AEROMAG 1995 - High sensitivity aeromagnetic survey, South Greenland ...
Most of South Greenland (south of 62 deg N) was covered by the Aeromag 1995 survey (size: 39 902 km²). Data were acquired and processed by Sanders Geophysics Ltd. and financed by the governments of Greenland and Denmark. The survey lines are oriented N30W and spaced at 500 metres intervals. Tie-line...

| Summary: | Most of South Greenland (south of 62 deg N) was covered by the Aeromag 1995 survey (size: 39 902 km²). Data were acquired and processed by Sanders Geophysics Ltd. and financed by the governments of Greenland and Denmark. The survey lines are oriented N30W and spaced at 500 metres intervals. Tie-lines were flown at 5 000 metres intervals in an orthogonal direction to the survey lines. The main geological units in the survey area are theArchean craton to the north and the Palaeoproterozoic Ketilidian orogen to the south. The Palaeoproterozoic Ketilidian orogenic belt can be divided into four zones: the Border zone, the Julianehåb batholith, the Psammite Zone and the Pelite Zone. The Aeromag 1995 project covers most of the Ketilidian mobile belt and the boundary to the older Archean rocks to the north. The boundary between the two regions is at the west coast placed near 61o30'; north of this is what is usually referred to as 'the border zone'. A part of the Archean craton is to varying degrees overlain by the ... |
