“…1). The basin represents a deep intra-cratonic rift with up to 22 km of sediments spanning the mid-Devonian-Cenozoic and is characterised by a WNW-ESE trending axis (Lungershausen 1942;Stovba et al 2003;Sachsenhofer et al 2012). The sedimentary successions within the basin are poorly exposed, and knowledge about the sedimentary evolution is derived mainly from sub-surface data.…”

A palynological and sedimentological study of an outcrop succession adjacent to the village of Kamyanka within the Kharkiv region of northeast Ukraine was carried out. The successions occur within the Dnieper-Donets Basin, which hosts vast successions (> 20 km) of post midDevonian strata and is one of the main hydrocarbonproducing basins in Europe. Middle Jurassic sandstones, siltstones and claystones represent the sedimentary successions at the Kamyanska locality. Few palynological studies have been performed on the Jurassic of Ukraine and even fewer presented in the international literature. Thirty spore taxa and 21 pollen taxa were identified, together with taxa kept in open nomenclature (e.g. bisaccate pollen). Two palynological assemblages were identified within the Kamyanska succession (assemblages A and B) dated as Bathonian. Assemblage A is dominated by the fern spores (Cyathidites and Osmundacidites) and gymnosperm pollen produced by Cupressaceae (Perinopollenites elatoides), ginkgophytes/Cycadales/ Bennettitales (monosulcates) and Cheirolepidiaceae (Classopollis). Assemblage B differs in also comprising high abundances of Gleicheniidites and higher percentages of Pinuspollenites and Araucariacites compared to assemblage A. Another difference between the two units is the high relative abundance of seed fern pollen (Alisporites) in the upper part of assemblage B. The thermal alteration index (TAI) of the palynomorphs is estimated to range from 3 to 3.5, indicating a burial depth corresponding to the mature main phase of liquid petroleum and, to some extent, gas generation. Comparisons between the miospore and macrofloral assemblages show that the palynoflora and macroflora are strongly similar at broad taxonomic levels. Importantly, the miospore assemblages described here compare well with European Middle Jurassic assemblages indicating limited provincialism, with similar vegetation extending from eastern Ukraine and across most of Western Europe.Keywords Mesozoic .

Dnieper-Donets Basin ІntroductionThe Jurassic is an interesting period in the Earth's history as it saw the rise to ecological dominance of the dinosaurs, the evolution of birds, extant sub-classes of mammals, the fragmentation of Pangea and two major flood basalt events, both associated with massive biotic change. This took place in a context of generally elevated CO 2 and muted latitudinal temperature gradients; i.e. temperature differences between the tropics and the polar regions were less extreme compared to the present (Steinthorsdottir and Vajda 2015; Slater et al. 2018a, this issue). The poles were ice-free, and the vegetation was characterised by little provincialism (Vajda and WigforssLange 2009). However, in order to compare and contrast the vegetation between different regions through the palynoflora,

“…Rudov Beds) together with Serpukhovian to Moscovian coaly layers are potential source rock horizons. Oil window maturity (~0.65 % Rr; random vitrinite reflectance in oil) in the north-western part of the basin is reached at around 3,500 m depth, but at shallower depth in the inverted SE part of the DDB [5,15,16]. Hydrocarbon generation occurred predominantly during Permian deep burial, according to previous basin modelling studies [16].…”

Abstract. Porosity and permeability are essential parameters for reservoir rocks. Techniques developed for conventional reservoir rocks characterized by large pores, cannot be applied to study gas shales. Therefore, high resolution techniques are increasingly used to determine reservoir quality of shale gas plays. Within the frame of the recent study, Upper Visean black shales ("Rudov Beds") from the Dniepr-Donets-Basin (DDB, Ukraine) were characterized by X-ray diffraction, conventional SEM imaging and FIB/BIB-SEM.According to SEM and FIB/BIB-SEM data, nanopores are not abundant in primary macerals (e.g., vitrinite) even in overmature rocks, whereas they develop within secondary organic matter (bitumen) formed mainly at gas window maturity. Frequently occurring sub-micrometre porosity, probably related to gas generation from bituminous organic matter, was detected within mudstones at a vitrinite reflectance > 2.0 % Rr. However, such pores have also been detected occasionally in solid bitumen at oil window maturity (0.9 % Rr). Authigenic nanoscale clay minerals and calcite occur within pyrobitumen at gas window maturity.Furthermore, Rudov Beds can be subdivided into mineralogical facies zones by SEM imaging and X-ray diffraction. A basin-centred, brittle siliceous facies is most likely caused by increased contribution from deeper water radiolaria and is separated from a marginal clayey and carbonate-rich facies.

“…Many scholars have found that coal and gas outbursts are related to geologic tectonism during their investigation of sites where outbursts occurred (Airey, 1968;Cheng et al, 2013;Sachsenhofer et al, 2012;Zhang et al, 2016). Not all tectonic coal will result in coal and gas outbursts; however, tectonic coal was often found in these sites.…”
