Joint Group

Field work was carried out from 17 July to 3 August by a joint group from ARCO, AGIP and GGU to evaluate the reservoir potential of the Upper Permian limestones in Wegener Halvø (fig. 1). The group was based south of Paradigmabjerg (fig. 1) and had a Bell 206 helicopter available tull-time during the entire period. Logistic support was provided by the ARCO base at Constable Pynt. The Upper Permian limestones in the Wegener Halvø area have been investigated previously by GGU (Stemmerik, 1979; Surlyk, 1983; Surlyk et al., 1984a,b, 1986a; Hurst et al., 1989). Diagenetic studies of the limestones (Scholle, 1986; Hurst et al., 1989) indicate that reservoir properties are expected mainly to occur in the bryozoan-cement mounds of the Wegener Halvø Formation. Accordingly, the 1988 programme concentrated on more detailed studies of these mounds and included a shallow drilling programme conducted by GGU (see Christiansen & Stemmerik, 1989).

Reservoir Potential

The Upper Permian Wegener Halvø Formation buildups form an important reservoir target in the Jameson Land basin. Due to absence of subsurface information from the basin, reservoir properties of the buildups are tentatively evaluated by timing the different diagenetic modifications seen in outcrop relative to hydrocarbon migration.The buildups became cemented during deposition and the ultimate porosity was dose to zero. Post-depositional porosity appears to be related to freshwater dissolution of aragonite cement during Permian exposure events. Reservoir potential is mainly confined to the buildup cores and the proximal flank deposits. Porosity prior to hydrocarbon migration is estimated to average 10% in the buildups and 5–6% in the proximal flank deposits. Pores became filled by hydrocarbons probably in the Late Cretaceous; the reservoirs became flushed by hot, hydrothermal fluids c. 20 Ma ago and pores are now filled by iron-rich calcite, baryte and fluorite. The flushing of the reservoir may be related to the Tertiary uplift of Wegener Halvø, and it is most likely a local event not affecting the basin as a whole.

During field work in the Upper Permian of Scoresby Land, a number of thin lamprophyric dykes were found in the area around Revdal (fig. 36). Direct fjeld evidence indicates a Late Permian age for at least some of these dykes. Such dykes are known to occur elsewhere in East Greenland (Haller, 1971, fig. 122), where some are thought to be of Devonian age (Haller, 1971).

Peritidal Carbonates

The depositional pattern of the Upper Permian Wegener Halvø Formation is mainly controlled by the karst topography of the surface of the underlying Karstryggen Formation. The area was divided by a NNW–SSE trending depositional and/or erosional high during Late Permian times. Peritidal carbonates and evaporites are dominant on the platform to the west while to the east oolite and biogene grainstone deposits dominate. Reservoir-quality properties are mainly confined to the grainstone deposits east of the high.

Geology of Greenland Survey Bulletin, 176, 29-38. https://doi.org/10.34194/ggub.v176.5058 _______________ The multidisciplinary research project ‘Resources of the sedimentary basins of North and East Greenland’ was initiated in 1995 with financial support from the Danish Research Councils (Stemmerik et al., 1996). In 1996, the hydrocarbon-related studies focused on the sedimentary basins in East Greenland between latitudes 71°N and 74°N (Fig. 1) where nine field teams worked for six weeks in July and August supported by a Hughes 500 helicopter. Within the framework of the project, additional hydrocarbon-related field studies were undertaken in 1996 in western North Greenland, and ore-geological studies were carried out in much of North Greenland (Kragh et al., 1997; Stemmerik et al., 1997). The 1996 field work in East Greenland concentrated on integrated structural, sedimentological and biostratigraphical studies of the Upper Permian and Mesozoic successions. Two Ph.D. projects focused on the sedimentology of the Lower Triassic Wordie Creek Formation and the diagenesis of the Middle and Upper Jurassic succession. Post-doctorate studies were carried out on the Mesozoic–Tertiary structural development of the basin and the mineralisation of the Upper Permian Ravnefjeld Formation. Three student projects on Lower Triassic and Middle Jurassic ammonite stratigraphy, Upper Permian sedimentology, and fault-associated mineralisation were also included in the work. The most important new results arising from the 1996 field work are: 1) Re-interpretation of the Upper Permian Schuchert Dal Formation as a lowstand turbidite unit within the Ravnefjeld Formation; 2) Recognition of Middle Jurassic deposits and thick lowermost Cretaceous sandstones on Hold with Hope; 3) Interpretation of a full spectrum of scarp-derived coarse-clastic mass movement deposits interbedded with Cretaceous shales on eastern Traill Ø; 4) The presence of a thick sand-rich Cretaceous turbidite succession on eastern Traill Ø; 5) Re-interpretation of the Mesozoic–Cenozoic fault systems on Traill Ø and Geographical Society Ø.

