  1. 1. Petrography of impactites from the Dellen impact structure, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Robert Mroczek; [2023]
    Nyckelord :Dellen; Impact; structure; magnetite; apatite; shock waves; shock-metamorphic; features; Impactite; petrography; scanning electron microscope; SEM; geology; Earth and Environmental Sciences;

    Sammanfattning : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.

  2. 2. Microscopic shock-metamorphic features in crystalline bedrock : a comparison between shocked and unshocked granite from the Siljan impact structure

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Robert Mroczek; [2014]
    Nyckelord :impact structure; Siljan; planar deformation features; Earth and Environmental Sciences;

    Sammanfattning : During the Devonian, 377 Ma ago, the Earth was impacted by a large celestial body, striking ground in the Siljan area in Dalarna, Sweden. The impact created what is today the largest confirmed impact structure in western Europe. Since its formation, the structure has however been heavily eroded, leaving no trace of the original crater.
