Ami sedimentological model in the Tatra Eocene

Andrzej Kulka

Abstract


The facies distribution in the Tatra Eocene conforms well the Ami model. The similarities are demonstrated by faunal content and petrographic composition. The relation between the size and shape of nummulite and discocycline tests and energy of depositional environment has been confirmed. The interpretation of the vertical sequence of nummulite faunas according to the Ami model. modifies the stratigraphic evaluations of the index forms of the hemeras I, II and III of F. Bieda. The species Nummulites brongniarti, N. perforatus and N. millecaput lived simultaneously and their consecutive appearance in the sections reflects the lateral, transgressive facies migration.
