BIMACERAL [4 fiches]

Fiche 1 2012-03-01

Anglais

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

A coal microlithotype that contains a combination of inertinite and exinite.

OBS

The term microlithotype was developed to permit the designation of rock types within coal that are at a microscopic scale and their definition is based on maceral percentages. All macerals have a suffix "-inite" and microlithotypes have the suffix "-ite. "Thus, layers greater than 0. 05 mm in thickness and consisting of greater than 95% vitrinite are termed vitrite. Bimaceral(clarite, durite and vitrinertite) and trimaceral(duroclarite and clarodurite) microlithotypes have names that are derived from lithotypes rather than macerals.

Fiche 2 2007-06-11

Anglais

Subject field(s)
  • Classification of Coal
DEF

A coal microlithotype consisting of a single maceral.

CONT

At the microscopic level, the associations of coal macerals are named microlithotypes. They have been classified into three main groups : monomaceral, bimaceral and trimaceral according to whether a microlithotype contains one, two or three maceral groups. The monomaceral microlithotypes "vitrite", "liptite" or "fusite" must contain not less than 95% vitrinite, liptinite or inertinite and not more than 5% other maceral groups, respectively.

OBS

A maceral is a component of coal. The term "maceral" in reference to coal is analogous to the use of the term "mineral" in reference to igneous or metamorphic rocks. Examples of macerals are inertinite, vitrinite and liptinite.
