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.

The main object of tho present paper is the consideration of the structure of the Central and S.W. Highlands as shown up by the metamorphic condition of the beds. This metamorphic condition has boon studied over the length and breadth of the country, mapped and deduced from very many outcrops in all districts. Sometimes it was possible to superpose the the details respecting the metamorphism upon the 1-inch maps of the Geological Survey, but in many other cases the areas were mapped upon the 6-inch scale. Naturally this work has taken a long time, for it has necessitated the collection of many thousands of specimens, and nearly 3000 rocks have been sliced and examined, since it is not always possible to define the limits of a metamorphic zone with precision by field work alone, and many rock types were encountered that rendered a more careful study advisable than was possible from the mere examination of a hand specimen.

The programme of field investigations in the north of the Ivisartoq region begun in 1981 by Chadwick & Crewe (1982) was continued in 1982. Julia Park began mapping the Taserssuaq granodiorite, its host rocks and the Ataneq fault in the north-west. Dur team was joined by D. Bellur, Geological Survey of India, nominally as an assistant. In this report we present only summary notes of new findings relevant to the interpretation of the geometry and chronology of this segment of the Archaean crust in southern West Greenland. We use the established terminology for the Archaean rocks of the Godthåbsfjord region.

In 1991 a three year research project was initiated by the Geological Institute, University of Copenhagen with financial support from the Ministry of Energy, the Danish Natural Science Research Council and the Carlsberg Foundation. The 'Wandel Sea Basin: basin analysis' project was carried out in collaboration with the Geological Survey of Greenland and included field work in North Greenland; in eastern Peary Land in 1991 and Amdrup Land in 1993 (Fig. 1; Hakansson et al., 1994). The project is a continuation of earlier investigations in the Wandel Sea Basin carried out during geological mapping of North Greenland by the Geological Survey of Greenland in 1978–1980 and during later expeditions to the area (e.g. Hakansson, 1979; Hakansson et al., 1981, 1989, 1991, 1994). Hydrocarbon related studies of the Wandel Sea Basin were continued during the 1994 field season (Stemmerik et al., this report).

The first record of Middle Cambrian faunas of 'Atlantic' affinity from the Franklinian basin sequence of North Greenland was made by Poulsen (1969) who noted that previously described Greenland faunas were of 'Pacific' type. Field work by the Geological Survey of Greenland during the last decade has established that 'Atlantic' faunas are widespread in more outer shelfsequences along the northern coast of North Greenland while the 'Pacific' faunas occur within inner shelfsequences more to the south, near the margin of the Inland Ice. North Greenland preserves both faunas in dose geographical juxtaposition in only slightly tectonised geological settings. Thus, alatest Middle Cambrian trilobite fauna described by Robison (in press) from the Holm Dal Formation in an area some 40 km south of the presently discussed locality (and more inner shelf) includes a mixture of polymeroids characteristic of the Cedaria Zone of North America and agnostoids characteristic of the Lejopyge laevigata Zone of the Swedish standard zonation.

James Stubblefield

Sir James was born on 6 September 1901 at Cambridge where he attended the Perse School. He received his geological education at Chelsea Polytechnic and the Royal College of Science. In 1923 he was appointed demonstrator in geology at the Imperial College of Science and Technology, London University, where he stayed until 1928; for his last two years there he also served as Warden at the pioneer Imperial College hostel. While at Imperial College he studied the Shineton Shales of the Wrekin district of Shropshire under the guidance of W. W. Watts and in collaboration with his life-long friend O. M. B. Bulman, and was awarded a Ph.D. in 1925. This work in Shropshire provided the stimulus for his continuing contribution on the Cambrian system and its faunas, and on trilobites of all ages. During this period he also recorded his observations on Tertiary crabs from Zanzibar, a group he was to return to in later years. In 1928 he obtained one of the two posts offered by the Geological Survey, being appointed Geologist. He undertook field work in the Dorking district as a prelude to an intended posting to the Survey office at York, but the death of G. W. Lee, then palaeontologist in Edinburgh, determined that Stubblefield should remain at the headquarters of the Survey at Jermyn Street in London. Internal transfers of the palaeontological staff left no member available to determine the fossils then accumulating from the current survey of the Shrewsbury district, and Stubblefield was asked by the Director to undertake this task because of his knowledge of the Lower Palaeozoic faunas of Shropshire. This transfer became long-term and thus began his association with, and eventual leadership of, the Palaeontological Department of the Survey, and secured the continuation of his notable contributions to palaeontology. The Shrewsbury commitment led to visits to the area during which new faunal horizons were discovered in the local Cambrian and Ordovician, including the Nemagraptus gracilis fauna from the Breidden Hills; other finds included the then earliest British eurypterid subsequently described by L. Størmer as the type of a new genus under the name of Brachyopterus stubblefieldi.

James Buckland Mawdsley, M.B.E., Ph.D., F.R.S.C., a Charter Associate of the Arctic Institute of North America, died very suddenly on 3 December 1964 at the age of 70. As Director of the Institute for Northern Studies, University of Saskatchewan, he played a major role in its organization and development and exerted a very great influence on research in northern Canada. He was born on 22 July 1894 near Siena, Italy, the son of British-American parents. In 1904 the Mawdsley family left Italy and settled in the village of Gainsborough, southeastern Saskatchewan. After receiving his public and high school training in Saskatchewan he entered McGill University in 1913. His career, like that of many of his contemporaries, was interrupted by the First World War. Twice wounded in France, first with the Princess Patricia Canadian Light Infantry and then as a pilot with the Royal Flying Corps, he was awarded the M.B.E. at the end of the war. In 1919 he returned to McGill and two years later graduated in Mining Engineering. He then went to Princeton University where he obtained his Doctor of Philosophy degree in Geology in 1924. That same year he joined the Geological Survey of Canada and for the next five years applied his scientific knowledge to the problems of the regional geology of northwestern Quebec. A new chapter in his life began in 1929 when he accepted the appointment of professor and head of the Department of Geology at the University of Saskatchewan, a position he held until he became Dean of Engineering in 1961 and also the Director of the Institute for Northern Studies. In 1963 he retired as Dean and was then able to devote all his time to the affairs of the Institute. In addition to his academic duties his professional activities included field work in northern Saskatchewan for the Geological Survey of Canada and the Saskatchewan Department of Mineral Resources, and private consulting assignments took him to other parts of northern Canada, to the United States and Great Britain. He was the author of 51 scientific papers and his honours were many. He was elected a Fellow of the Royal Society of Canada in 1933 and was chairman of Section IV for the year 1954-55. He was president of the Geological Association of Canada during 1955-56 and of the Canadian Institute of Mining and Metallurgy for 1961-62. In 1953 he was awarded the Institute's Barlow Memorial Medal in recognition of his paper entitled "Uraninite-bearing deposits, Charlebois Lake area, northeastern Saskatchewan". He was a Fellow and Director of the Royal Canadian Geographical Society, a Fellow of the Geological Society of America, a member of the Society of Economic Geologists, the Engineering Institute of Canada, and the Association of Professional Engineers of Saskatchewan. He had an eventful life, travelled widely, met and was a friend to many people. Such qualities as tact, kindliness, sincerity and respect for the thoughts of others enabled him to present his views without arousing undue antagonism, and to cooperate with others in reaching decisions. Recognized as an able administrator, scientist, and teacher, perhaps his greatest service will prove to be the influence he had on those who worked or studied under him. In them he not only instilled a feeling of scientific curiosity but also a keen interest and love of the North.
