Kort over israndslinjer og lokaliteter i Skandinavien
Kort over israndslinjer og lokaliteter i Skandinavien. Kortet viser den gradvise afsmeltning af den skandinaviske iskappe under den sidste istid. Kortet viser iskappens udbredelse i 5 perioder inden for de sidste ca. 20 000 år, eksisterende iskapper, israndslokaltiteter, israndslinjer og hypotetiske israndslinjer. Kortet er fremstillet til visning i 1:1 million.
Datapakken indeholder kortet som PDF fil samt i shape format til brug i GIS samt den tilhørende publikation "Israndslinier i Norden" udgivet af Nordisk Ministerråd i TemaNord 1998:584

AEM Greenland 1996 - A combined helicopter-borne electromagnetic, magnetic, radiometric and VLF-EM survey at Sermiligaarsuk North, Midternæs, Grænseland, Sioralik South and Arsuk Ø survey blocks, Southwest Greenland
The area of the AEM 1996 survey is located in the Grønnedal region, South-West Greenland. Five separate blocks were surveyed, primarily covering the Ketilidian (early Proterozoic) and Tartoq (Archean) supracrustal belts. The multi-sensor, helicopter geophysical survey system including multi-frequency HEM system, magnetometer and VLF-EM sensors were placed in two birds below the helicopter, but the gamma ray spectrometer was mounted on the helicopter platform. The survey (extent of total area: 1560 km2) was performed by Aerodat Inc. and financed by the Government of Greenland. It was flown at a mean helicopter terrain clearance of 60 metres with survey lines spaced at 200 metres and orthogonal tie-lines at 2000 metres.
The Archean is dominated by 2.7 to 2.9 Ga old gneisses, but contains the older Tartoq Group supracrustals consisting of mafic to ultramafic metavolcanic units with subordinate felsic metavolcanic or metasedimentary rocks intruded by a granitoid dated at c. 2.944 Ga. The Archean basement is unconformably overlain by Ketilidian supracrustal rocks and is intruded by Ketilidian dolerite dykes and granites. The supracrustal rocks are almost unmetamorphosed at Midternæs, while the metamorphic grade increases to amphibolite facies in southern Grænseland and Arsuk Ø.
The survey blocks are situated near the southern Archean boundary of West Greenland and were initially selected to cover both Proterozoic and Archean supracrustal belts with a potential for economic base metal or precious metal mineralisation.The multi-frequency EM survey mapped a large number of bedrock conductors, particularly within the Ketilidian rocks of Midternæs and Grænseland
