1. 11. Early to early Middle Ordovician conodont biostratigraphy of the Tamsalu drill core, central Estonia

   University essay from Lunds universitet/Geologiska institutionen

   Author : Lisa Sjöstrand; [2003]
   Keywords : Ordovician; Latorpian; Volkhovian; Kundan; Aserian; conodonts; biostratigraphy; Parapaltodus n. sp. A; Texania sp. A; Tamsalu; Estonia; Earth and Environmental Sciences;

   Abstract : This investigation examines the distribution of conodont elements in the Early to early Middle Ordovician Latorpian, Volkhovian, Kundan and Aserian stages of the Tamsalu drill core in central Estonia. Slightly more than 24, 600 conodont elements from 17 samples were examined, and the biostratigraphic results were compared to previous works on conodont biostratigraphy from localities in Estonia, Russia and Öland, Sweden.

3. 12. Diagenetic and petrophysical properties of deeply versus moderately buried Cambrian sandstones of the Caledonian foreland, southern Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Christine Karlsson; [2001]
   Keywords : diagenesis; petrography; sandstone; burial; Lower Cambrian; Caledonian foreland; Västergötland; Skåne; Sweden; Earth and Environmental Sciences;

   Abstract : The Lower Cambrian strata of the Caledonian foreland of southern Sweden consist mainly of quartzitic sandstones with thicknesses of approximately 35 meters in Västergötland and 120 meters in Skåne. In the distal, moderately buried western members of the File Haidar Formation of Västergötand porosity and permeability was higher than in the proximal deeply buried units of the Hardeberga Formation of Skåne.

   Abstract : Upper Cambrian strata are well exposed in an old quarry at Kakeled on south-western Kinnekulle, south-central Sweden. The exposures consist of finely laminated alum shale with lenses and beds of dark grey limestone (stinkstone or orsten), and a few thin layers of sandstone. A 6. READ MORE
