TL;DR: The ASTM D7708: standard test method for microscopical determination of the reflectance of vitrinite dispersed in sedimentary rocks was published in 2012 as discussed by the authors, and an inter-laboratory exercise was conducted to establish precision limits for the D 7708 measurement.

TL;DR: The results of these round robin exercises are useful for improving the identification of sedimentary organic matter in source rocks and may be an important foundation for the modification of the ICCP definitions of alginite and bituminite as discussed by the authors.

TL;DR: In this article, the results obtained by 22 analysts who were asked to measure random reflectance readings on vitrinite particles assigning to each reading a qualifier were reported, and the results indicated low to medium dispersion for 17 out of 22 participants.

••
TL;DR: In this article, a review of organic petrography applications in the North American shale plays through discussion of incident light photographic examples is presented. But, the work is limited to the use of high-resolution imaging techniques and in situ geochemical probing.
338 citations
••
TL;DR: In this article, the authors used the concept of a "chessboard" to classify mineral resources in the mixtum compositum of all geoscientific disciplines focused on one goal, finding new mineral depsosits and enhancing their exploitation.
329 citations
••
TL;DR: The coal type refers solely to coals' depositional origin and the maceral-mineral admixture resulting from that origin, whereas coal rank refers to the changes in geochemistry and resultant changes in reflectance caused by increasing thermal maturity of the coal.
250 citations
••
TL;DR: A review of coal petrology in geosciences can be found in this paper, where the authors describe and update the role of organic petrology and its applications in coal utilization.