The Upper Palaeozoic - Mesozoic sequence in the Jameson Land area (figs 1, 2) is well known from numerous studies carried out since GGU initiated mapping of the area in 1968 (e.g. Clemmensen, 1980a, b; Surlyk et al., 1973, 1984, 1986a; Surlyk, 1983, 1987; Heinberg & Birkelund, 1984). Based on these studies, Surlyk et al. (1986b) proposed that a number of Upper Permian - Cretaceous formations have a reservoir potential. Sandstone and limestone samples from these and a few additional formations (fig. 2) have been anaIysed for porosity and air-permeability. The analyses, all performed on surface samples or shallow cores, represent the first numerical approach to the evaluation of reservoir properties in the Jameson Land - Scoresby Land basin, and form a preliminary background for a more detailed reservoir study presently being undertaken by GGU. The analyses were carried out commercially by the Core Analysis Laboratory of the Geological Survey of Denmark (Haslund, 1985; Springer, 1986). Air-permeability, He-porosity and grain density were measured conventionally on uncleaned 1" x 1" plugs after humidity drying.

The background for the Geological Survey of Greenland's (GGU's) hydrocarbon-geological activities was briefly outlined in the Report of Activities for 1989 (Stemmerik et al., 1990a). In that report it was intimated that a shift of emphasis in hydrocarbon-geological activities was under way, not only from onshore to offshore but also from East to West Greenland (Fig. 1). 1990 saw this shift take more concrete form. Thus field work in East Greenland was limited to minor projects that focus on diagenesis and reservoir properties of siliciclastic sediments. All other projects onshore East Greenland have reached or are entering into final report stage

Posidonia Shale

From the 12th to 25th of July outcrops of bituminous shales and limestones at four localities were visited by the authors. Three of the outcrops, at Fleming Fjord opposite Wegener Halvø, at Nathorst Fjord and at Edderfugledal were of Myalina Limestone of the Triassic Solfaldsdal Member. The fourth locality in the Schuchert Flod area near the western edge of the sedimentary basin involved the Upper Permian Posidonia Shale Member. The main purpose of the field work was for Stevens, as the Survey's consultant, to get acquainted with the geology of the main rock types in the field, mainly with respect to environments of deposition and also to discover indications or proofs of the migration of hydrocarbons. Perch-Nielsen being conversant with the geology from previous seasons mapping acted as field guide. Samples were collected for analysis to increase the information already obtained from samples collected by the Survey during previous mapping.

Geology of Greenland Survey Bulletin, 186, 50-59. https://doi.org/10.34194/ggub.v186.5215 _______________ The southern tip of Greenland is underlain by the Palaeoproterozoic Ketilidian orogen (e.g. Chadwick & Garde 1996; Garde et al. 1998a). Field investigations in the summer of 1999 were focused on the structure of migmatites (metatexites) and garnetiferous granites (diatexites) of the Pelite Zone in the coastal region of South-East Greenland between Lindenow Fjord and Kap Farvel (Figs 1, 2). Here, we first address the tectonic evolution in the Pelite Zone in that region and its correlation with that in the Psammite Zone further north. Then, the structure and intrusive relationships of the rapakivi suite in the Pelite Zone are discussed, including particular reference to the interpretation of the controversial outcrop on Qernertoq (Figs 2, 8). Studies of the structure of the north-eastern part of the Julianehåb batholith around Qulleq were continued briefly from 1998 but are not addressed here (Fig. 1; Garde et al. 1999). The field study was keyed to an interpretation of the Ketilidian orogen as a whole, including controls of rates of thermal and tectonic processes in convergent settings. Earlier Survey field work (project SUPRASYD, 1992–1996) had as its principal target an evaluation of the economic potential of the orogen (Nielsen et al. 1993). Ensuing plate-tectonic studies were mainly funded in 1997–1998 by Danish research foundations and in 1999 by the Natural Environment Research Council, UK. The five-week programme in 1999 was seriously disrupted by bad weather, common in this part of Greenland, and our objectives were only just achieved. Telestation Prins Christian Sund was the base for our operations (Fig. 2), which were flown with a small helicopter (Hughes MD-500).

Mantle xenoliths from Tertiary lavas and dykes on Ubekendt Ejland, West Greenland. Geology of Greenland Survey Bulletin, 180, 152-154. https://doi.org/10.34194/ggub.v180.5099 _______________ Mantle xenoliths were found in Tertiary alkaline (basanitic) lavas on Ubekendt Ejland in West Greenland in the mid 1970s by J.G. Larsen. Microprobe analyses of olivine, pyroxene and spinel in two mantle xenoliths, suggested that the xenoliths on Ubekendt Ejland are highly depleted and have high modal olivine contents, and low modal orthopyroxene and clinopyroxene (Larsen 1982). In this respect the mantle xenoliths from Ubekendt Ejland are very similar to the spinel harzburgites from Wiedemann Fjord, in the Tertiary volcanic province of East Greenland (Brooks & Rucklidge 1973; Bernstein et al. 1998). Larsen (1981) also reported dykes containing mantle nodules and a varied suite of cumulates and megacrysts, one of which has subsequently been dated to 34.1 ± 0.2 Ma (Storey et al. 1998) The basalt flow that carries the xenoliths is from what is defined as the Erqua Formation which occurs at the top of the lava succession in western Ubekendt Ejland (Fig. 1; Drever & Game 1948; Larsen 1977a, b). The basalts have not been dated, but are younger than 52.5 Ma, which is the date obtained for the underlying formation (Storey et al. 1998). During July 1997, we spent three weeks collecting xenoliths and prospecting for xenolith-bearing dykes in the Uummannaq district of central West Greenland. The field work resulted in an extensive collection of xenoliths from an alkaline basalt flow described by Larsen (1977a, b), as well as the discovery of a dyke carrying a large number of ultramafic xenoliths of various origins.
