Geochemical exploration in central and western North Greenland

Abstract

The 1985 geochemical exploration programme in central and western North Greenland completed the present geochemical exploration programme. A total of 424 stream sediment samples were collected during the 1985 field season. The reproducibility of drainage sampling is reasonably good for the elements Ba and Zn. Follow-up of anomalous Ba and Zn values from drainage samples collected in 1984 has not revealed any new mineralised localities. The high contents of Ba and Zn are interpreted as associated with: (1) pyrite-bearing strata, and/or (2) carbonate conglomerate, and/or (3) a higher general content of these elements in some lithostratigraphic units. A known zinc mineralisation in Navarana Fjord, eastern Freuchen Land, contains baryte in addition to sphalerite.
