摘要

The present paper presents results of stratigraphical, sedimentological and micropalaeontological investigations of an olistolith from the Büdöskút area in the Bükk Mts (NW Hungary). The olistolith consists of Norian sub- and peritidal platform carbonates (Büdöskút lime-stone). During early diagenesis dissolution cavities originated which where filled by ostracodal mudstones. Other cavities first were wallpapered by evinospongial crusts and later filled either by ostracodal mudstones or by brick-red haematitic material (weathered bauxite). The evinospongial crusts show stromatolite-like structures and their forming therefore is supposed to be organically (microbially) induced.
