Raman spectroscopy on carbonaceous material has become the most used
geothermometer in Earth science studies. However, its application in very different settings …

Organic petrology developed from coal petrology, and, in the 1960s, it began to be applied
to the study of dispersed organic matter (DOM) in sedimentary rocks other than coal. Over …

Abstract Central Carpathian Paleogene Basin (CCPB, Central Western Carpathians)
comprises mainly Oligocene clastic autochthonous age-equivalents of the widely known …

It is a challenge to accurately characterize the caking behavior of coal after thermal softening
and its reaction mechanism. In this work, the formation behavior of metaplast during coal …

To refine the use of graptolite and solid bitumen as thermal proxies at overmature
conditions, we evaluated their evolution via Raman and infrared (IR) spectroscopies …

This study presents Raman spectroscopic data paired with scanning electron microscopy
(SEM) images to assess solid bitumen composition as a function of solid bitumen texture …

Sapropelic coals were taken for study from coal mines and coal waste dumps in Upper
Silesian Coal Basin (USCB), Poland. They showed unusual molecular compositions …

To further refine the use of solid bitumen reflectance (BRo in%) as a measurement of
thermal maturity in source-rock reservoirs, we examined its relationship to other thermal …

It is of great significance to reveal the specific separation behavior of macerals for realizing
the classification and utilization of coal resources. In this article, the separation mechanism …

Elucidating the molecular structure of sedimentary organic matter (SOM) is key to
understanding petroleum generation processes, as well as ancient sedimentary …
