英文摘要: Abstract(#br)The origin of oil in the Tarim Basin, northwestern China, has been debated for decades. Here we present new insights into this challenging issue based on data from the Bachu-Maigaiti area, combined with a synthesis of data from other oil fields in the basin. Results of the organic geochemical characterization of 39 oil samples from various fields using GC–FID, Py–GC, GC–MS and GC–MS–MS revealed that the oils in the Tarim Basin can be generally classified into three families. The oils of the first family, whose representatives in our study come from the Luntaibei condensate field, are terrigenous as indicated by highest pristane/phytane (>2.8) and methylcyclohexane/ n -heptane (>1.8), and lowest dibenzothiophene/phenanthrene (<...
