  1. 16. Petrophysical and GeophysicalAnalysis of Ordovician Limestone Mounds for the Purpose of Hydrocarbon Reservoir Exploration : Petrofysisk och geofysisk analys av Ordoviciska kalkstensstrukturer för hydrokarbonprospektering

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Felix Söderberg; [2015]
    Keywords : Gotland; hydrocarbons; Ordovicium; mounds; reefal structures; Hydrokarbon; revstruktur; slamhög; ordovicium; Gotland;

    Abstract : Gripen Oil & Gas have extended their prospecting license on Gotland to the north end of the island to search for potential hydrocarbon reservoirs. Earlier prospecting has shown that limestone mound structures from Ordovicium have high potential as hydrocarbon reservoirs due to their antiformal shape and the petrophysical properties of the limestone.

  3. 17. A palynological study across the Ordovician Kinnekulle bentonite, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Johan Nordas; [2015]
    Keywords : Acritarch; bentonite; Ordovician; Borenshult-1; Sweden; Kinnekulle; Earth and Environmental Sciences;

    Abstract : A palynological analysis across the Ordovician (Sandbian) Kinnekulle bentonites in south Central Sweden has been performed. The sedimentary successions were recovered from the Borenshult -1 drillcore in the Motala area, south central Sweden. The lithology is dominated by mudstones and two thick bentonite beds. READ MORE

  4. 18. Chrome spinel grains from the Komstad Limestone Formation, Killeröd, southern Sweden : a high-resolution study of an increased meteorite flux in the Middle Ordovician

    University essay from Lunds universitet/Geologiska institutionen

    Author : Ellinor Martin; [2014]
    Keywords : chrome spinel; fossil meteorites; Komstad Limestone; winonaites; Middle Ordovician; carbonate sedimentology; Earth and Environmental Sciences;

    Abstract : I mellersta ordovicium var inflödet av kosmiskt material till jorden högre än idag, i sviter-na efter uppbrytningen av den L-kondritiska asteroidkroppen i asteroidbältet mellan Mars och Jupiter, vilket beri-kade den forna havsbottnen med meteoriter och kosmiskt damm. Komstadformationen i Killeröd, Skåne, innehåller ett lager särskilt rikt på L-kondritiska kromitkorn vilket indikerar en hög grad av kondensation. READ MORE

  5. 19. Microscopic echinoderm remains from the Darriwilian (Middle Ordovician) of Västergötland, Sweden - faunal composition and applicability as environmental proxies

    University essay from Lunds universitet/Geologiska institutionen

    Abstract : Mikroskopiska echinodermfossil har undersökts ur prover från täljstensintervallet och intillig-gande delar av ’lanna’- och ’holenkalkstenen’ i Hällekis stenbrott, Västergötland. Den undersökta sektionen är från översta volkhov och mellersta kunda, darriwilian (mellanordovicium). READ MORE

  6. 20. Pressure-Temperature Estimates on the Tjeliken Eclogite from Northern Jämtland, Swedish Caledonides

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Barbro Andersson; [2013]
    Keywords : ;

    Abstract : Eclogites are important in order to understand orogenic processes, since their presence indicates high-pressure metamorphism. In northern Jämtland, Swedish Caledonides, eclogites have been found at several places in the Seve Nappe Complex (SNC). The mountain Tjeliken in the Lower Seve Nappe is one of them. READ MORE
