   Nyckelord :Sweden; Kulla Gunnarstorp; jurassic; wrinkle structures; microbially induced sedimentary structures; skrynklestrukturer; mikrobiellt inducerade sedimentstrukturer; jura; Sverige; Earth and Environmental Sciences;

   Sammanfattning : Wrinkle structures, a type of microbially induced sedimentary structures (MISS) were found in Jurassic tidally deposited heterolites of Kulla Gunnarstorp, southern Sweden. Wrinkle structures are characterizeded by minute, commonly elongate crinkles on the upper bedding planes of fine grained arenites. LÄS MER
