  1. 16. Seveskollorna i nordöstra Kebnekaise, Kaledoniderna : metabasiter, graniter och ögongnejser

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Anders Lundgren; [2002]
    Nyckelord :geografi; geologi; seveskollor; Kebnekaise; Kaledoniderna; metabasit; granit; ögongnejs; Earth and Environmental Sciences;

    Sammanfattning : The Seve Nappe Complex in the Kebnekaise Mts. is dominated by metabasites (Kebne Dyke Complex) and mylonitic gneisses. This study describes the tectonostratigraphy in two key areas (Nallo and Mårma) and investigates the origin of a granitic gneiss and two varieties of augen gneiss. LÄS MER

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

    Magister-uppsats, Lunds universitet/Geologiska institutionen

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

    Sammanfattning : 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.

  4. 18. Sierggavággeskollans strukturgeologiska utveckling : nyckeln till Sareks berggrundsgeologi

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Tobias Hermansson; [2001]
    Nyckelord :geografi. geologi; strukturgeologi; Sierggavággeskollan; Sarek; berggrundsgeologi; Earth and Environmental Sciences;

    Sammanfattning : The Seve Nappe Complex (SNC) in the northern part of the Sarek Mountains, in NW Sweden, is characterized by large metamorphic contrasts between the individual thrust sheets. Eclogite facies and lower greenschist facies rocks are interleaved in a pattern that cannot be explained by normal in-sequence thrusting. LÄS MER

  5. 19. Tektonostratigrafi och deformationsrelaterad metamorfos i norra Kebnekaisefjällen, Skandinaviska Kaledoniderna

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Daniel Boman; [2001]
    Nyckelord :geografi; geologi; tektonostratigrafi; Kaledoniderna; Kebnekaisefjällen; metamorfos; deformation; Earth and Environmental Sciences;

    Sammanfattning : The tectonostratigraphic units in northern Kebnekaise Mountains mainly belong to the Seve Nappe Complex. These rocks were originally formed at the continental margin of Baltica in Late-Proterozoic time and mainly consist of amphibolite, granitic gneisses and metasediments. The metamorphic grade is usually amphibolite facies. LÄS MER

  7. 20. En paleomagnetisk detaljstudie av Sarekgångsvärmen

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Erik Eneroth; [2000]
    Nyckelord :palaeomagnetism; Seve Nappe Complex; northern Swedish Caledonides; extensional environments; continent-ocean transition; dolerite; sheeted dyke complex; Earth and Environmental Sciences;

    Sammanfattning : Populärvetenskaplig sammanfattning: Vid Favorithällen i Sareks Nationalpark i Norra Lappland finns bergarter som bildades på havets botten för ca 600 miljoner år sedan (i slutet av prekambrium). I det skedet var berggrunden på väg att dras isär i samband med att en ny ocean bildades. Tjocka sedimentpackar med bl.a. LÄS MER
