CHAOTIC COMPLEXES IN GORLICE REGION (POLISH OUTER CARPATHIANS)

Abstract. Geological research in Gorlice region has revealed existence of chaotic complexes "block in matrix" type. These chaotic complexes usually were taken for some "flych" members as e.g. variegated shales or Inoceramus beds. The research have also revealed chaotic character of the so called Łużna and Harklowa "peninsulas" and outliers and confirmed Miocene age of embedding matrix. The most frequent types of the chaotic complexes on the area studied are wide tectonic melanges that separate individual tectonic elements. There occur deformed olistostromes of the Miocene age. To explain of the seat of Łużna or Harklowa "penninsulas" and outliers a hypothesis of slumping from active slope or slumping from active fault scar was applied. Zones so called out-of-sequence thrusts associated with broad zones of melanges were also recognised during extensive field work.
