  1. Fouriertransformation infro - red microspectroscopy micro - ftir technique was used to investigate the chemical compositions and structures of cutinite, vitrinite and fusinite from jurassic coals in tarim basin at different temperatures. the results show that the chemical structure of cutinite is mainly composed of long aliphatic - side chain with minor amounts of aromatic compounds. vitrinite is mostly composed of aromatic compounds, in addition to large amount of short aliphatic - side chain compounds. whereas fusinite are dominant by aromatic structure. the study indicates that cutinite is one of the best oil source - rocks, with the higher hydrocarbon - generation potential ; vitrinite is one of better gas source - rocks, and has medium hydrocarbon - generating potential ; fusinite has little hydrocarbon - generating potential. in addition, the components of aliphatic structures of cutinite, vitrinite and fusinite decrease, the aromatics are enriched and condensation of aromatic structure increases with increasing the temperature, and along with the rise of temperatures, the intensity of aliphatic structure and heteroatomic compounds decrease obviously, however the aromatic structure changes a little
