Abstract:

The GC-MS and HPLC methods were used to determine geoporphyrins in the present work. Compounds in HPLC were assigned by coinjections with Gilsonite bitumen,Serpiano oil shale and Boscan oil. Meanwhile the compounds in GC-MS were identified by coinjection with the porphyrin standards which isolated from Gilsonite bitumens, Serpiano oil shale and Boscan oil. The results show that porphyrin distributions in Chinese samples,which were collected from different lacustrine palaeoenvironmentS, are pronounced distinguishable. Samples from fresh water lacustrine are dominated in C32, C31 13, 15-Ethano CAP. Samples from hypersaline water lacustrine are characterised by unknown CAP com-pounds, C31 13, 15-Ethano CAP. However, the coal samples are dominated in aetio compounds. These divergences imply there are different porphyrin precursors and porphyrin transformations (in water column and early diagenesis) in different palaeoenvironments.
