Zircon fission track analyses of sediments of sedimentary basins can be used to trace its provenance characters and tectonic evolutional history. Central ages of zircon fission tracks of 9 Cenozoic sandstones from the Jiyang Depression arrange from (183.1±15.0) Ma to (100.1±5.6) Ma, and all the single zircon grain age is bigger than its strata depositional age. Multiple component analyses of zircon fission track ages were calculated. Combined with regional geological background, it can be concluded that volcanic rocks and volcano-clastic rocks of the Upper Jurassic to Lower Cretaceous strata which were formed due to the intense tectono-magmatic activation of the Middle Yanshannian movement are the chief provenance to Cenozoic strata of the depression.
