| Abstract: | Using photometric and image analysis methods, a reasonable technique and procedure have been developed for the determination of maceral group composition and the reflectance of vitrinite. This procedure is introduced by an optimum method for seeking the interval values of each maceral group, i.e., from the “fingerprint” reflectance histogram, it seeks reasonable interval values and distribution values for vitrinite and other maceral groups. After checking and correction, these values can be put into a program and computerized. This method had advantages such as increased speed of analysis and reproducibility of the results. |
