《"Lipid Biomarkers and Their Stable Carbon Isotopes in Ancient Seep Carbonates from SW Taiwan, China"》
Hydrocarbons were the most abundant class of organic compounds，whereas only a few polar lipid biomarkers were preserved in the carboxylic acid and alcohol fractions.The predominant hydrocarbons were n-alkanes with chain lengths from C14 to C36，peaking at n-C17 and nC27，with bimodal distributions in sample BG-12（Fig.3）.By contrast，the n-alkanes in the total ion chromatograms（TIC）of carbonate samples JA-4，JA-5 and JX-8 were characterized by unimodal distributions with n-C16/n-C17as the most abundant components.In addition to the nalkanes，isoprenoids of pristane and phytane were the most abundant isoprenoids withδ13C values ranging from-30.6‰to-48.0‰（Fig.2；Table 1）.
