The present study forms part of a current investigation on the applicability of geochemical methods in mineral exploration in Greenland. The sampling programme of 1981 comprised three parts: (1) A helicopter supported, low density, regional sampling (1 sample/3D km2 ) of stream water and stream sediment in the area covered by map sheet 66 V.2, south-east of Søndre Strømfjord. A total of 207 water samples was obtained. (2) Detailed sampling within a 20 km2 area of lake and stream water (71 samples) from a camp at 66°49'N, 25°37'W, 25 km south-west of Søndre Strømfjord. (3) Reconnaissance sampling, by boat, along the southern part of the west coast of Greenland. The aim of this reconnaissance was to obtain information on the character of the drainage systems and on the availability of sample media (water, stream sediment, aquatic moss) for geochemical exploration. A total of 195 water samples was collected. In addition, rust zones and areas of known mineralisation along the coast were sampled. The present report deals with a study of the water samples only. The following topics will be treated: (1) The variation in pH, conductivity, F and U contents. (2) The effect of filtering and acidifying stream water samples on the results of the measurements. In addition, the logistic conditions for low density sampling of drainage systems will be shortly discussed.

Magmatic Suite

Following a regional reconnaissance stream sediment survey that was carried out in the northern Vosges Mountains in 1983, a total of 20 stream sediment samples were collected with the aim of assessing the regional prospectivity for the granite-hosted base and rare metal mineralisation of the northern Vosges magmatic suite near Schirmeck. A particular focus of the investigation was the suspected presence of W, Nb and Ta geochemical occurrences in S-type (Kagenfels) and I-S-type (Natzwiller) granites outlined in public domain data. Multi-element geochemical assays revealed the presence of fault-controlled Sn, W, Nb mineralisation assemblages along the margins of the Natzwiller and Kagenfels granites. Characteristic geochemical fractionation and principal component analysis (PCA) trends along with mineralogical evidence in the form of cassiterite, wolframite, ilmenorutile and columbite phases and muscovite–chlorite–tourmaline hydrothermal alteration association assemblages in stream sediments demonstrate that, in the northern Vosges, S-type and fractionated hybrid I-S-type granites are enriched in incompatible, late-stage magmatic elements. This is attributed to magmatic fractionation and hydrothermal alteration trends and the presence of fluxing elements in late-stage granitic melts. This study shows that the fractionated granite suites in the northern Vosges Mountains contain rare metal mineralisation indicators and therefore represent possible targets for follow-up mineral exploration. The application of automated mineralogy (QEMSCAN®) in regional stream sediment sampling added significant value by linking geochemistry and mineralogy.
