Inertinite maceral compositions in coals from the Early Cretaceous Erlian, Hailar, and Sanjiang Basins in NE China are analyzed in order to reveal palaeowildfire events and palaeoclimate variations. Although huminite ...
also an important geological information carrier of coal forming environments.In the southern section of the Ordos Basin,the No.4 inertinite-rich coal seam of the Middle Jurassic Yan’an Formation in the Binchang Coal...
Coal contains a significant concentration of free radicals as a result of the coalification process. One of the experimental methods sensitive to the presence of radicals is electron spin resonance (ESR), and differ...
