The Age-Related Biomarkers Tested by GC-MS-MS Technologies and Their Geological Significances

Abstract

Abstract: By means of GC-MS-MS method, the multiple series of age-related and taxon specific biomarkers are tested in source rocks and oil samples from Liaohe oilfield and Tarim basin, which are hard to be detected by conventional GC-MS method. They are steranes, methylsteranes, Tricyclic and tetracyclic diterpanes, methyl hopanoid alkanes and hexacyclic hopanoid alkanes, etc. High content of norsteranes and Dinosteranes that were found after Mesozoic broadly occurred in Cambrian source rocks in Tarim basin, postulating that the precursors might even exist in the period of Cambrian biologic explosions. These molecular evidences and age-related significance given by GC-MS-MS method have been used for distinguishing the crude oils of Middle-Upper Ordovician from Cambrian in Tarim basin, playing an important role in approach to Tarim oil sources that have disputed for a long time.

Key words: Tarim basin, gas chromatography (GC), mass spectrography (MS), detection, biomarker
