Abstract: In view of the forming mechanism of oil shale in Maoming basin, the authors studied the organic geochemical characteristics, and discussed the origin of organic matters and depositional environment of Eocene Youganwo Formation oil shale in Yangjiao mining area based on Leco, rock pyrolysis, oil yield, and biomarker analysis. The results show that the abundance of organic matter is high, the kerogen is type Ⅰ-Ⅱ1, the average oil yield is 5.98%, and the quality of oil shale is fairly high. ICP (3.73-4.37), OEP (7.59-9.57), low C29ααα20S/(20S+20R), low Ts/(Ts+Tm),and Tmax (428-434℃) indicate that the oil shale thermal evolution of Youganwo Formation is in immature stage. The gas chromatography (GC) of n-alkanes has the features of unimodal distributions with nC27 as the mean peak. ∑C21-/∑C22+ and ∑C21+22/∑C28+29 are low, ICP and OEP are high. The content of high-carbon hopanes is high,while the content of tricyclic terpenes is low. No non-hoprii compounds such as oleane and lupane are detected. Combined with the relative content of C27-C28-C29,all the above indicate that lacustrine algae, mixed sources of plankton and terrestrial plants are the main source of organic matter of the oil shale of Youganwo Formation. TOC/S (41.14-170.08), Pr/Ph (0.82-1.30), and rearranged sterane/sterane (0.06-1.10) indicate that the paleo-lake condition was fresh and reductive when oil shale deposited. In a subtropical-temperate warm-humid climate, high lake productivity is caused by aquatic organisms such as algae bloom, and reductive fresh water environment is favorable for oil shale mineralization in Youganwo Formation of Maoming basin.

Key words: oil shale, organic geochemistry, origin of organic matters, depositional environment, Youganwo Formation, Maoming basin
