摘要
Based on the testing and analyzing of trace elements and rare-earth elements of 333 sedimentary rocks from Shengke-1 well, the sedimentary environment, provenance and tectonic setting on the Mesozoic and Paleozoic are revealed in Southern Jiangsu Province. The research indicates that the Upper Chisia Formation in Southern Jiangsu Province presented apparently oxygen-rich characteristic. Based on the δEu、the REE distribution pattern and La/Yb-∑REE, the provenances of these stratums are the upper earth shell and there are many provenances. The source rocks of Gaojiabian Formation and Fengtou Formation of Silurian are dominated by sedimentary rock and granite. The source rock of the Wutong Formation is sedimentary rock from Cathaysia and Jiangnan uplift.
