We studied the sedimentary and tectonic environment of the Carboniferous Luquantun Formation in the section of Panshi area of central Jilin��by means of analysis of lithology and element geochemistry of the sam- ples�� The results showed that the concretion samples are featured by high constant elements of Si��Fe and low con- stant elements of K��Na�� The mudstone samples are characterized by trace elements with high contents of Sr��Zr�� Ba and V and low contents of Be��Ta��Tl��Bi and U�� ��are earth elements performance showed significant differ- entiation��and light rare earth elements were relatively enrich��but δEu was negative abanomaly�� The main sedi- mentary environment was marine reducing environment with the sediments of delta facies and marine facies��and the tectonic setting was continental island arc��
