    Nyckelord :avsättningsmiljöer; stratigrafi; Sweden; Scania; Röstånga; Silurian; Ordovician; TAI; Thermal Alteration Index; palynology; sea level changes; stratigraphy; depositional environments; havsnivåförändringar; palynologi; Ordovicium; Silur; Skåne; Sverige.; Earth and Environmental Sciences;

    Sammanfattning : A multiproxy study on sedimentary rocks spanning the Ordovician-Silurian boundary has been performed on material from the Röstånga-1 core, with the aims to improve the biostratigraphical and sedimentological framework and to interpret the depositional environment during this interval in Earth’s history. The sedimentary succession in the Röstånga-1 core is developed in the Scanian Lithofacies Belt and is considered an excellent upper Middle Ordovician-Lower Silurian reference section for southernmost Sweden.

    Sammanfattning : A severe shortage of many, to mankind, valuable elements are to be expected in the near future. Therefor is it of utmost importance to find these deposits and a way to refine the elements with as little negative effect on the environment as possible. One deposit of valuable elements such as U, V, Mo and Sr are the so called alum shale. LÄS MER
