The 50-mm-diameter pre-weighed cores were used to investigate the …In thin section it is distinguished by its opaqueness and cellular structure. Thiessen's system of classifying coal into types after thin section analysis is based on the aggregate character of the coal in terms of limiting quantities of the petrographic components or ingredients. The coal seam section is divided based on the macroscopic coal lithotypes and the coal structure, and the observed orientation and density of natural fractures are measured. Because of the limitation of the observation space and the variation of coal seam thickness, the thickness of the coal seam section is different, which is about 2 m.Thin Section Descriptions Also included in this report are thin section descriptions of numerous outcrop and borehole samples taken as part of the USGS exploratory program.
