  1. 11. Stratigraphy and facies of Middle Silurian epicontinental carbonate platform deposits of Gotland, Sweden

    Författare :Mikael Calner; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysisk geografi; Geologi; Geology; physical geography;

    Sammanfattning : The Silurian foreland of Scandinavia included a vast epicontinental carbonate platform system of which the island of Gotland (Sweden) is an erosional remnant. This thesis treats the Late Wenlock succession (Cyrtograptus lundgreni, Pristiograptus dubius parvus, Gothograptus nassa, Colonograptus(?) praedeubeli, and the Co(?) deubeli zones), and emphasises the sedimentology and biostratigraphy of these deposits.

    Sammanfattning : Combining petrological and geochronological data we were able to show that rocks in south Naxos completed a full blueschist-/greenschist-facies metamorphic loop in about 10 Myr, distinctly faster than hitherto believed. We show that the high-pressure rocks reached peak pressure (16.3±0.9 kbar - 619 ±32°C) between 40. LÄS MER

  7. 15. Volcanology of the paleoproterozoic Maurliden area and its four unusual massive sulphide deposits, Skellefteå district, Sweden

    Författare :Cecilia Montelius; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : The Skellefte district is one of three major ore provinces in Sweden and contains more than 85 Zn-Cu-Au-Ag massive sulphide deposits. The Maurliden area is situated in the central part of the district and is a subaqueous volcanic dominated area with four Zn-Pb-Cu-Au-Ag sulphide deposits. LÄS MER
