Geochemical characteristics, identification index and origin of immature oils are investigated in terms of organic geochemical analyses of crude oils and source rocks from the Wuyang and Xiangcheng basins.

Formation condition for immature to low-mature oil in Xiangcheng Depression

Palaeogene immature petroleum system in the Wuyang Sag, Zhoukou Depression;

In this paper,the zirconite cathodeluminescence and dating data are used to analyze the provenance of Hetaoyuan formation in Wuyang sag.

Using zircon\'s fission track age technique can determine the palaeo-source age and direction of Wuyang sag.
