โœฆ Synopsis

An empirical relationship between carbon and hydrogen contents of coals and their measured vitrinite reflectances R v, max (henceforth R o ) determined from published data for 210 samples of Australian coals from more than 60 different seams, shows that R o depends upon both the carbon and hydrogen content via the equation %R o = -5.035 + 0.0804%C -0.184%H. This equation allows prediction of the change in R o when the carbon and/or hydrogen content vary. The equi-reflectance lines plotted on a Seyler chart using this equation allow prediction of the variable suppression of R o caused by changes in hydrogen content.

The Springfield (No.5) coal, a Pennsylvanian-age high volatile B bituminous rank coal in the Carbondale Formation, is mined in the southeastern section of the Illinois Basin. Intruded into this coal is a 10.1-m-wide basic dike that is near vertical through the extent of the mined coal bed, and strik
