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].

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
