Applied Coal Petrology: The Role of Petrology in Coal ...
Maceral Analysis For geological research on coal basins and for an evaluation of
coal seam quality it is important to know the quantitative composition of a coal in
terms of the macerals (and minerals in some cases) or maceral groups. This is ...

Field Description of Coal: A Symposium
With regard to the connection between maceral composition and litho- type

Huminite/vitrinite in coal According to coal petrographic classification, based on
morphology, the huminite/vitrinite maceral group has three subgroups: telinite (
preserved plant cell structure), detrinite (detrital part of both arboreal and ...

Mining, Challenges of the 21st Century
Amoco's study AMOCO analysed several samples of coal from Damodar Valley
coalfields for maturity, coal quality, maceral content and sorption. The coal
samples, analysed and used in the study, were obtained from the year 1990 to
1994.

The Chemistry and Technology of Coal, Third Edition
By convention, maceral names always have an -inite suffix. Thus, macerals are
generally divided into the vitrinite (or huminite in lower-rank coals), inertinite, and
liptinite groups. Huminite/vitrinite macerals are derived from humic substances, ...

Sedimentation of Organic Particles
However, this never occurs, and in order to evaluate the relationship the sample
maceral spectra has to the population maceral spectra, the sources of variation
which affect organic matter sedimentation must be determined and understood.

New Trends in Coal Preparation Technologies and Equipment
The use of image systems to perform maceral analysis is discussed and several
new methods are explored. A semi-automated technique is also described, which
uses software functions to operate the microscope, the program also allows ...
