Analyses of coal macerals employ observations of both dispersed organic matter and coal in reflected light. They determine macerals within three groups: vitrinite, liptinite and inertinite. Additionally, vitrinite reflectance (Ro) is analyzed.
Microscope analyses are carried out in accordance with ICCP recommendations.
Petrographic analyses of organic matter are carried out both in white and ultraviolet light using a Carl Zeiss Axioskop microscope.
Vitrinite reflectance is determined with an MSP 200 photometer coupled with a Carl Zeiss Axioskop microscope.
The results of the analyses are presented in reports which include data gathered from qualitative and quantitative analysis of maceral composition, vitrinite reflectance (Ro) data and micro-photographs used during observations.
