Abstract: 

The present paper presents results of stratigraphical, sedimentological and micropalaeontological investigations of an olistolith from the Budoskut area in the Bukk Mts (NW Hungary). The olistolith consists of Norian sub- and peritidal platform carbonates (Budoskut limestone). 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.

During the Early up to the Late Jurassic the host rock was dissected by neptunian dykes. The internal sediment's faunal content reveals that the dykes formed during the (?) Hettangian/Sinemurian and the Toarcian Oxfordian age.

A comparison of the Budoskut limestone neptunian dyke internal sediments with the Bukk parautochthonous and the Szarvasko-Monosbel nappe complex sedimentary columns shows no similarities. Therefore the Budoskut olistolith is interpreted as an exotic body within the Bukk Mts.
