| Summary: | 碩士 === 國立中央大學 === 應用地質研究所 === 89 === In order to identify macerals in a quick and easy way, a 2:1 FeCl3 and K3Fe(CN)6 mixing solution is applied as a dye for coal. After series of dyeing experiments, the standard dyeing procedures were established. Furthermore, the vitrinite reflectance data were measured after dyeing, then calibrated back to their original value, so as to estimate their maturity correctly. The experiment results indicate that 50 minutes is the most proper soaking time in dye.
The same dye was applied on coal , kerogen and coaly shale, respectively so as to evaluate the suitability of this technique in solving the problem of measuring maturity of source rocks. The results indicate that 1) the color of vitrinite turned to bright yellow after dyeing；2)the reflectance of vitrinite after and before dyeing can be expressed in the equation： (dyeing)= 0.94 (no-dyeing)+ 0.26(%)；3)the dyeing technique can be applied on the source rocks.
