Gold Bearing

The search for gold in Greenland has hitherto been concentrated in geological terrains such as Precambrian volcanics that elsewhere on earth are traditionally regarded as gold-bearing. However, as it happens, the first exploitation of gold in Greenland could well be from a truly new type of gold mineralisation.

Geological Implication

Labradorite phenocrysts of basaltic rocks collected from the moraine of Daugaard-Jensen Gletscher in Scoresby Sund, East Greenland, have been studied by U-stage methods. lnterpenetrating fourlings after (010) have the axis [001) in common. The (010) planes of the two fourlings form an angle of 38° ± 1° in the example illustrated. Two rectangular planes of symmetry between the two systems intersect in [0(ll], but are not developed as morphological boundary planes. These symmetry planes bring the twin axes of the Albite, Carlsbad and Albite-Carlsbad laws of one fourling into the position of those of the second four­Iing. The same mirror reflection brings the vibration directions na, nf3, ny of each individual of the first fourling into the position of corresponding indicatrix axes of an individual of the second fourling. As a sec­ond interpenetration with common [001) but with an angle of 52° between the planes (010) has been found, we conclude that the coinciding axis [001) is the characteristic feature of this new type of inter­growth. A geological implication from this study is the proof for the occurrence of basalt in the bed-rock below the ice cap west of Daugaard-Jensen Gletscher, 150 km north of the northernmost extension of the thick pile of plateau basalts of the Brito-Arctic province along the East Coast of Greenland.

Geology of Greenland Survey Bulletin, 189, 76-80. https://doi.org/10.34194/ggub.v189.5161 _______________ A zone of hydrothermal veins in the Kangerlussuaq region, southern East Greenland, is the focus of a oneyear project by the Geological Survey of Denmark and Greenland (GEUS). The project aims to localise, map, sample and analyse silver-gold-bearing veins in a selected area of Precambrian and Palaeogene rocks north of Amdrup Fjord (Figs 1, 2). This report describes the field work and presents some preliminary results. The study area comprises a c. 3 km wide and 10 km long ridge between Amdrup Fjord and Søndre Syenitgletscher, centred on the 938 m high mountain Flammefjeld (Figs 2, 3). The area is of alpine character with small glaciers and with extensive snow cover most of the year. The field programme was chosen to coincide with the time of minimum snow cover, from 25 July – 23 August. During this period, the major part of the area was investigated on daily foot traverses from four fly camps, helped by helicopter lifts on two occasions. Logistically, the work was part of a larger expedition to East Greenland – EG 2000 – organised by the Danish Lithosphere Centre and GEUS, which is reported on elsewhere (Nielsen et al. 2001, this volume). A temporary field base in Sødalen, some 50 km east of Amdrup Fjord, supported the expedition’s Ecureuil AS 350 helicopter and provided services for the field teams of the various activities attached to EG 2000. Air connections with Iceland were maintained by Twin Otter aircraft operating from a gravel landing strip in Sødalen (Fig. 1).

New Type

A new type of meniscus filled tunnel is described and designated Ancorichnus ancorichnus n. ichnogen., n. ichnosp. The trail is functionally analysed in terms of the anchor method used by soft bodied animais in penetrating soft substrates. The whole trace fossil assemblage, consisting of Ancorichnus, Planolites, Muensteria, small meniscus tunnels and Gyrochorte, is described. The structure and trophic groups of the different meniscus filled tunnels are compared.

The SUPRASYD project is a reassessment of the geo­tectonic setting and mineral potential of the Lower Proterozoic Ketilidian orogenic belt in southern Greenland (previously described by Allaart, 1976 and Kalsbeek et al., 1990), and in particular its supracrustal rocks. During the first field season in 1992 a geological and geochemical reconnaissance programme was carried out in South-East Greenland between approximately latitudes 60° to 62° N, mainly in areas with supracrustal rocks (Steenfelt et al., 1992; Nielsen et al., 1993; Chadwick et al., 1994a). The second season in 1993 focused on the southern part of the Julianehab batholith on the west coast of South Greenland, as well as on shear zones with spatially associated gold mineralisation (Garde & Schonwandt, 1994; Chadwick et al., 1994b; Stendal et al., in press). Field work from the early 1960s was re-evaluated and supplemented with new mapping with the aim of compilation of the 1: 100 000 scale map sheet 60 V.3, Sondre Sermilik.

The following notes are based on impressions gained during my stay among Eskimo and European trappers at Clavering Øya, North-East Greenland, in 1939–40. Much attention has been focused on the problem of sledge dogs by European trappers, for during the trapping season they have to depend on their dogs because of the long distances that have to be covered. In an attempt to develop a new type of sledge dog, with the endurance of a Greenland Husky and the speed of an Alsatian, many attempts have been made during the last ten years to breed dogs with these special qualities in view.
