TLDR
The role of fungus in the formation of coal macerals, both as a primary contributor in the form of a fungus fossil/maceral funginite, and in their role in degrading wood, thus producing degraded maceral forms, has been established.About:

Journal ArticleDOI
On the fundamental difference between coal rank and coal type
Jennifer M.K. O'Keefe,Achim Bechtel,Kimon Christanis,Shifeng Dai,William A. DiMichele,Cortland F. Eble,Joan Esterle,Maria Mastalerz,Anne Raymond,Bruno Valentim,Nicola J. Wagner,Colin R. Ward,James C. Hower +12 more
TL;DR: The coal type refers solely to coals' depositional origin and the maceral-mineral admixture resulting from that origin, whereas coal rank refers to the changes in geochemistry and resultant changes in reflectance caused by increasing thermal maturity of the coal.

Petrology, mineralogy, and geochemistry of the Ge-rich coal from the Wulantuga Ge ore deposit, Inner Mongolia, China: New data and genetic implications
Shifeng Dai,Xibo Wang,Vladimir V. Seredin,James C. Hower,Colin R. Ward,Jennifer M.K. O'Keefe,Wenhui Huang,Tian Li,Xiao Li,Huidong Liu,Weifeng Xue,Lixin Zhao +11 more
TL;DR: In this paper, the authors reported new data on the petrological, mineralogical, and geochemical compositions of 13 bench samples of the high-Ge No 6 coal from the Wulantuga deposit, and provided new insight into the origin and modes of occurrence of the minerals and elements present.

Mineralogical and geochemical compositions of the coal in the Guanbanwusu Mine, Inner Mongolia, China: Further evidence for the existence of an Al (Ga and REE) ore deposit in the Jungar Coalfield
Shifeng Dai,Yaofa Jiang,Colin R. Ward,Landing Gu,Vladimir V. Seredin,Huidong Liu,Dao Zhou,Xibo Wang,Yuzhuang Sun,Jianhua Zou,Deyi Ren +10 more
TL;DR: The No. 6 coal from the Guanbanwusu Mine, Jungar Coalfield, Inner Mongolia, the authors has a low rank (Ro,ran = 0.56%) and a low-sulfur content (St,d ǫ= 0.58%) and the proportion of inertinite in the coal is higher than that of vitrinite (31%).

TL;DR: Peat depositional environments, the sites where and conditions under which peat accumulates, significantly influence a resultant coal's physical properties, chemical composition, and coal utilization behavior.

Geochemical and mineralogical evidence for a coal-hosted uranium deposit in the Yili Basin, Xinjiang, northwestern China
Shifeng Dai,Jianye Yang,Colin R. Ward,James C. Hower,Huidong Liu,Trent M. Garrison,David French,Jennifer M.K. O'Keefe +7 more
TL;DR: In this article, the petrological, geochemical, and mineralogical compositions of coal-hosted Jurassic uranium ore deposit in the Yili Basin of Xinjiang province, northwestern China, were investigated using optical microscopy and field emission-scanning electron microscopy in conjunction with an energy-dispersive X-ray spectrometer, as well as Xray powder diffraction, Xray fluorescence, and inductively coupled plasma mass spectrometry.

The new inertinite classification (ICCP System 1994)
TL;DR: In the ICCP System 1994, the maceral group inertinite was enlarged to include seven macerals by replacing the former maceral sclerotinite by two others, called funginite and secretinite as mentioned in this paper.

TL;DR: This study provides a phylogenetic synthesis for the Fungi and a framework for future phylogenetic studies on fungi and the impact of this newly discovered phylogenetic structure on supraordinal classifications is discussed.

TL;DR: In the ICCP System 1994, the maceral group huminite has been revised from the previous classification (ICCP, 1971) to accommodate the nomenclature to changes in the other maceral groups.

The Pre-Quaternary history of fire
TL;DR: Charcoal has been widely reported from Tertiary sediments and its appearance in the Quaternary and Recent is not solely as a result of human impact, but this interpretation is questionable as discussed by the authors.

Fate of lignins in soils: A review
TL;DR: In this paper, the authors synthesize the current knowledge and recent progress about quantity, composition and turnover of lignins in soils and identify variables determining lignin residence time.
