  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
