Thirty-two radiocarbon age determinations of bivalve shelIs (30), gyttja (1) and peat (1) are summarised below. All but two of the samples were collected during the GGU geological expedition to the Peary Land region. Two samples comprise contemporary shelIs from north and north-east Greenland, and were collected earlier. The samples have been dated at the Carbon-14 Dating Laboratory of the Geological Survey of Denmark and the National Museum, Copenhagen (samples marked K, by courtesy of the Geological Survey of Denmark), the C-14 Laboratory at the Department of Quatemary Geology, University of Lund, Sweden (samples marked Lu, by courtesy of the laboratory and the Department of Quatemary Geology, University of Lund), and the Harwell Carbon 14/Tritium Laboratory, AERE, England (samples marked HAR).

AbstractAn assemblage of 50 species of small shelly fossils is described from Cambrian Series 2 (Stage 4) strata in North Greenland, the present day northernmost part of the paleocontinent of Laurentia. The fossils are derived from the basal member of the Aftenstjernesø Formation at Navarana Fjord, northern Lauge Koch Land, a condensed unit that accumulated in a sediment-starved outer ramp setting in the transarctic Franklinian Basin, on the Innuitian margin of Laurentia. Most other small shelly fossil assemblages of similar age and composition from North America are described from the Iapetan margin of Laurentia, from North-East Greenland south to Pennsylvania. Trilobites are uncommon, but include Serrodiscus. The Australian bradoriid Spinospitella is represented by a complete shield. Obolella crassa is the only common brachiopod. Hyoliths, including Cassitella, Conotheca, Neogloborilus, and Triplicatella, are abundant and diverse, but most are represented just by opercula. Sclerites interpreted as stem-group aculiferans (sachitids) are conspicuous, including Qaleruaqia, the oldest described paleoloricate, Ocruranus?, Inughuitoconus n. gen., and Hippopharangites. Helcionelloid mollusks are diverse, but not common; they are associated with numerous specimens of the bivalve Pojetaia runnegari. The fauna compares best with that of the upper Bastion Formation of North-East Greenland, the Forteau Formation of western Newfoundland, and the Browns Pond Formation of New York, but several taxa have a world-wide distribution. Many specimens are encrusted with crystals of authigenic albite. New species: Anabarella? navaranae, Stenotheca? higginsi, Figurina? polaris, Hippopharangites groenlandicus, Inughuitoconus borealis, and Ocruranus? kangerluk.UUID: http://zoobank.org/160a17b1-3166-4fcf-9849-a3cabd1e04a3

The second field season of the Geological Survey of Greenland's (GGU) mapping project in eastern North Greenland (1993–95) was carried out according to plan and with full accomplishment of all geoscientific goals. The programme aims at producing a general overview of the onshore geology of the Jokelbugten to Kronprins Christian Land region (78–81 °N) in eastern North Greenland (Fig. 1) to be compiled as sheet no. 9 in GGU's 1:500 000 geological map sheet series; this is the last remaining incomplete map sheet at this scale in North and North-East Greenland. The field work was initiated in 1993 with limited reconnaissance work (Henriksen, 1994a), and in 1994 the first of two more intensive field campaigns was carried out. In addition to establishing a general overview of the regional geology the work aims at obtaining an evaluation of the economic geological potential of the region, in respect of both minerals and hydrocarbons. Two glaciological programmes were fully integrated with the project: one was carried out by the Alfred Wegener Institute (AWi), Bremerhaven, Germany, while the other was partly based on a special grant from the Nordic Council of Ministers.

As part of studies of the onshore hydrocarbon potential in East Greenland undertaken by the Geological Survey of Greenland (GGU), a project was initiated with the purpose of describing the dinoflagellate cyst stratigraphy of the Lower Cretaceous succession in East Greenland (72°76°N) and correlating the exposed sections throughout the region (Nøhr-Hansen, 1993). Based on the rather sporadic occurrence of macrofossils the Lower Cretaceous sediments of East Greenland was previously dated as Aptian to Albian (Spath, 1946; Maync, 1949; Donovan, 1953, 1955, 1957). Maync (1949) reported the total exposed thickness of the ‘Aptian-Albian series’ to be more than 2000 m, whereas Surlyk (1990) noted that the Lower Cretaceous shale succession reached a cumulative thickness or 1000 m. Furthermore, Donovan (1972) reported that Hauterivian and Barremian sediments were unknown in East Greenland. Dinoflagellate cysts recorded from 40 sections throughout the region have now dated the Lower Cretaceous sequence as Barremian to Albian, and correlation of sections yields a cumulative thickness of approximately 1500m (Nøhr-Hansen, 1993).

In 1986 the Geological Survey of Greenland (GGU) initiated a major field and laboratory programme in the onshore areas of North-East Greenland in order to evaluate the petroleum potential and provide basic petroleum geological information for future exploration in the region (Fig. 1).

Svalbard is part of the Old Red Sandstone province with affinities in East Greenland, Norway, Appalachian North America and, of course, the British Isles where the Devonian Period was defined. This allows Devonian history in this region, controlled by Caledonian events, to form a neat and natural chapter, though not necessarily a global one. Old Red Sandstone environments in each area were already becoming established in Late Silurian time. Olaf Holtedahl was the prime author of both Caledonian tectogenesis in Svalbard and the Old Red Sandstone aftermath.Of the many and varied biotas of Svalbard the fossil fish have made remarkable and classic contributions to Spitsbergen geology.The earliest 'Old Red Sandstone' Spitsbergen strata have yet to yield evidence of age and so may be latest Silurian (Siktefjellet Group). But the earliest Devonian strata to be identified biostratigraphically begin with the Red Bay Group. Similarly the (major) Ny Friesland Orogeny and the various late orogenic granite emplacements, while initially Silurian, continued at least to cool in Devonian time. For convenience the orogenic events that may continue as early Devonian are treated in the Silurian chapter and the sedimentary events that may be Silurian are treated here.Devonian successions in Svalbard are known only from terranes which are postulated to have originated from the North East Greenland Province. No record has yet been established for Devonian strata in Svalbard either from the eastern terranes (East Greenland Province) or from the western terranes (North Greenland-Pearya Province). Moreover, the East Greenland succession lacks

SynopsisA gravity survey has been made of a glacier-dammed lake in Dronning Louise Land, North-East Greenland. Corrections for the effect of the local topography and the regional Bouguer anomaly are made to the values of the acceleration due to gravity measured at about 230 points on the lake and its shores. From the differences between the corrected values at the lake stations and those of the shores, depths of water under the lake stations are calculated, and a contour map of the lake bottom is drawn. A submerged shelf, 75 metres below the present lake level, persists around the western part of the lake. This may be the shore-line of a pre-glacial lake.
