AEROMAG 1998 - Aeromagnetic survey - Nuuk, Greenland
The Aeromag1998 survey was conducted in southern West Greenland (size: 31 972 km²). The survey block covered parts of the Archaean craton between 63 deg 40'N and 65 deg 45 ́N. Data are collected and processed by Sanders Geophysics Ltd. and the survey was financed by the Government of Greenland....

Summary: | The Aeromag1998 survey was conducted in southern West Greenland (size: 31 972 km²). The survey block covered parts of the Archaean craton between 63 deg 40'N and 65 deg 45 ́N. Data are collected and processed by Sanders Geophysics Ltd. and the survey was financed by the Government of Greenland. The regular line direction was north-south with orthogonal tie-lines. The regular lines had a separation of 500 metres whereas the tie-lines were flown with a spacing of 5000 metres. The Aeromag 1998 project area covers several known mineral occurrences including the Isua greenstone belt with its iron deposits and gold mineralisations, and part of the West Greenland kimberlite province. The Isua belt is seen as one of the most spectacular anomalies in the area. In the northern half of the survey area, an irregular area between 51 deg W and 52 deg W was excluded because of coverage by an existing data set obtained in 1995 by project AEM Greenland 1995. Magnetic data from this project aremerged withmagnetic data from the Aeromag 1998 project to give a homogeneous data set for the entire region. |
