Kiscell, Budapest (Oligocene of Hungary)

Where: Hungary (47.5° N, 19.0° E: paleocoordinates 45.1° N, 17.5° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Kiscell Clay Formation, Oligocene (33.9 - 23.0 Ma)

• Kiscell clay spans late Rupelian-early Chattian interval.

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; lithified, bioturbated, gray, calcareous claystone

• A transtensional origin was generally proposed for the Paleogene Basin of Hungary, assuming an origin analogous to that of the overlying Neogene Pannonian Basin. We suggest an alternative geodynamic scenario for the development of the Paleogene basin complex, as we think that the observations are better understood in terms of a retroarc foredeep basin model. According to this, a flexural basin developed south of the backthrust inner West Carpathian units. (Tari et al. 1993)
• The Kiscell Clay consists of grey calcareous clay and clayey marl, which is not stratified or laminated but well bioturbated
