objective: the asmari formation is characterised by alternation thick carbonate and marl sequence of the oligocene- miocene in the zagros basin, southwest of iran that were deposited on the shelf of eastern paratethys. methods: this formation is exposed at tang-e-khoshk in the fars subcoastal zone with a thickness of 286 m comprising alternation of medium and thick to massive bedded carbonates,...

The middle Miocene foraminifera and ostracod record of the Central Paratethys usually reflects stable normal marine epositional environments for Badenian more patchy, less restricted Sarmatian. A 17 m thick outcrop at Pécs-Danitzpuszta, Mecsek Mts, SW Hungary exposed an upper to Pannonian succession where foraminifers ostracods document significant environmental changes. basal layers section co...

A new species of the genus Niphargus Schiödte, 1849 (Crustacea: Amphipoda: Niphargidae), co-existing with other stygobiotic amphipods, Diasynurella kiwi Marin and Palatov, 2023 Pontonyx donensis (Martynov, 1919) (Crangonyctidae), is described from a small spring on shore Kiziterinka River in Rostov-on-Don City mouth Don River. Two three studied spring, D. discovered Niphargus, belong to microcr...

Eocene and Lower Oligocene rocks are potential source for crude oil accumulations in the Hungarian Palaeogene Basin. To enhance understanding of hydrocarbon system, this study (i) assesses petroleum formations, (ii) characterises rock facies accumulated oils, (iii) provides an oil-to-source correlation. Rock-Eval data samples from three boreholes (W–1, W–9 W–12) show that most formations mature...
