As a first stage in planning a regional mapping programme on the south-east coast of Greenland from Scoresby Sund to Kap Farvel, the available material from previous expeditions has been examined and a provisional geological map is being compiled. A programme of isotopic age determination has been started in collaboration with F. J. Fitch (London University) and J. A. Miller (Cambridge University) in order to help localise areas in which to concentrate future detailed geological mapping. The Geological Survey of Greenland will be very pleased to receive information gathered on recent expeditions to this coast which may be of help in planning and which could prevent a senseless dupliaation of effort.

The publication of the 1:500 000 Skjoldungen map sheet (Escher, 1990; Fig. 1) marks the completion of the Geological Survey of Greenland's (GGU's) reconnaissance mapping activities in South-East Greenland. A descriptive text to the map is under preparation. All of South-East Greenland between Kap Farvel (59° 00´N) and Mesters Vig (72° 00´N) is now covered by sheets of the 1:500 000 geological map series of Greenland. Five sheets in the series (nos 5,6,9, 10 and 11) remain to be published (Fig. 1); the Thule map sheet (sheet 5) will be printed in the course of 1991, and sheet 10 is under compilation. The presentation of the Skjoldungen map is somewhat different from that of the other 1:500 000 maps inthe series. In addition to traditional lithological information, an effort has been made to show the tectonic/metamorphic development of the region during the Archaean and Proterozoic.

The first recorded landing by Europeans on the coast of northern East Greenland (north of 69°N) was that of William Scoresby Jr., a British whaler, in 1822. This volume includes a chronological summary of the pioneer 19th century exploration voyages made by British, Danish, Norwegian, Swedish, French and German expeditions – all of whom reported that the region had previously been occupied by the Inuit or Eskimo; also included are brief outlines of the increasing number of government and privately sponsored expeditions throughout the 20th century, whose objectives included cartography, geology, zoology, botany, trapping and the ascent of the highest mountain summits. In 1934 the Place Name Committee for Greenland was established, the tasks of which included a review of all place names hitherto recorded on published maps of Greenland, their formal adoption in danicised form, and the approval or rejection of new name proposals. In northern East Greenland, by far the largest numbers of new place names were those proposed by scientists associated with Lauge Koch's geological expeditions that lasted from 1926 until 1958. This volume records the location and origin of more than 3000 officially approved place names as well as about 2650 unapproved names. The author's interest in the exploration history and place names of northern East Greenland started in 1968, when the Geological Survey of Greenland initiated a major five-year geological mapping programme in the Scoresby Sund region. Systematic compilation of names began about 1970, initially with the names given by William Scoresby Jr., and subsequently broadened in scope to include the names proposed by all expeditions to northern East Greenland. The author has participated in 16 summer mapping expeditions with the Survey to northern East Greenland. Publication of this volume represents the culmination of a lifetime working in the Arctic.

NOTE: This article was published in a former series of GEUS Bulletin. Please use the original series name when citing this article, for example: Sørensen, K. (2001). The year in focus, 2000. Geology of Greenland Survey Bulletin, 189, 7-10. https://doi.org/10.34194/ggub.v189.5148 _______________ The year 2000 was unusual in that it lacked major field activity directly involved with the systematic geological mapping of Greenland. However, field activities were again many and varied, including a successful highresolution seismic survey offshore central West Greenland, and a joint Geological Survey of Denmark and Greenland (GEUS) – Danish Lithosphere Centre (DLC) project centred on Kangerlussuaq in southern East Greenland. Of the Survey’s 354 personnel, 93 were allocated to Greenland-related activities (Table 1). The Greenland level of activity in 2000, both in Copenhagen and in the field, thus compared favourably with that of 1999.

A three-year field mapping programme was initiated in 1988 aiming at regional geological studies and geological mapping in North-East Greenland between latitudes 75° and 78°N. This region encompasses relatively little known parts of the Caledonian fold belt and the overlying post-Caledonian sequences, which lie north of the better known regions of central East Greenland (Henriksen, 1989). Major aims of the programme include compilation a 1:500 000 geological map, and an understanding of the general geology of the region.

