ABSTRACT OF THESIS THE NO. 5 BLOCK COAL IN EASTERN KENTUCKY: A CRITICAL RE- EXAMINATION OF THE PETROLOGY WITH SPECIAL ATTENTION TO THE ORIGIN OF INERTINITE MACERALS IN THE SPLINT LITHOTYPES Microbes, including fungi and bacteria, and insects are responsible for the consumption and subsequent degradation of plant materials into humus. These microbes directly and indirectly affect the physical and chemical characteristics of coal macerals. Efforts to understand and determine the origins of inertinite macerals are largely misrepresented in the literature, conforming to a single origin of fire. This study focuses on the variability of physical and inferred chemical differences observed petrographically between the different inertinite macerals and discusses the multiple pathways plant material may take to form and or degrade these macerals. Petrographic results show that fungal activity plays a fundamental role in the formation of inertinite macerals, specifically macrinite and non-fire derived semifusinite. Fungal activity chemically removes the structural framework of woody plant tissues, forming less structured to unstructured macerals. Insect activity within a mire also greatly influences the inertinite maceral composition. Wood-consuming insects directly degrade wood tissue leading to the formation of less structured inertinites, as well as producing large conglomerates of inert fecal pellets chemically similar to the original plant tissue that may be represented in the inertinite maceral composition.

    CHEMICAL AND PHYSICAL STRUCTURAL STUDIES ON TWO INERTINITE-RICH LUMP COALS. Nandi Malumbazo A thesis submitted in fulfilment of the requirements for the degree of Doctor of Philoso- phy in the School of Chemical and Metallurgical Engineering at the University of the Witwatersrand. Johannesburg, 2011 DECLARATION I, Nandi Malumbazo, declare that the thesis entitled: “CHEMICAL AND PHYSICAL STRUCTURAL STUDIES ON TWO INER- TINITE-RICH LUMP COALS” is my own work and that all sources I have used or quoted have been indicated and ac- knowledged by means of references. Signature: ……………………………………………………………….. Date:………………………………………………………………………… Page i ABSTRACT ABSTRACT Two Highveld inertinite-rich lump coals were utilized as feed coal samples in order to study their physical, chemical structural and petrographic variations during heat treat- ment in a packed-bed reactor unit combustor. The two feed lump coals were selected as it is claimed that Coal B converts at a slower rate in a commercial coal conversion process when compared to Coal A. The reason for this requires detailed investigation. Chemical structural variations were determined by proximate and coal char CO2 reactiv- ity analysis. Physical structural variations were determined by FTIR, BET adsorption methods, XRD and 13C Solid state NMR analysis. Carbon particle type analysis was con- ducted to determine the petrographic constituents of the reactor generated samples, their maceral associations (microlithotype), and char morphology. This analysis was undertaken with the intention of tracking the carbon conversion and char formation and consumption behaviour of the two coal samples within the reactor. Proximate analysis revealed that Coal A released 10 % more of its volatile matter through the reactor compared to Coal B.

The Jungar coal is of high volatile C/B bituminous quality with 0.58% vitrinite reflectance and has a low sulfur content of 0.70% on average. Inertinite (mineral-free basis) generally dominates in coal from the lower part of the Shanxi formation, and vitrinite is the major maceral assemblage in the coal from the Taiyuan formation, which exhibits forms suggesting variation in the sedimentary environment. The Jungar coal is characterized by higher concentrations of copper (Cu) in No.

    Wang et al. Journal of Palaeogeography (2019) 8:17 https://doi.org/10.1186/s42501-019-0035-5 Journal of Palaeogeography ORIGINAL ARTICLE Open Access Characteristics of Early Cretaceous wildfires in peat-forming environment, NE China Shuai Wang, Long-Yi Shao*, Zhi-Ming Yan, Ming-Jian Shi and Yun-He Zhang Abstract 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 is the dominant maceral group in the studied basins, the inertinite group, as a byproduct of palaeowildfires, makes up a considerable proportion. Occurrence of inertinite macerals indicates that wildfires were widespread and frequent, and supports the opinion that the Early Cretaceous was a “high-fire” interval. Inertinite contents vary from 0.2% to 85.0%, mostly within the range of 10%–45%, and a model-based calculation suggests that the atmospheric oxygen levels during the Aptian and Albian (Early Cretaceous) were around 24.7% and 25.3% respectively. Frequent fire activity during Early Cretaceous has been previously related to higher atmospheric oxygen concentrations. The inertinite reflectance, ranging from 0.58%Ro to 2.00%Ro, indicates that the palaeowildfire in the Early Cretaceous was dominated by ground fires, partially reaching-surface fires. These results further support that the Cretaceous earliest angiosperms from NE China were growing in elevated O2 conditions compared to the present day.
