摘要
In this paper, the features and classifications of laser Raman spectrum of three macerals (vitrinite, semifusinite and fusinite) in source rocks were discussed. The comparisons of laser Raman spectrum parameters between different macerals were made and the structures of different macerals were analyzed. It has been found out that, in certain maturity range, obvious difference exists between D1 peak and G peak half-width among different organic macerals. This might be used as a new standard to distinguish different organic macerals. Laser Raman spectrum identifies the macerals in coals and rock samples quickly and effectively. It is an effective method in maceral analyses.
