  1. 1. Investigation of Thermal Maturity of  Organic Matter at the Cambro Ordovician Transition in the Zagros Basin, Iran

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Niall Gibbons; [2021]
    Keywords : acritarchs; thermal maturity; Zagros Basin; hydrocarbons; source rocks; paleoenvironment;

    Abstract : The thermal maturity of sediments from the upper Cambrian to lower Ordovician Mila and Ilbeyk  formations in the Zagros Basin in southwestern Iran is evaluated in this thesis. A number of low-cost,  fast, optical evaluation methods are utilised to assess their effectiveness for providing accurate, well  constrained thermal maturity results. READ MORE

  3. 2. Stratigraphy and pyrite geochemistry of the Lower–Upper Ordovician in the Lerhamn and Fågelsång-3 drill cores, Scania, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Fisnik Balija; [2018]
    Keywords : Ordovician; shale; drill cores; arsenic; pyrite; heavy metals; Lerhamn; Fågelsång; Scania; Sweden.; Earth and Environmental Sciences;

    Abstract : Arsenik är ett mycket giftigt ämne som finns i berg, mark och grundvatten, och är känt för att orsaka allvarliga hälsoeffekter. Neurologiska skador hos människan inträffar vid koncentrationer så låga som 100 μg/L, medan 1–3 mg/kg kroppsvikt As är en dödlig dos. READ MORE

  4. 3. Sedimentology and carbon isotope stratigraphy of Lower–Middle Ordovician successions of Slemmestad (Oslo-Asker, Norway) and Brunflo (Jämtland, Sweden)

  5. 4. 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

  6. 5. Prediction of the degree of thermal breakdown of limestone : a case study of the Upper Ordovician Boda Limestone, Siljan district, central Sweden

    University essay from Lunds universitet/Geologiska institutionen
