Record 1 2022-10-28

English

Subject field(s)
  • Solid Fossil Fuels
  • Lignite, Graphite and Coal Mining
DEF

A black, friable band in bituminous coal, characterized by a fibrous structure and silky luster.

French

Domaine(s)
  • Combustibles fossiles solides
  • Exploit. de charbons fossiles autres que la tourbe
DEF

Type lithologique de charbon noir, à éclat soyeux, à débris de bois à structure cellulaire conservée.

CONT

Record 2 2017-05-19

English

Subject field(s)
  • Petrography
DEF

A petrographic entity, recognizable visually as a band or layer of coal that has distinctive physical appearance and characteristic microstructural features from coal to coal.

CONT

Thiessen recognized three components of banded bituminous coals-anthraxylon, attritus, and fusain.

OBS

The term component is somewhat comparable with the term microlithotype of the Stopes-Heerlem Nomenclature.

French

Domaine(s)
  • Pétrographie
DEF

Unité pétrographique reconnaissable à l'œil nu, sous forme de strates ou de lits de charbon. Son aspect extérieur est spécifique et sa microstructure distinctive.

Record 3 2012-03-01

English

Subject field(s)
  • Origins and Composition of Coal
  • Classification of Coal
DEF

Macroscopic coal constituent (lithotype) that is hard and dull gray in color.

CONT

Banded coals grade from dull banded("splint coal") to bright banded, depending on whether dull bands or bright bands are dominant. The bands are divided into four major lithotypes : durain(dull, grainy texture, tough), fusain(dull black, charcoal texture, hands get dirty), clarain(bright, satiny texture, brittle), and vitrain(bright, black, glassy, brittle).

French

Domaine(s)
  • Origine et constitution des charbons
  • Classification des charbons
CONT

Les charbons sont classés en six lithotypes en fonction de leur aspect macroscopique. On distingue les charbons humiques (lithotypes vitrain, clarain, fusain et durain) qui provienne de débris de plantes macroscopiques [et les] charbons sapropéliques (lithotypes cannel coals- spores et pollens, bogheads - algues).

CONT

Le durain est une substance, grise à brun noirâtre, à éclat mat, formant des lits fréquents mais peu abondants de quelques millimètres à plusieurs décimètres d'épaisseur. Il est fait de débris végétaux ayant perdu leur caractère originel.

Record 4 2012-03-01

English

Subject field(s)
  • Classification of Coal
  • Characteristics of Coal
DEF

Coal that absorbs rather than reflects light, containing mostly durain and fusain lithotypes.

OBS

An early division was into three types : bright coal, dull coal and mineral charcoal(or mother of coal). Another system [divided coal into] four types :fusain, durain, clarain, and vitrain. This coincided with the classification put forward by... the United States Bureau of Mines where coal is divided into anthraxylon-bright layers of plant material and attrius-darker debris material. Today coal classification is based on the organic material seen using different optical microscopic techniques. There are three main groups : liptinite(or exinite), vitrinite and inertinite with many further divisions [within these three groups].

French

Domaine(s)
  • Classification des charbons
  • Caractéristiques des charbons
DEF

Charbon lité de couleur grise et d'aspect mat.

OBS

Ce peut être soit du durain, soit un charbon à forte teneur en matières minérales.

Record 5 2011-02-04

English

Subject field(s)
  • Classification of Coal
DEF

The common variety of bituminous and subbituminous coal [which] consists of a sequence of irregularly alternating layers or lenses of homogeneous black material having a brilliant vitreous luster, grayish-black, less brilliant, striated material usually of silky luster, and generally, thinner bands or lenses of soft, powdery, and fibrous particles of mineral charcoal.

CONT

[Banded and nonbanded coals] are further subdivised into bright coal, semisplint(semibright) coal, and splint(dull) coal for banded coal; cannel and boghead coal for nonbanded coal; or the lithotypes vitrain, attrital coal(clarain, durain), and fusain.

OBS

The difference in luster of the bands is greater in bituminous than in subbituminous coal.

French

Domaine(s)
  • Classification des charbons
DEF

Charbon à composition hétérogène dans lequel des couches de couleur claire alternent avec des couches de couleur sombre.

CONT

Opaque attritus consists of three common types of organic matter all of which are opaque to transmitted light in thin section : 1. Opaque matter consisting of fusain less than 30 microns thick. 2. Amorphous opaque matter... 3. Granular opaque matter...

DEF

A lamina, for example, of ankerite or fusain, occurring on or at an angle to the bedding plane of a seam of coal.

OBS

Usually less than 3 mm thick.

French

Domaine(s)
  • Exploit. de charbons fossiles autres que la tourbe
DEF

Lamelle, par exemple d'ankérite ou de fusain se rencontrant en concordance ou en discordance avec le plan de stratification d'une veine de charbon.

OBS

Record 8 1998-03-12

English

Subject field(s)
  • Origins and Composition of Coal
DEF

Constituents of coal which decrease its efficiency in use, for example, mineral matter(ash) and moisture in fuel for combustion, or fusain in coal for carbonization.

French

Domaine(s)
  • Origine et constitution des charbons
DEF

Éléments constitutifs du charbon qui diminuent son efficacité dans l'emploi, par exemple matières minérales (cendres) et humidité pour le combustible ou le fusain dans le charbon pour la carbonisation.
