THE RALPH GRAY AWARD
:
Best Refereed Paper in Coal and Organic Petrology


A TSOP award for the best refereed paper in coal and organic petrology was approved by Council in early 2009. With the permission of the Gray family, the award was named after Ralph Gray (1923-2009), a petrologist with wide-ranging experience and interests, particularly well-known for his work in industrial applications.

For any given year, the papers considered would have been published in the previous year, ie: for the 2009 award, papers published within the 2008 calendar year can be considered. The committee started the process with evaluations of the abstracts of prospective papers. Papers authored by any of the committee members were not considered.
Final evaluation was made of the full papers of the top six selections of the committee. On rare occasions, a second award for an outstanding publication in a non-refereed venue can be considered, such as the 2008 Academic Press publication of “Applied Coal Petrology.”
