GEOLOGY OF GREENLAND SURVEY BULLETIN 189 • 2001 Review of Greenland activities 2000 Edited by A.K. Higgins and Karsten Secher GEOLOGICAL SURVEY OF DENMARK AND GREENLAND MINISTRY OF ENVIRONMENT AND ENERGY
Geology of Greenland Survey Bulletin 189 Keywords Climatic research, Greenland activities 2000, hyperspectral survey, limnology, marine geophysics, mineral resources, petroleum geology, publications review, sedimentology, stratigraphy. Cover The Nalunaq gold prospect, South Greenland, has been in focus in 2000 with test mining for feasibility studies. The scene features the east face of the Nalunaq mountain, the summit of which is 1100 m above the temporary mining camp situated on the valley floor. The winding road provides access to the adit portals at exploration levels 350, 400 and 450 m (see the article on Nalunaq gold prospect, page 70). Photo: Hans Christian Langager. Frontispiece: facing page Swarm of hydrothermal veins (‘Yellow Zone’) situated at the margin of a Palaeogene breccia pipe (upper right) north of Amdrup Fjord, southern East Greenland. The person clad in red in the centre of the picture is collecting a chip sample, which returned 0.8% Cu, 1.4% Pb, 3.2% Zn, 0.3 ppm Au and 127 ppm Ag over 4 m. The photograph was taken during EG 2000 (see Nielsen et al., page 83 and Thomassen & Krebs, page 76) and the investigations demonstrate that the area holds a potential for vein-type gold and silver deposits.
