Palynofacies analysis, sedimentology and hydrocarbon potential of the Menilite Beds (Oligocene) in the Slovakian and Romanian Outer Carpathians [PDF]

open access: yesGeological Quarterly, 2020
The sedimentary organic matter (SOM) assemblages and sedimentology of the Menilite Beds from the Dukla, Grybow and Vrancea units in the Slovakian and Romanian Outer Carpathians are described. Qualitative and quantitative analyses of the SOM help ascertain depositional conditions, while the thermal maturity of the organic matter studied is estimated ...

Palynofacies analysis of Naokelekan formation, Northern Iraq

open access: yes, 2019
Palynofacies analysis of 38 rock samples of the Late Oxfordian-Early Kimmeridgian Naokelekan Formation from two exploratory wells and two outcrops in northern Iraq was performed. All samples taken from outcrops in Duhok and Sulaymaniyah provinces and well Bj-1 in northern Iraq were classified as palynofacies Type I (PF-1), which comprises mainly ...

Palynofacies patterns of the Highveld coal deposits (Karoo Basin, South Africa): Clues to reconstruction of palaeoenvironment and palaeoclimate

open access: yesActa Palaeobotanica, 2016
The early Permian represents a crucial period of climate change in Gondwana. This climate signature is captured in the palynological record that represents the floral assemblage of the region. Palynofacies analysis of the No.

Integrated Organic Geochemistry and Palynofacies Analysis of Organic Matter in the Pirara Formation, Tacutu Basin

open access: yesAnuário do Instituto de Geociências
The Tacutu Basin developed during the Mesozoic from an intracontinental rift related to a triple junction formed in the Jurassic. It is located on the border between the state of Roraima, Brazil, and the Upper Takutu-Upper Essequibo district, Guyana.
