From the vicinity of Ecseg (as well as from the neighboring Kozárd) an extremely rich mollusk and ancestral botanical material was found from the Sarmatian limestone sandstones. Of the latter, Boda J. described Acicularia conica from here. The Fóti Formation lies in the area of the Garábi Slír Formation, which has an average thickness of 220-230 m, and its formations are mostly thick-bedded and well stratified. Its rock material is gray, greenish-gray, glittery siltstone, fine-sand clay, mollusc clay marl and fine-grained clayey sand, formed by the coalescence of near-shore terrestrial sediment and fine-grained marine sediment transported into the deeper and shallower seas of the Carpathian period; thus, there is a significant proportion of clayey formations that form a good slip path for deep-nesting landslides, i.e., swellings, which swell well under the influence of water. The two types of rock that make up the area behave differently when slipping. Looser sediments spread along the slope, while harder rocks below them move along the slope. These scattered harder rock blocks form the higher, slower-decaying parts of the surface, the hups, while mostly behind these hups the burrows, depressions without runoff, that house the lakes,(Cholnoky J. 1926).
