In 1999 a statistical study carried out by Lopo Vasconcelos and published in Intern. J. Coal Geol., 40 (1999) 27-58 was presented in Bucharest during the 59th Annual Meeting of the ICCP, being this the first approach to the problem with the objective of observing the petrographic variations of coals with age. Besides temporal variations Palaeozoic coals also showed differences between environments of Gondwana and North Atlantic coals. The study did not consider environment, basin type, etc.
The objective of this WG is to study these variations, especially for Palaeozoic coals; it would be therefore interesting to study VLI-compositions within basins world-wide.
