Inertinite - Wikipedia
网页Inertinite refers to a group of partially oxidized organic (mainly plant) materials or fossilized charcoals, all sharing the characteristic that they typically are inert (i.e. not altered) when heated in the absence of oxygen. Inertinite is a common maceral in most types of coal.
Inertinite | maceral group | Britannica
网页The inertinite group makes up 5 to 40 percent of most coals. Their reflectance values are usually the highest in a given sample. The most common inertinite maceral is fusinite, which has a charcoal-like appearance with obvious cell texture. The cells may be …
The new inertinite classification (ICCP System 1994)
网页2001年3月1日 · In the new classification (ICCP System 1994) the maceral group inertinite has been enlarged to include seven macerals by replacing the former maceral sclerotinite by two others, called funginite and secretinite.
Assessing biochar's permanence: An inertinite benchmark
网页2024年1月5日 · Inertinite is the most stable maceral in the Earth's crust and is hence considered an ultimate benchmark of organic carbon permanence in the environment. Therefore, this study aims to measure the degree of biochar's carbonization with respect to the well-established compositional and microscopic characteristics of the inertinite.
Characteristics and evolution of inertinite abundance and …
网页2021年5月20日 · Coal, especially the inertinite in it, is highly sensitive to climate changes, showing an obvious response to paleoclimate conditions, in particular, to paleo-oxygen concentration (pO2). In this study, the inertinite abundance data of typical coal-forming periods in China were systematically collected and analyzed.
Inertinite - an overview | ScienceDirect Topics
网页The inertinite group takes its name from the fact that its members characteristically undergo little reaction or alteration when the coal in which they occur is carbonized (i.e., heated to high temperature in the absence of oxygen). The macerals of this group have a higher reflectance than those of the other groups, giving them a light gray ...
Inertinite in coal and its geoenvironmental significance ... - Springer
网页2024年5月14日 · Inertinite, as an important and abundant maceral group in coal, is critical for the study of palaeowildfires and their roles in the Earth’s ecosystems. Recently, there has been a significant amount of research on the relationship between palaeowildfire, palaeoclimate change and palaeovegetation evolution based on inertinite data.
Maceral groups: (a) vitrinite; (b) liptinite and inertinite; (c ...
网页On this basis, three groups of macerals were distinguished: liptinite, vitrinite, and inertinite ( Figure 1) [9][10][11]. The color of liptinite changes from brown through dark grey to light grey...
Differences in Molecular Structure between Vitrinite and Inertinite …
网页2023年12月12日 · Vitrinite is a product of the gelification process of plant lignocellulosic tissue during coal formation. Compared with inertinite, vitrinite has a higher oxygen content and a slightly lower carbon content.
Coal Macerals - SpringerLink
网页2016年1月1日 · On the basis of plant cell structure and morphology, seven macerals are classified under inertinite group. Contrary to vitrinite, the inertinite classification can be applied to the organic matter of all coalification stages from peat to high-rank coal, and the subdivision of the maceral group is simpler since there are no subgroups.
