The Bathonian Ore-Bearing Clay Formation, outcropping in the Gnaszyn open-pit mine at Częstochowa (Poland), includes several horizons of abundant iron carbonate concretions . cores concretionary bodies commonly contain organic matter (OM), dominated by fragments wood. These particles usually display well-preserved primary structures and occur rarely as more deformed and/or completely degraded f...

Lithofacies are the fundamental geological units for shale oil and gas exploration development, soluble organic matter (SOM) is most similar to crude in composition. Both aspects attract our attention interpretation of SOM different lithofacies, which can provide direct evidence predict “sweet spots”. Here, twenty-five samples were collected from Eocene Shahejie Formation Dongying Sag subjected...

The Sarliève marsh in the Limagne plain, in the heart of the French Massif Central, functioned as an endorheic lake during the Late Glacial and the Early and Middle Holocene. During the Late Boreal and the Atlantic it experienced drastic lowering of the water level as a result of dry and warm climatic episodes. Then, pre-evaporitic conditions triggered the deposition of sediment rich in organic...

Diatomites are sedimentary rocks rich in siliceous algae, mainly diatoms, and evident Greece Neogene successions. Despite their significance worldwide potential as source for hydrocarbons, little is known about them the wider area of Greece, limited biostratigraphic characteristics industrial use. This study assesses first time diatomites Western Crete focuses on rock quality hydrocarbon genera...

Abstract Generative potential and thermal maturity for Upper Palaeozoic source rocks from the south-eastern edge of Precaspian Basin were determined using Rock–Eval. A high hydrocarbon rock generative degree Lower Permian, Mid-Carboniferous strata have been revealed based on 39 samples. TOC values 0.4–5.5% obtained mature rocks. Integrated geochemical analysis Rock–Eval studies combined with 1D...
