The geochemical characteristics of the Menilite Formation in the Czech Carpathians: A short review

Popis výsledku v původním jazyce

The Paratethys area contains a significant number of petroleum provinces. Most of the accumulations within the Carpathians are sourced by the Oligocene organic-rich Menilite Formation and its equivalents. The vertical variations in lithology within the formation reflect different depositional environment which strongly influences the source rock potential. The Menilite Formation has mostly “good” to “very good” source rock potential based on the Rock-Eval and TOC data, respectively. The Chert Member represents the most prolific member and reaches the HI up to 725 mg HC/g TOC. Significantly lower source rock potential was evaluated within the Šitbořice and partly Subchert members. The organic matter within the Menilite Formation is based on the organic petrography observations predominantly composed by the kerogen type I, while the kerogen type III macerals are typically very rare. The Rock-Eval interpretations indicating presence of kerogen type II and III were inaccurate due to higher amount of non-pyrolyzable organic carbon portion which underestimated the HI.