The road-cuts and other new excavation works provide an excellent opportunity for upgrading the geological maps in Poland. Such opportunity should not be missed. Updating The Detailed Geological Map of Poland at the scale of 1:50 000 should be the priority. Ephemeral nature of the freshly cut outcrops makes this research rather urgent. It would require an adequate planning and organization. Geological mapping based on the new road-cuts and rock sections exposed by new investments should be one of the main tasks of the Geological Survey of Poland.

The career of Jean-Baptiste-Julien d'Omalius d'Halloy (1783-1875), commencing with brilliant scientific activities and proceeding to his attainment of the highest administrative and political positions, in itself demonstrates that he was an exceptional individual. His scientific career started with a long voyage through the French Empire and adjacent regions, during which he gained an understanding of the geological structure of most of Europe. The geological map he compiled based on his travel notes formed the basis of all future geological maps in the areas that he covered. After the independence of Belgium in 1830, André Dumont was made responsible for the mapping of the whole country, resulting in the publication of a 9-sheet map of Belgium in 1853 on a scale of 1:160.000. In 1878, Belgium decided to produce a more detailed map on the scale of 1:20.000, entrusting the work to Edouard Dupont., but as this appointment was controversial and the mapping at this scale was abandoned and than, the newly created Geological Survey of Belgium published a new 226-sheet map on a scale of 1:40.000. Starting from 1993, after the federalisation of the country, new geological maps of the regional states are mapped and produced.

The Geological Survey of Greenland (GGU) carried out in 1970 the third summer of mapping in the crystalline complex of the Scoresby Sund region. The region mapped was the continuation southwards of that mapped the previous two summers in the inner fjord zone. The main geological divisions encountered correspond generally to those aIready known and described briefly by Henriksen & Higgins (1969, 1970). The 1970 mapping of the crystalline complex was a team project in which eight geologists participated. Each geologist mapped about 500-600 km2 in a field season of about six weeks. While excellent exposures facilitated the work extensive use of helicopters was necessary to cover the region in the time available and some parts, can only be considered as mapped to a reconnaissance standard. Topographical maps at a 1:50 000 scale, enlarged from 1:200 000 originals, were used for compilation of geological results and extensive use was made of oblique and vertical aerial photographs. The geologists participating during 1970 were: B. Chadwick, Exeter; J. D. Friderichsen, Copenhagen; N. Henriksen, Copenhagen; A. K. Higgins, Copenhagen; P. Homewood, Lausanne; L. Jemelin, Lausanne; H. Rutishauser, Bern and K. Sørensen, Aarhus. The areas mapped by each geologist are shown on the key of the geological map (map 1). This report is based on information supplied by all the geologists and many of the views presented originated from other members of the mapping team. However, the writers are responsibIe for the interpretations given in this paper which do not necessarily coincide exactly with those of their colleagues. In due course many of the geologists will present detailed accounts of their individual areas and GGU plans to publish 1:100 000 map sheets of the region.

Since Guettard presented his geological map of North America in 1752, over 100 geological maps were produced that cover all or parts of West Virginia up to 1897, when the State Geological Survey was formed. Their quality, accuracy, scale, and general content vary widely, but each contributed to our growing understanding of West Virginia and Appalachian geology. This annotated, chronologic list of maps illustrates this wide diversity and steady improvement of early geological mapping.

North-East Greenland is the last major area that remains to be geologicaIly mapped in the programme of regional mapping at a scale of 1:500000. In 1988 a three-year field mapping programme was initiated aimed at regional geological studies and geological mapping in the area between 75°N and 78°N. The southern third of this region (75°-76°N) is included on the map at a scale of 1:250000 by Koch & Haller (1971), and the n0rthern part forms part of a map at a scale of 1:1 000000 (Haller, 1983). However, the region as a whole has previously only been studied on a reconnaissance basis with limited ground control, and the published maps make extensive use of aerial photograph interpretation.
