Erratic Behavior

Gamma‐ray spectroscopy offers a rapid and reliable radiometric method of analysis of uranium and/or thorium ores. Methods of ore analysis are described and experimental results are presented. The uranium‐thorium ratios of rocks, which are important in strata recognition and correlation studies, can be determined directly by gamma‐ray spectroscopy without the necessity of making individual uranium or thorium assays. Analysis of potash ores is facilitated with a gamma‐ray spectrometer. Erratic behavior of gamma‐ray well logs can often be resolved by studying the gamma‐ray spectra of these logs. Neutron‐activation, followed by gamma‐ray spectral analysis, of common earth materials offers a method of borehole rock analysis for elements such as calcium, hydrogen, chlorine, sulphur and magnesium. Data in studies employing radioactive tracers can often be enhanced through use of a gamma‐ray spectrometer. Other present and potential applications of the gamma‐ray spectrometer in mineral exploration are also discussed.

Sampling Programme

A detailed geochemical soil sampling programme was carried out during the field season of 1982 on a known sulphide mineralisation. The aim of the programme is to evaluate soil sampling as a prospecting tool in arctic environments. Previous work by Kunzendorf & Sørensen (1982) on the soil of the nearby Qaqarssuk carbonatite complex has shown promising results for selected elements. The programme also included the collection of rock samples from areas without soil cover. Bedrock is exposed over 5 per cent of the sampling area. The survey was carried out as a part of GGU's resource evaluation programme in West Greenland (Secher, this report). It also forms part of the current investigation of geochemical methods in mineral exploration in Greenland. A total of 1059 soil samples were collected from two areas, both representing soil-covered contacts between bedrock gneiss and Cu-Nisulphide mineralised norite. In addition a total of 112 rock samples were collected. All samples collected during the programme will be analysed for relevant trace elements. The sampled areas are situated about 65 km east of Sukkertoppen, central West Greenland, near the locality Sitdlisigssanguit nunat. The sulphide occurrence was found by the Kryolitselskabet Øresund, who named the locality 'Fossilik'. The two soil sampling areas were covered with regular grids, constructed with the use of a theodolite and with a point density of 25 m. Areas 1 and 2 are 450 x 225 m and 112.5 x 87.5 m, respectively. In Area 1 the slope varies; there are small ridges and hollows; and the altitude varies from 533 m to 593 m. Area 2 is situated on a slope dipping 200 -30° to the south-east, with the altitude varying from 530 m to 572 m.

NOTE: This article was published in a former series of GEUS Bulletin. Please use the original series name when citing this article, for example: Thomassen, B., Kyed, J., Steenfelt, A., & Tukiainen, T. (1999). Upernavik 98: reconnaissance mineral exploration in North-West Greenland. Geology of Greenland Survey Bulletin, 183, 39-45. https://doi.org/10.34194/ggub.v183.5203 _______________ The Upernavik 98 project is a one-year project aimed at the acquisition of information on mineral occurrences and potential in North-West Greenland between Upernavik and Kap Seddon, i.e. from 72°30′ to 75°30′N (Fig. 1A). A similar project, Karrat 97, was carried out in 1997 in the Uummannaq region 70°30′–72°30′N (Steenfelt et al. 1998a). Both are joint projects between the Geological Survey of Denmark and Greenland (GEUS) and the Bureau of Minerals and Petroleum (BMP), Government of Greenland, and wholly funded by the latter. The main purpose of the projects is to attract the interest of the mining industry. The field work comprised systematic drainage sampling, reconnaissance mineral exploration and spectroradiometric measurements of rock surfaces.
