| Abstract: | Lingwu coalfield is located in the western margin of Ordos basin.The coal-bearing rock series-Yanan Formation,250～350m in thickness,contains more than 20 coal seams.Coal seams of No.2 and No.14 are the main ones.The author discusses the characteristics of steroid and terpenoid of vitrinite and inertinite in coal seams No. 2 and No.14.It is concluded the characteristics of steroid and terpenoid of vitrinite and inertinite show regular changes in the same sedimentary environment.Also,the characteristics of steroid and terpenoid of the same maceral(vitrinite or inertinite)change regularly in different sedimentary environments. |
