  4. 3. The Ordovician Orthoceratite Limestone and the Blommiga Bladet hardground complex at Horns Udde, Öland

    University essay from Lunds universitet/Geologiska institutionen

    Author : Magnus Eriksson; [2010]
    Keywords : Orthoceratite Limestone; hardground; Lanna; Volkhov; Dapingian; Gastrochaenolites oelandicus; Blommiga Bladet; sea-level; Ortoceratitkalkstenen; hårdbotten; havsnivå; Earth and Environmental Sciences;

    Abstract : Blommiga Bladet, Flowery Sheet in English, is an Early Ordovician (basal Dapingian) hardground complex in the lowermost part of the Orthoceratite Limestone in southern Sweden. It formed in an epicontinental sea, across Baltoscandia and has been described also from Russia as “Steklo”, from Estonia as “Pustakkith” and from deep borings in Poland, thus covering an area exceeding 500,000 km².

  5. 4. Upper Ordovician through lowermost Silurian stratigraphy and facies of the Borenshult-1 core, Östergötland, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Amir Noor; [2010]
    Keywords : Borenshult-1 core; palaeoclimate; upper Ordovician; sea-level; GICE; HICE; Baltoscandia; Earth and Environmental Sciences;

    Abstract : The Ordovician is an important period in the Phanerozoic, with remarkable faunal turnovers, several major carbon isotope excursions, and shifting climate. The strata of this time period not only re-veal these events but also provide useful information about the palaeoclimate and sea-level. READ MORE

  6. 5. Conodont biostratigraphy in Volkhovian sediments from the Mäekalda section, north-central Estonia

    University essay from Lunds universitet/Geologiska institutionen

    Author : Jenny Wickström; [1999]
    Keywords : Conodonts; biostratigraphy; Baltoniodus navis Zone; Paroistodus originalis Zone; Baltoniodus norrlandicus Zone; Toila Formation; Volkhov; Arenig; Ordovician; Mäekalda; Estonia; Earth and Environmental Sciences;

    Abstract : This investigation examines the distribution of conodont elements in the upper Lower Ordovician (Arenig) Volkhov Stage of the Mäekalda section situated in the Tallinn area, north-central Estonia. Slightly more than 36,000 conodont elements from 18 samples were investigated, and the biostratigraphic result was compared to previous works on conodont biostratigraphy from localities in south-central Sweden.
