Sedimentary geology of the middle Carboniferous of the Donbas region (Dniepr-Donets basin, Ukraine)
The Paleozoic Dniepr-Donets Basin in Belarus, Ukraine, and Russia forms a major hydrocarbon province. Although well- and seismic data have established a 20 km thick stratigraphy, field-studies of its sediments are scarce. The inverted Donbas segment (Ukraine) exposes the middle Carboniferous part of the basin's stratigraphy. Here, we provide detailed sedimentological data from 13 sections that ...
متن کاملA Carboniferous insect gall: insight into early ecologic history of the Holometabola.
Although the prevalence or even occurrence of insect herbivory during the Late Carboniferous (Pennsylvanian) has been questioned, we present the earliest-known ecologic evidence showing that by Late Pennsylvanian times (302 million years ago) a larva of the Holometabola was galling the internal tissue of Psaronius tree-fern fronds. Several diagnostic cellular and histological features of these ...
متن کاملDepositional Environment and Sequence Stratigraphy of the Oligocene-Miocene Deposits North and East of Dehdasht, Izeh Zone, Zagros Basin, Iran
In this study, four well-exposed outcrops of the Asmari Fm in the southeastern part of the Izeh Zone of the Zagros Mountains were measured and sampled. In this region, the Asmari Fm is Oligocene to Early Miocene in age as determined by large benthic foraminifera. Based on depositional geometries, biogenic contents and lateral and vertical variations of facies, three depositional models are prop...
متن کاملDepositional History and Sequence Stratigraphy of the Tirgan Formation (Barremian – Aptian) in the Zavin section, NE Iran
The Tirgan Formation (Barremian – Aptian) is exposed in the Kopet Dagh in northeast Iran. One stratigraphic section in Zavin was measured with a thickness of 110 meters. This Formation in section consists of three parts (including lower carbonate, limy shale – marl and upper carbonate rocks). Based on the study of 94 thin sections, 10 carbonate and 2 siliciclastic lithofacies have been identifi...
متن کاملDispersed cuticles and conducting tissue of Sphenophyllum BRONGNIART from the Westphalian D of Kalinovo , Donets Basin , Ukraine
Upper Westphalian coals are usually rich in organic-matter of different plant taxa, including gymnosperms. The assemblage from Kalinovo (Eastern Ukraine) is exceptional in being dominated by Sphenophyllum, both cuticles and conducting tissues. Sphenophyllum cuticles are easily distinguished by their parallel oriented cells with sinuous anticlinal walls, and paracytic stomata on the abaxial cuti...
