geusb: A Pathfinder

This is a computer-generated pathfinder created against the Distant Reader study called geusb.

Each Distant Reader study carrel is composed of many individual items. Each item is bibliographically described with author, title, date, summary, and keyword values. Below is a list of the items' most signficant keywords as well as lists of the items themselves. Purpusing the content of this pathfinder provides the student, researcher, or scholar with one way to get their heads around the scope of the carrel. The keywords include:

Denmark; Data; Formation; North; Sea; East; Ice; Jurassic; Basin; West; Area; Danish; Rocks; Marine; Bulletin; Zone; Geus; Survey; Surface; Water; Sand; Samples; Age; Sandstones; Fault; Chalk; Groundwater; Core; Facies; Unit; Group; Gas; Sediments; Log; Oil; Complex; Nielsen; Reservoir; Lake; Region; Temperature; Quartz; Areas; Zircon; Sediment; Till; Basalt; Storage; Intrusion; Gold; Energy; Time; Project; Archaean; Database; Rock; Material; Disko; Analysis; Stations; Wave; Klint; Soil; Earthquakes; Inclusions; Edulis; Garde; Pge; Dimension

Depending on how this pathfinder was created, many of the bibliographic sections will include elaborations on the meaning(s) of the given keywords. These elaborations were generated by feeding the items' summaries to a large langauge model and asking the model to address the question, "What is X?", where "X" is the keyword. The result will be a few sentences of elaboration. Be forewarned. The elaborations are often plausible, but they should not be take as truth. Instead, they should be taken as points for consideration.

• Burial depth and post-Early Cretaceous uplift of Lower–Middle Jurassic strata in the Fennoscandian Border Zone based on organic maturity by Petersen, Henrik I; Nielsen, Lars H; Bidstrup, Torben; Thomsen, Erik (2003) - This relationship can then be used to estimate the maximum burial depths and later uplift of Jurassic coal seams in the Fennoscandian Border Zone. In order to avoid complications due to the late Early Jurassic – Middle Jurassic uplift of the Ring- købing–Fyn High and the southern parts of the basin, the majority of the data used for construction of the curve comes from well-sections that experienced continued subsidence or only limited uplift and erosion during this phase (Nielsen 1995).

• Ablation observations for 2008–2011 from the Programme for Monitoring of the Greenland Ice Sheet (PROMICE) by Fausto, Robert S; van As, Dirk (2012) - By measuring on a (sub-)daily timescale, the pressure transducer assembly is well suited to monitor ice ablation in remote regions, with clear advantages over other well-estab- lished methods. The geographical distribution and annual net ablation records in Table 2 show that for all station pairs, the lower stations measure larger ablation totals than the upper ones, because the temperature decreases with elevation and the seasonal averaged surface albedo decreases towards the ice margin.

• Gold-hosting supracrustal rocks on Storø, southern West Greenland: lithologies and geological environment by Knudsen, Christian; van Gool, Jeroen A M; Østergaard, Claus; Hollis, Julie A; Rink-Jørgensen, Matilde; Persson, Mac; Szilas, Kristoffer (2007) - The prospect is at present being explored by the Greenlandic mining company NunaMinerals A/S. Amphibolites likely to be derived from basaltic volcanic rocks dominate, and ultrabasic to intermediate rocks are also inter- preted to be derived from volcanic rocks. The next sequence of supracrustal rocks was formed at c. 3.1–3.07 Ga, intruded by tonalites at c. 3.07–3.05 Ga, and deformed and metamorphosed at c. 2.98 Ga.

