In this study, we propose a predictive model for maceral discrimination based on Raman spectroscopic analyses of dispersed organic matter. micro-spectroscopy was coupled with optical and Rock-Eval pyrolysis set seven samples collected from Mesozoic Cenozoic successions the Outer sector Carpathian fold thrust belt. Organic petrography evidence type II/III kerogen complex organofacies composed by...

Even being the more studied of interior basins Northeast Brazil, Araripe Basin still lacks research in organic geochemistry designed to support interpretations depositional systems and conditions formation. This work aims investigate behavior evaporites shales from Santana Group (Lower Cretaceous), as well discuss their role evolution its systems. A total 23 samples, 17 six evaporites, were col...

The paper discusses the issues of interaction organic matter and siliceous-carbonate mineral matrix in unconventional reservoirs Upper Devonian Domanik Formation Kama Depression Volga-Ural Basin. is composed organic-rich low-permeability rocks. Lithological geochemical peculiarities rocks were studied using light microscopy, X-ray diffraction analysis (XRD), scanning electronic microscopy (SEM)...

Abstract A comparative analysis on source rock properties has been carried out the Miocene-Pliocene formations as well Quaternary terrace deposits using Rock–Eval pyrolysis results and organic petrography some biomarkers results. Samples were obtained from outcrops of deposits, Pliocene-aged Liang Formation together with Miocene Miri Setap Shale in Brunei-Muara district, sample lithologies rang...

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...

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...
