    Węglowe osady miocenu Kępy Swarzewskiej na wybrzeżu bałtyckim
    (Wydawnictwa AGH, 2007) Wagner, Marian
    Kępa Swarzewska is situated in northern Poland, close to the Gdańsk Bay in the Kaszuby coastal zone. Within hill-side, the Miocen coal-bearing sediments occur under the Pleistocene deposits. The observations of the cliff walls have provided the basis of distinguishing two coaly complexes: Lower Miocene lignite grup (II), and Middle Miocene lignite group (I), comparable to the respective units of the Polish Lowland. The distinguished sandy complexes contain three lignite seams with a thickness of 0.7-3.1 m. The lignite are included into detritic lithotypes, low rank of middle gelified variety of humic coal. Atrinite is the major microcomponent of this coal. The contribution of the macerals of the liptinite and inertinite groups is subordinate. Low rank and humic character is confirmed by such the results of chemical and technological analyses. Sedimentological diagrams method was used in order to estimate the sequence of organic facies in the paleo peatbogs (marsh, swamp). In the north part of the area of the Kępa Swarzewska a sequence of sedimentation in the anostomosing fluvial system have been found.
