Table 2 STRATIGRAPHY OF THE STUDIED FORMATIONS MIOCENE OLIGOCENE EOCENE en S fti O o c 2 I I The Tard Oay — The Tard Clay is dark gray œloured, sometimes-dark brown clayey silt with low carbonate content (10 %). The formation is maximum 100 m thick. Its lower part is built up of alternating fine-laminated pelites. The whole upper part consists of an alternation of black and white laminae with monospecific nannofloras in the white laminae (B.-BEKE 1977; NAGYMAROSY 1983). The high organic content and 2-7 % pyrite are rcxi-building constituents. The organic content originates from autochtonous, marine sapropelic matter (VETŐ 1987). South of Budapest, VÀRGA (1982) recognised graded limestone intercalations from several mm to 10cm thickness in the lower part of the formation. From these graded laminae, Nummuliles fabianii and Ghaprnannma gassinensis were recorded The most common megafossils of the fonnation are plant remains and fish scales. Until the sixties, the Tard Clay was thought to be socalled "forarniniferafree zone" (MÁJZON 1966). Subsequent investigations resulted in a relatively rich fauna (molluscs, large sized ostracodes, foramiriifera)
