The main factors of the developmental environment of marine source rocks in continental margin basins have their specificality. This realization, in return, has led to the recognition that the developmental environment and pattern of marine source rocks, especially for the source rocks in continental margin basins, are still controversial or poorly understood. Through the analysis of the trace ...

Patterns of plant distribution by palaeoenvironment were examined across the Pennsylvanian-Permian transition in North-Central Texas. Stratigraphically recurrent packages of distinct lithofacies, representing different habitats, contain qualitatively and quantitatively different macrofloras and microfloras. The species pools demonstrate niche conservatism, remaining closely tied to specific hab...

The preservation of rock art in open-air contexts is a global issue controlled by several environmental processes, which are less investigated than the cultural significance engravings and paintings. For that reason, we discuss age, preservation, palaeoenvironmental context petroglyphs discovered on flat, almost vertical face large boulder fallen along western slope Jabal Hammah, rocky hill bor...

Outcrop samples were collected from Dukku area for the purpose of subjecting them to palynological analysis in order determine relative age Gwandu Formation and palaeoenvironment deposition deposit. Field laboratory methods carried out obtain lithological sequence description outcrop. The obtained went through processes acid digestion with hydrochloric acid, hydrofluoric separation macerals by ...

ABSTRACT During the last 60 years, thickness of Grel peatland deposits (Polish Inner Carpathians), was decreased twice: from about 7.4 m in 1962, to 3.9 2019. Pollen analyses peat performed 1962 (Koperowa 1962) and 2019 (this study) showed that have accumulated since Oldest Dryas Stadial up present day. Comparative analysis both palynological profiles carried out, which exhibits a high consiste...

Reconstructing provenance in sandstones can be challenging, especially when the hinterland palaeogeology is unknown due to burial, diagenesis or weathering of original outcrops. As sedimentary processes alter distribution minerals depositional environment, use multiple methods reduces uncertainties, because, together, they account for depositionally-controlled textural and mineralogical re-dist...
