Vitrinite histograms of random reflectance measurements for Menilite Formation samples from the Iwonicz-Zdrój-Rudawka Rymanowska Fold -shallow part of D-1 well section
Source publication
In this study, optical microscopic analyses were applied to evaluate the thermal maturity, characteristics of solid bitumen, and other organic matter finely dispersed in Oligocene shales of the Menilite Formation in the Iwonicz-Zdrój–Rudawka Rymanowska Fold (IRF) and Bóbrka–Rogi Fold (BRF) of the Central Carpathian Synclinorium of the Silesian Napp...

... is solid bitumen (2.1% vol., on average, range from 1.0 to 2.9%) ( Fig. 6G-I). The solid bitumen is represented by homogenous ( Fig. 6I) and granular (Fig. 6F) forms (Landis & Castaño 1995). The observed inertinite macerals (0.6% vol. on average, ranges from 0.5 to 0.8%) (Tab. 3) are fusinite, semifusinite, and inertodetrinite. In one sample (No. 11, depth 4,305 m), the evidence for liquid hydrocarbons (thin green film impregnated in fissures of solid bitumen) was noticed (Fig. ...

... The interpreted salinity changes are important to acquire a better understanding of the organic matter preservation of the Menilite Formation, which is well known for its hydrocarbon potential (e.g., Wójcik-Tabol et al., 2022). The organic petrography in the Oligocene of the Carpathians' successions has been mainly used as an indicator of organic matter origin and hydrocarbon potential (Kruge et al., 1996;Puglisi et al., 2006;Miclȃus et al., 2009;Belkin et al., 2010;Waliczek and Więcław, 2012;Wójcik-Tabol, 2015, 2017Wendorff et al., 2017;Kosakowski et al., 2018;Ziemianin, 2018Ziemianin, , 2020Zielińska et al., 2020;Waliczek et al., 2022). ...
... Telalginite may have two algal sources: marine (e.g., Tasmanites) or fresh-water (Botryococcus) (Hutton, 1987). Typical Tasmanites have not been observed in the samples, although they have been described in the Menilite Shales (e.g., Ziemianin, 2018;Waliczek et al., 2022). The examined telalginite rather resembles Botryococcus, a freshwater algae that can also occur in sediments deposited in marine environments. ...
... Therefore, telalginite, which may originated from marine algae and/or from the fresh-water Botryococcus has often been recognised in saline water deposits (Liu et al., 2022;Shi-Ju et al., 2023). The Botryococcus has been also described in the bituminous shales of the Menilite Formation and its analogue from the Romanian Outer Carpathians (Waliczek et al., 2022;Filipek, 2020). ...
