approximately 2000 km across North Greenland and Canada. Approximately 8 km of Lower Palaeozoic strata are exposed within the North Greenland part of the basin. In Washington Land and Daugaard-Jensen Land the depositional environment of the basin is reflected in shelf sediments located to the south and deep-water sequences further to the north. Exposed rocks in the survey area consist mainly of carbonates deposited on the former shelf with subordinate siliciclastic sediments and evaporites.
The Zn-Pg-Ag mineralisation is found within the evaporite-rich part of the Lower Ordovician platform sediments
