In this paper, the authors analyzed major and trace element compositions of fifty samples of clastic sedimentary rocks from this section. Combined with data previously publicized by others, the conclusions are as follows: firstly, this set of sedimentary rocks share similar chemical characteristics to the associated volcanic rocks, with LREE enrichment, flat HREE, high-Mg^#, high contents of large ion lithophile element (LILE) and variable REE anomalies. Their spider diagrams show significant negative Nb and positive Pb anomalies. It is deducted that the sedimentary rocks were mainly derived from the high-Mg^# volcanic rocks from the Yixian Formation. Secondly, these sedimentary rocks show variable Eu anomalies (Eu/Eu^*=0.48~1.81)with the average value being 0.75.
