| 摘 要： | 选择了不同地区和时代的不同变质程度的5个系列的煤样,对分离富集的镜质体主要特征进行了比较研究。研究发现:按海相和陆相划分,属同一相的不同时代的等变质煤的镜质体性质仍有差异,有些甚至相当明显。这表明,等变质煤镜质体性质存在的差异具有普遍性,并且其成因不止有煤相一个因素。

| Abstract: | In this topic five series of coal samples with different metamorphism degrees are selected from different areas and ages."Hie comparative researches are carried out on the main characteristics of the vitrinites concentrated by separation. It is found that dividing by the marine facies and continent facies, the vitrinite properties in the iso-metamorphosed coals belonging to the same facies but different ages still have the differences,and some differences are even more obvious.This indicates that the property diversity existed in the vitrinites in iso-metamorphosed coals has the universality, and its genesis is not limited to one factor,the coal facies. |

| Keywords: | iso-metamorphism vitrinite diversity |
