Spontaneous coal combustion (SCC) is one of the significant hazardous phenomena in underground coal mines. The tendency of spontaneous coal combustion is an intrinsic property, due to the presence of the maceral content. Unlike its importance, this matter has not been discussed in detail among the researchers. Therefore, it is necessary to investigate the effect of this parameter on SCC. Macera...

Coal, which is usually land plant in origin, occurs in many oil-producing basins. Microscopically, coal consists of various macerals (liptinite, vitrinite, and inertinite). The generative potential of coal reflects the hydrocarbon potential of the composing macerals (Kelly et al., 1985). Although most coals consist of predominantly vitrinite, some contain significant amounts (>20% of total mace...

introduction maceral is a term to introduce organic components visible under a microscope (stopes, 1935). the physical and chemical characteristics of macerals such as elemental composition, moisture content, hardness, density and petrographic characteristics differ. the differences in the physical and chemical characteristics of macerals are reflected in their industrial behavior.(parkash, 198...

At a symposium honoring the 50th anniversary of University Chicago, Gilbert Cady introduced concept phyterals as means distinguishing actual plant fossils from macerals composed fossils. In this sense, vitrinite and fusinite, while distinct macerals, are viewed same phyteral. contrast to such process-induced in vs. phyterals, funginite, regardless rank, age, or type fungus producing structure, ...

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 Menilite Formation Iwonicz-Zdrój–Rudawka Rymanowska Fold (IRF) Bóbrka–Rogi (BRF) Central Carpathian Synclinorium Silesian Nappe, Outer Carpathians, Poland. The investigation was carried out at two-unit depths s...