• Two tectonically significant enclaves in the Nordre Strømfjord shear zone at Ataneq, central West Greenland by Glassley, William E; Korstgård, John A; Sørensen, Kai (2007) - High-pressure enclave On the north side of inner Ataneq fjord an approximately 1.2 m wide and 4 m long lens of ultramafic rock occurs within strongly foliated garnet-sillimanite gneisses and schists, and garnet-bearing calc-silicate rock (Fig. 2). The occurrence of garnet + olivine in ultramafic rocks and the occurrence of eclogite minerals in mafic compositions are the diagnostic mineral assemblages for HP metamorphism. Keywords: fig; garnet; greenland; orthopyroxene; rock; ultramafic

• Characterisation of incinerator bottom ash from a Danish waste-to-energy plant: a step towards closing the material cycle by Clausen, Rune J. ; Kalvig, Per ; Nedenskov, Jonas (2019) - Assuming the distribution of the five material groups measured for Amager Bakke IBA is representative of IBA in Denmark and the EU, we can apply these class distributions to the national and EU-level data (Table 1). But this is neither possible nor meaningful for IBA material for the following reasons: 1. Keywords: amager; bakke; fragments; iba; material; metal; non; waste

Geological Survey of Denmark and Greenland Bulletin 35, 79–82. Open access: www.geus.dk/publications/bull A marked change in crustal thickness is seen at the defor- mation boundary between the undisturbed Archaean core in the south and reworked Archaean gneiss in the foreland of the Nagssugtoqidian orogen in West Greenland. Keywords: deformation; greenland; profile; stations

• Acoustic events on a small seismological network – shock waves from thunder and fireballs by Voss, Peter H.; Dahl-Jensen, Trine; Larsen, Tine B. (2015) - But from time to time other sources than earthquakes generate seismic signals that are detected at the stations. Here we show that both meteoroids and thun- der have generated seismic signals with high signal-to-noise ratios at some of GEUS’ seismic stations (Fig. 1). Keywords: fig; signals; station; wave

• Cliff collapse at Stevns Klint, south-east Denmark by Schack Pedersen, Stig A.; Damholt, Tove (2012) - Types of cliff collapses at Stevns Klint The largest type of cliff collapse at Stevns Klint can be called cliff slides (Fig. 3). The general conditions of cliff erosion are described and the rockfall dynamics for the various types of cliff collapse are characterised. Keywords: cliff; collapse; fig; klint; overhang; stevns

• Pesticide leaching in Danish groundwater: identification of vulnerable areas by Nygaard, Erik; Ernstsen, Vibeke; Jacobsen, Carsten S; Jacobsen, Ole H; Juhler, René K; van der Keur, Peter; Olesen, Svend E; Rasmussen, Jim; Rosenberg, Per; Vosgerau, Henrik (2004) - Since mapping is the key to the identification of vulnera- ble areas, emphasis has been placed on generating a set of data based on soil parameters that can be easily and relatively inex- pensively obtained. The number of soil parameters required to obtain this cor- relation vary according to pesticide type. Keywords: fig; leaching; parameters; pesticides; soil; sorption
• Direct analysis of microbial populations in soil and freshwater aquifers using nucleic acid based techniques by Jacobsen, Carsten S; de Lipthay, Julia R; Bender, Mikkel; Fredslund, Line; Johnsen, Anders R; Johnsen, Kaare (2004) - This was further demonstrated by greatly increased populations of pesticide degraders inside the pesti- cide plume, both when enumerated by cultivation, and when quantified by the number of pesticide genes (tfdABC) detected by PCR methods (Fig. Microbial changes in aquifers contaminated with phenoxyalcanoic acid herbicides This section focuses on specific genes of interest rather than on organisms. Keywords: acid; dna; fig; genes; methods; mrna; pcr; soil; techniques
• Steam treatment of contaminated groundwater aquifers – development of pathogenic micro-organisms in soil by Jacobsen, Carsten Suhr; Elmholt, Susanne; Bagge Jensen, Carsten; Bach Jakobsen, Pia; Bender, Mikkel (2005) - A few results from the literature indicate that the micro- bial activity increases in steam treated soil (Richardson et al. 2002), probably due to microbial degradation of the soil con- taminants in combination with microbial utilisation of heat- killed organisms. Such high tempera- tures do not occur naturally at the site, and soil micro-orga- nisms originating from this site are not expected to be able to grow at such high temperatures. Keywords: heat; micro; organisms; soil; steam; treatment
