Abstract: Part of oils generated from the M anjiar depression has medium to high wax content. Based on thedistribution of the wax content of oils, analysis of biomakers in bacteria and algae and the results of sim-ulation experiments, it was considered that the high wax content in the oils from the Lower Paleozoic ofthe both south and north uplifts in the Manjiar depression is chiefly related to algae,due green algae andbacteria which aenthe main organic origin in the Lower Paleozoic·of the tended isoprenoids and hopanoids originated from blue green algae and bacteria were fornd in tracts and oils. Extendedn alkanes also existed in the pyrolytic products of recent plankton blue green algae. Abundance ofwaxy n}-akanes could also be caused by the geochromatographic effects during migration.
