A large number of Mesozoic volcano-sedimentarybasins is distributed in southem Jilin Province, China, andfilled with a great set of coal-bearing strata. According tothe petroleum resources evaluation by previousresearchers, these basins have decent exploration potential（Wang Dandan et al., 2017）. The Liuhe Basin is one of thekey exploration basins in this area. So far, four geologicalexploration wells have been drilled. However, thestratigraphic correlation with neighboring regions anddetermine of the formation age for these strata in this basinis difficult due to the lack of previous basic geologicalresearch. Two zircon U-Pb ages of volcanic rocks from theoutcrops of the Lamenzi Formation, the earliest volcanics-bearing stratum in the Liuhe Basin, were first reported inthis paper, providing evidence for the discussion ofgeological age and regional stratigraphic correlation.
