The survey area for AEM Greenland 1998 (2) is located in the north-eastern J.C. Christensen Land, eastern North Greenland, with additional reconnaissance lines in eastern Peary Land, North Greenland. Measurements included acquisition of controlled source electromagnetic data (GEOTEM -time domain EM) and total field magnetic data.The survey (size of 1603km2) was collected by Geoterrex-Dighem Ltd. and financed by the Government of Greenland. The survey was flown with lines directed along NE45.8 deg and distance between lines of 400 metres. Orthogonal tie-lines were flown with a line separation of 4000 metres. Predominantly sedimentary rocks are exposed in North Greenland. Basin developments are separated by episodes of deformation caused by compressional loading of the crust. Crystalline basement rocks of early Proterozoic and Archean age crop out at the head of Victoria Fjord, but basement rocks have not been located in J.C. Christensen Land. A volcanic unit with widespread occurrence east of Independence Fjord intruded a thick sequence of undeformed Proterozoic sandstones. Rock outcrops in J.C. Christensen Land are controlled by a number of faults. The strikes of the faults are dominantly north-easterly and west-south-westerly; they are considered to be of importance in relation to the Cu-mineralizations reported at several locations within the area. The reconnaissance lines in eastern Peary Land covers the boundary between the Franklinian Basin and the Permian Wandel Sea Basin, which is intersected by a large number of faults. At Citronen Fjord in Peary Land a significant Pb-Zn mineralization was discovered by Platinova A/S in 1993. The mineralization is located in the Ordovician Amundsen Land Group of the Franklinian Basin and is interpreted to be of sedimentary-exhalative type. The overall base metal resource is estimated at 20 million tons stratiform ore of 7% zinc, including 7 million tons containing 9% zinc and 1% lead. The latest update by Ironbark Zinc Limited in 2017 makes this one of the biggest deposits in the world, and preparations for the opening of a mine is ongoing. |
